New scientific collaboration submitted to the Astrophysical Journal Letters
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.

New scientific collaboration published in the Astrophysical Journal Letters
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.

Instituto Cervantes, Madrid, Spain
Image exhibition
Surprises of the Cosmos
The Instituto Cervantes presents the spectacular images of the project Surprises of the Cosmos.
The exhibition, organized by the Institute of Astrophysics of the Canary Islands, the Canary Government and the Instituto Cervantes, includes spectacular large format photographs showing planets, nebulas, galaxies and stars, starting from a ‘scan’ of the universe from its beginning.
The opening will take place the 22nd of July, at 6:30 pm, and will include a brief presentation of the exhibition held by Annia Domènech, journalist in science and curator of the project Surprises of the Cosmos.
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 |

The Tales Told by Lonely Galaxies
This image of NGC 5907 has been featured in the journal Science..
(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 research...it 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!"
