Cosmotography receives Advanced Imaging Conference 2019 Hubble Award

R, Jay GaBany, the author of Cosmotography, has been selected to receive the 2019 Hubble Award from the Advanced Imaging Conference during its San Jose, California meeting from November 15-17, 2019.

According to the conference directory:

"R. Jay GaBany has the reputation for producing some of the finest deep-sky photography in the world. His images have been featured and published countless times in magazines, books, movies, and of course Astronomy Picture of the Day.

His many contributions to the astrophotography community are vase. Best known for his work with an international team of astrophysicists, led by Dr. David Martinez-Delgado, he helped pioneer the use of modest sized telescope using off-the-shelf equipment to produce long exposure images that revealed ancient galactic merger remnants in the form of star streams surrounding near-by galaxies that were previously undetected. His long exposures and special processing methods managed to capture details not seen in professional images.

GaBany's scientific collaboration with professional astronomers has resulted in his participation as co-author of 16 peer-reviewed papers. His writings include over 50 published articles in numerous popular astronomy magazines, books and on-line blogs. GaBany was awarded the 2010 American Astronomical Society (AAS) Chambliss Amateur Achievement Award. Time magazine included GaBany with their compilation of the 25 most Influential People in Space and Parade magazine included Jay in their list of 10 most influential People in Space.

Jay also served as a board member and President of AIC, helping to plan conferences, writing code for registration, creating the AIC website and producing the newsletter. Jay retired from AIC in December 2018 and is currently living in San Jose with his wife, Anne"

Cosmotography Image Appears in the 5 October, 2018 Issue of the Journal Science

The Stellar Ring around NGC5907
Eric Hand is a deputy editor responsible for physical sciences news coverage with the Journal Science. In the October 5, 2018 issue, he writes that stellar streams are like necklaces of stars. They stretch across the Milky Way's halo, a sparse and roughly spherical region of stars that envelops the galaxy's whirling disk like a snow globe. They are the filamentous remains of neighboring small galaxies and star clusters that have been disemboweled as they fall into the galaxy's gravitational grasp. And their study is now entering a golden age, with astronomical surveys like the European Space Agency's Gaia pushing into the far reaches of the Milky Way's halo. Even before Gaia, astronomers were finding streams in data from ground-based observing campaigns such as the Sloan Digital Sky Survey and the Dark Energy Survey. Now, their number is exploding. In just the past 2 years, the count has more than doubled, passing 60.

The streams are particularly useful for what astronomers call galactic archaeology—rewinding the cosmic clock to reconstruct the assembly of the Milky Way. They also are being used as exquisitely sensitive scales to measure the galaxy's mass. The third possible application for stellar streams is perhaps the most intriguing. Patrolling the outskirts of the galaxy's halo, the streams are well-positioned to reveal the presence of dark matter, the unseen stuff thought to dominate ordinary matter by a ratio of nearly six to one. Because the streams are so fragile, theorists say, collisions with marauding clumps of dark matter could leave telltale scars, potential clues to its nature.

The article is illustrated by the 2011 Cosmotography image capturing the incredibly faint rings of stellar rivers that surround galaxy NGC5907 for the first time.

Tidal Streams in the Local Group and Beyond

A New Book announces the publication of Tidal Streams in the Local Group and Beyond. The book includes a chapter, titled "Stellar Tidal Streams in External Galaxies", co-authored by Jeffrey L. Carlin, Rachael L. Beaton, David Martínez-Delgado and R. Jay GaBany.

According to the publisher: This book is written by leading scientists in the field, who review the current state of our knowledge of tidal streams in the Milky Way, the Andromeda galaxy, and in other nearby galaxies. The cosmological origins of dwarf galaxies and the physical processes by which they are tidally disrupted into streams and incorporated into galaxy halos are discussed. The techniques that have been used to identify tidal streams are presented and will be useful to researchers who would like to find substructures in the next generation of optical sky surveys, including Pan-STARRS and LSST.

The methods that are currently under development to constrain both large scale distribution of dark matter in the Milky Way and the (small scale) lumpiness of the dark matter distribution are also explained. The authors also provide motivation for future spectroscopic surveys of Milky Way halo stars, which will aid both in the identification of tidal streams and the constraint of dark matter properties.

This volume is aimed at graduate students who are beginning this field of research, but is also a resource for researchers who study tidal streams and related fields. In addition to presenting the physical processes by which tidal streams are created, it also reviews the current state of the observations and the progress towards utilizing these observations to constrain the distribution of dark matter in the Milky Way.

