Summary
Joshua Simon Bloom (born June 8, 1974, Washington, D.C.) is an American astrophysicist and associate professor of astronomy at the University of California, Berkeley. He received a Bachelor of Arts in astronomy and astrophysics and physics from the Harvard College in 1996, an M.Phil from Cambridge University in 1997, and a Ph.D. in astronomy from the California Institute of Technology in 2002. He was a Junior Fellow of the Harvard Society of Fellows from 2002 to 2005. His research focuses on gamma-ray bursts and other astrophysical transients such as supernovae. He is author of the book What Are Gamma-Ray Bursts? published by Princeton University Press in 2011.
In 2009, ScienceWatch wrote that Bloom's gamma-ray bursts "work ranks at #10 by total cites, based on 85 papers cited a total of 3,639 times. Five of these papers are on the lists of the 20 most-cited papers over the past decade and over the past two years.". He has published over 150 refereed articles and is principal investigator of the Peters Automated Infrared Telescope (PAIRITEL) at the Fred Lawrence Whipple Observatory in Arizona. He is also principal investigator of the Synoptic Infrared Survey Telescope (SASIR). Project and is currently co-chair of the transients and variable star group of the Large Synoptic Survey Telescope (LSST). Some of Bloom's current work focuses on the classification of astrophysical transients using machine-learning techniques.
Bloom was awarded the Herchel Smith Harvard Scholarship to Cambridge University in 1996, and was a Hertz Foundation Fellow at the California Institute of Technology. In 2004, Bloom was named as a Sloan Research Fellow by the Alfred P. Sloan Foundation. In 2008, he was included as one of Astronomy magazine's ten "rising stars. In 2009, he was awarded the Newton Lacy Pierce Prize in Astronomy from the American Astronomical Society. In 2010, he was named as the Sophie and Tycho Brahe Visiting Professor at Copenhagen University. He is the creator of the VOEvent messaging scheme for astronomical transients.

Toward an Understanding of the Progenitors of Gamma-Ray BurstsThe various possibilities for the origin ("progenitors") of gamma-ray bursts (GRBs) manifest in differing observable properties. Through deep spectroscopic and high-resolution imaging... |
