Personal Overview

Dr. Perlman is an observational astrophysicist whose research concentrates on the nuclei of galaxies, their physics and evolution, particularly those in which the central black hole has a large rate of accretion and is abnormally active (the so-called active galactic nuclei). He also specializes in the structure and physics of high-velocity outflows from compact objects and AGN, particularly, jets. He also has a strong interest in clusters of galaxies, galactic activity in clusters and observational cosmology. He takes a multiwaveband approach to these subjects, and has worked in virtually every energy range from the radio through gamma-rays.

Dr. Perlman was awarded 5-year NASA Long-Term Space Astrophysics Program grants in 2000 and 2005, and is a member of the AGN science team for CanariCam, a first-light instrument for the Gran Telescopio Canarias, currently the largest ground-based optical/infrared telescope. He is a frequent user of the Hubble Space Telescope, Chandra X-ray Observatory and other orbiting telescopes.

Dr. Perlman came to FIT in 2007 after postdoctoral fellowships at Goddard Space Flight Center and the Space Telescope Science Institute, as well as research staff and research faculty positions at the Johns Hopkins University and the University of Maryland, Baltimore County. He maintains a large research group that includes a postdoctoral fellow as well as typically 3-4 graduate students and an equal number of undergraduate research assistants. In his spare time, he enjoys chess, singing, scrabble, playing with his kids, reading, photography, and working out.

My research spans several areas of astrophysics, and my contributions in each have been strong, well cited and diverse. His main area of expertise is in the field of high-energy astrophysics, specifically the physics of active galaxies, where I have made important contributions to our knowledge of jets, the high-energy, relativistic flows that emerge from the central regions of the most powerful AGN. I have made critical contributions to the physical processes responsible for their emission, their response to stimuli and variability, and also made available a database of these objects on the WWW. I have in the process received over $2,000,000 in grants, including two 5-year NASA Long-Term Space Astrophysics Program grant, a 3-year NSF grant, and multiple smaller grants for observations with the Hubble Space Telescope and Chandra X-ray

Observatory. I have also done ground-breaking work on cosmology, including work at the very edge of physics and astrophysics, laying out the geometry and framework for tests of quantum gravity using astronomical observations of the most distant quasars, and on the distribution of clusters of galaxies in the local and distant universe. I have parlayed these important accomplishments into two large chapters in graduate-level textbooks on extragalactic astrophysics, published during the last two years.
