LOCATION:  Comal 212

PRESENTER:  Dr. Blagoy Rangelov


Title: Machine-Learning Methods in Astrophysics: Unveiling the X-ray Universe



Pulsars and black holes are among the most exotic objects in the Universe. These compact sources have such extreme environments that cannot be reproduced here on Earth. Pulsars and black holes are often found in binary systems, and have such a strong gravitational pull that it strips matter from the companion star, a process so violent that can be detected across the electromagnetic spectrum from radio wavelengths all the way to X-rays and even gamma-rays. While many compact objects have been discovered (either isolated or in binaries), source classification remains a laborious task. Fast and reliable identification of astrophysical sources will be a major challenge in the near future, as data streams from new survey facilities will be measured in Terabytes (and very soon Petabytes) per year. The enormous amount of information that has been accumulated in catalogs remains largely unexploited because most of the cataloged sources are not classified into astrophysical source categories. Modern machine-learning methods can be used to analyze the vast amount of data for these unclassified sources in a very short time providing both the classifications and their confidence.


Blagoy Rangelov received a B.S. degree in Physics from Sofia University, Bulgaria, where, a year later, he graduated with a M.S. degree in Astronomy and Astrophysics. In 2006 he joined the Ph.D. program of the Department of Physics and Astronomy at the University of Toledo, where he worked on extragalactic astronomy. Blagoy Rangelov broadened his knowledge and skill set by becoming a Pre-doctoral Fellow at the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA. There he had the excellent opportunity to carry out research in extragalactic high-energy astrophysics and gained hands-on experience in using modern X-ray telescopes and their data analysis. In 2013 he became a Postdoctoral Scientist at the George Washington University, where he conducted research in galactic and extragalactic high-energy astrophysics. In the Fall of 2016, Blagoy Rangelov joined the Department of Physics at Texas State University.