The book will introduce anyone with a background in astrophysics to the field of tidal streams.

Breakthrough-100 Astronomical Images that Changed the World

A New Book announces the publication of Breakthrough-100 Astronomical Images that Changed the World. Co-authored by R. Jay GaBany and noted astrophotographer Dr. Robert Gendler, the book explores the history of astrophotography through the lens of 100 ground breaking images that altered humanity’s perception of its place in the universe.

According to the publisher: This unique volume by two renowned astrophotographers unveils the science and history behind 100 of the most significant astronomical images of all time. The authors have carefully selected their list of images from across time and technology to bring to the reader the most relevant photographic images spanning all eras of modern astronomical history.

Based on scientific evidence today we have a basic notion of how Earth and the universe came to be. The road to this knowledge was paved with 175 years of astronomical images acquired by the coupling of two revolutionary technologies – the camera and telescope. With ingenuity and determination humankind would quickly embrace these technologies to tell the story of the cosmos and unravel its mysteries.

This book presents in pictures and words a photographic chronology of our aspiration to understand the universe. From the first fledgling attempts to photograph the Moon, planets, and stars to the marvels of orbiting observatories that record the cosmos at energies beyond the range of human vision, astronomers have always relied on images to "break through" to the next level of understanding. A subset of these breakthrough images has profound significance in documenting some of the greatest milestones in modern astronomy.

    "This is not a book about astrophoto techniques. Rather, the text describes the scientific background of each image, and so there is quite a lot of astronomical history to be read here. This is a really different and special book. I think anyone interested in how we got to know what we do about the universe will be a happy reader of this delightful volume. "

Merging Galaxies Illuminate the Cosmic Food Chain

(from the W. M. Keck Observatory web site) MAUNA KEA, HAWAII- Scientists studying a ‘twin’ of the Milky Way have used the W. M. Keck Observatory and Subaru Observatory to accurately model how it is swallowing another, smaller galaxy. Their findings have opened the way to a better understanding of how structure forms in the universe and are being published in the Monthly Notices of the Royal Astronomical Society this week.

The present work is a follow-up to a 2010 study, led by Dr. David Martínez-Delgado (University of Heidelberg), which used small robotic telescopes to image eight isolated spiral galaxies, and found the signs of mergers- shells, clouds and arcs of tidal debris- in six of them. Read more...

Distant ‘cannibal twin’ shows how galaxies grow

(from the Australian Astronomical Observatory web site) A distant ‘twin’ of the Milky Way that is swallowing another galaxy has opened the way to a better understanding of how galaxies grow.

A team led by Dr Caroline Foster of the Australian Astronomical Observatory (AAO) has been studying the Umbrella galaxy, so called because of its ‘parasol’ of stars- the remains of a smaller galaxy it’s consuming.

The Umbrella (NGC 4651) lies 62 million light-years away, in the northern constellation of Coma Berenices.

Twenty years ago, astronomers using AAT identified a new ‘dwarf’ galaxy, the Sagittarius dwarf, being engulfed by our own Milky Way Galaxy.

This was the first sign that the Milky Way had fattened up- acquired stars- by snacking on other, smaller, galaxies. Since then, astronomers have spotted stellar streams in other galaxies. Read more...

Swallowed by a Black Hole

Scientific collaboration featured on BBC2 Horizon Broadcast

Recent research into the core of the Perseus galaxy cluster conducted by Dr. Andrew C. Fabian ( Institute of Astronomy, University of Cambridge, UK) and an international team of astronomers has been featured in the 2013 BBC2 Horizon program titled "Swallowed by a Black Hole". A deep white light and narrowband image (left) of the Perseus galaxy cluster produced by and first released on was used in this research and featured in the BBC program (seen approximately 47:00 minutes into the program).

"Swallowed by a Black Hole" has also been in rotation on the Science Channel (USA).

About Swallowed by a Black Hole:
Duration: 59 minutes

Not so long ago, black holes were regarded as the destroyers of the universe: a dark force from which nothing escapes; only recently have we come to understand they may be a key part of a universe's creation.

During summer 2013, the black hole at the centre of the Milky Way is getting ready to feast.

A gas cloud three times the size of our planet has strayed within the gravitational reach of our nearest supermassive black hole. And across the globe, telescopes are being trained on the heart of our Milky Way galaxy, some 27,000 light years from Earth, in the expectation of observing this unique cosmic spectacle.

For cosmic detectives across the Earth, it is a unique opportunity. For the first time in the history of science, they hope to observe in action the awesome spectacle of a feeding supermassive black hole.

Parade Magazine Names Cosmotography Author One of the 10 Most Influential People in Space:

From the editor's at Parade:

R. Jay GaBany: Stellar Shutterbug

Gigantic observatories and orbiting space telescopes don’t own astronomy. Not entirely. Smaller can sometimes be better, as astrophotographer R. Jay GaBany has proven. The galactic mergers that produce spiral galaxies like the Milky Way leave behind faint relics called stellar tidal streams. But because these cosmic fossils are so large, viewing them requires wider views and longer exposure times than are possible at major observatories. With a half-meter telescope located under the dark skies in the mountains of New Mexico, GaBany patiently produces unmatched images of stellar streams. Though officially an amateur, GaBany collaborates with the pros as a peer, earning scientific respect and accolades in the process.

    NGC 5907 featured on cover of the journal Astronomy & Astrophysics, February 2012, vol. 538, A121

    Loops formed by tidal tails as fossil records of a major merger

    (from the Astronomy & Astrophysics press release) NGC 5907 is a spiral galaxy lying in the Dragon constellation, showing extraordinary large loops and currents of stars in its surrounding halo. According to researchers, it could have been formed through a gigantic collision of galaxies, 8 to 9 billion years ago. Six scientists of the Observatoire de Paris, CNRS, Chinese Academy of Sciences, National Astronomical Observatories of China and Aix-Marseille Université propose this scenario on the basis of simulations with 200,000 to 6 million particles.

Apparently, in a similar manner- through cosmic cannibalism. Two research groups including MPIA researchers David Martínez-Delgado and Michelle Collins from the Max Planck Institute for Astronomy in Heidelberg have found a mini galaxy which is just in the process of devouring another.

    (from the NAOJ web site) Research by an international team of scientists has revealed a "stealth merger" of dwarf galaxies, where an in-falling satellite galaxy is nearly undetectable by conventional means yet has a substantial influence on its host galaxy. The Subaru Telescope captured high-resolution images of individual stars in a dense stream of stars in the outer regions of a nearby dwarf galaxy (NGC 4449); these outlying stars are the remains of an even smaller companion galaxy in the process of merging with its host.

    Watching a tiny galaxy grow

    (from the Max-Planck Institute for Astronomy web site) For the first time, astronomers have caught a so-called dwarf galaxy in the process of swallowing another, even smaller galaxy. Whether such mergers are important for the evolution of the tiniest galaxies has been the subject of debate among theoreticians. Now, thanks to research by two independent groups including MPIA researchers David Martínez-Delgado and Michelle Collins, there is empirical evidence that such mergers occur. The analyses draw on deep images from modestly sized telescopes, in an example for successful collaboration between amateur and professional astronomers.

    Dwarfs gobbling dwarfs: a tidal star stream around NGC 4449

    We have mapped and analyzed a stellar stream in the halo of the nearby dwarf starburst galaxy NGC 4449, detecting it in deep integrated-light images using the Black Bird II Observatory 0.5-meter telescope, and resolving it into a river of individual red giant branch stars using the 8.2-meter Subaru/Suprime-Cam (NAOJ). The properties of the stream imply a massive dwarf spheroidal progenitor, which will continue to disrupt and deposit an amount of stellar mass that is comparable to the existing stellar halo of the main galaxy. The ratio between luminosity or stellar-mass between the two galaxies represents a stealth major merger. This singular discovery also suggests that satellite accretion can play a significant role in building up the stellar halos of low-mass galaxies, and possibly in triggering their starbursts.

    The formation of shell galaxies similar to NGC 7600 in the cold dark matter cosmogony

    A new N-body simulation, demostrates the continuous accretion of stars and dark matter clumps can create a swath of diffuse circumgalactic structures. The disruption of a massive near-radial orbiting dark matter clump creates a complex system of transient concentric shells which bare a striking resemblance to those observed surrounding NGC 7600. With the aid of the simulation we interpret NGC 7600 in the context of the CDM model.

    The objective of this exhibition is to present abroad the astrophysics investigation studies that are carried out in Spain, a country that counts important observatories in its territory, coinciding with the celebration of the Year International of Astronomy in 2009. Many of the most remarkable international observatories are in Spanish speaking countries: Chile, Mexico, Argentina, Venezuela and Spain, with the Roque de los muchachos observatory, (La Palma) and the Teide observatory (Tenerife) both belonging to the Institute of Astrophysics of the Canary Islands.

    These thirty spectacular astronomic photographs show planets, nebulas, galaxies, and stars, starting from a ‘scan’ of the universe from its beginning. The four stages of the journey are: up to the borders of the Milky Way; our galaxy, the Milky Way; the Solar System.

    Surprises of the Cosmos has been touring since April 2009, showing in various international branches of the Instituto Cervantes including those in Madrid, Lisbon, Beijing, Shanghai, Tokyo, Utrecht, London, New Delhi, Sydney.

    Two of my images are part of an exhibition. Included are NGC 5907 and NGC 891

    (from the Science website)To what extent are a galaxy's properties determined by its inner workings or through interactions with its surroundings? To solve that puzzle, some astronomers are searching for rare galaxies well isolated from their neighbors. By comparing these loners to their more-gregarious brethren, researchers hope to tease apart the inherent inner workings of galaxies and the effects of interactions. Last month, 120 researchers gathered in Granada, Spain, to discuss such efforts. Article by Adrian Cho

    Capturing the Stars: Astrophotography by the Masters (Hardcover)

    Book publication

    Several images have been published in a new book by master astrophotographer Robert Gendler. Images include:The Iris Nebula (my personal favorite picture), The Horsehead Nebula, The Crab Nebula and others. Robert included a short, but exceedingly generous, introduction to the section of this book featuring my collection of images.

    Book description: Galaxies, star clusters, nebulae, and other deep-sky treasures fill the pages of this beautiful volume of space photography from ten of the most accomplished astrophotographers in the world. Along with the marvels of the night sky--the Andromeda and Whirlpool galaxies, the Pleiades and the Praesepe, the Orion and Crab nebulae, and many more--each section features a profile of the photographer’s work, techniques, philosophy, and experiences. Compiled by the world's leading amateur astrophotographer, with an introduction to the history of space photography, this spectacular volume is an essential for every stargazer’s bookshelf.

    The Heavens Proclaim: Astronomy and the Vatican
    Book publication

    My image of NGC 5907 has been included in a new book by Guy Consolmagno that has been published by the Vatican Observatory Publications.

    For more than 100 years, the Vatican has supported an astronomical observatory. But that should come as no surprise; from even before the Gregorian Reform of the Calendar in 1582, indeed dating back to the invention of the University (where studying astronomy was a requirement for anyone wanting a doctorate in philosophy or theology!) the Church has not only supported astronomical has seen the study of the Heavens as a way of getting to know the Creator!

    In honor of the International Year of Astronomy, the Vatican and its Observatory is delighted to present this small expression of support, filled with beautiful images from the Vatican's telescopes and wisdom from the Popes, to show that indeed.

    Discover the Universe 2009- Norway
    Image Exhibition

    At the invitation of Jan-Erik Ovaldsen, the acclaimed Norwegian astrophysicist, author and astronomy evangelist, and with the permission of the Subaru Observatory on Maua Kea, Hawaii, I prepared an updated rendtion of the Subaru Deep Field image, produced several years ago for the Norwegian celebration of Discover the Universe 2009.

    So far, the Subaru Deep Field project has generated over thirty scientific papers. To the delight of the original research team, one of the earliest findings announced the identification of one of the farthest known galaxies- an early star system 12.88 billion light years from Earth!

    This rendition, plus one or two other pictures, are being displayed on oversized, outdoor posters with photographs from professional observatories, orbiting space telescopes and several other independent astrophotographers in Oslo, Norway, from April through June 2009, in Sandefjord, Norway from August 1- 31, 2009 and Kristiansand, Norway, from mid-June through October 31, 2009.

    Horsehead Makes Cover of Dickinson & Dyer's Third Edition

    The Backyard Astronomer's Guide

    This picture of the Horsehead Nebula was selected for the cover of Terence Dickinson & Alan Dyer's third edtion of the Backyard Astronomer's Guide.

    Sky & Telescope said: "Guide books for amateur astronomers abound, but none is more up to date than the heavily illustrated third edition of Terence Dickinson and Alan Dyer's The Backyard Astronomer's Guide. It's an indispensible aid for amateurs wading into the ocean of modern telescopes, eyepieces and accessories. And the section on astrophotography with digital cameras is among the finest we've seen..If you were to own only one book on amateur astronomy, this is it!"
