Astrophysics at The University of Haifa

 
 

Astrophysics at the University of Haifa is about three years old. Our research interests are quite diverse within the field of astrophysics and astro-particle physics. More specifically, we mix theory and observations to try and tackle fundamental (astro-) physical problems concerning the nature of dark matter, the growth of supermassive black holes over cosmic time, and the formation and evolution of star-forming galaxies. We are also interested in “gastrophysics“ and attempt to understand the properties of dilute plasma under extreme astrophysical conditions. More information about our projects may be found by following the relevant links above.


Our group collaborates with people at other universities in Israel (e.g., the Technion and TAU), and abroad (e.g., Princeton University). The theoretical tools of the “trade” are analytical (pen and paper) and numerical (computer) models. For our work we often use data from telescopes around the world, such as the Apache Point Observatory, Subaru, and the Wise observatory, as well as from space observatories such as the Hubble Space Telescope, GALEX, and Chandra.


We are currently seeking new members to join our group either at the graduate (towards the Ph.D. degree) student level, or at the postdoctoral level. For inquiries please feel free to contact Doron Chelouche at

Welcome to our group...

The few images above are broadly related to our science. Left: the Rosette nebula. Top right: 3D dark matter mapping of a volume in the universe. Lower left: a pair of star-forming interacting galaxies. Lower right: a cartoon of the space curvature near a black hole.

Our research is partially supported by:

June 2013: We show that standard accretion disk physics provides a good description for the engine underlying nuclear activity in active galaxies. Specifically, using reverberation mapping we show that the mass accretion rates onto the supermassive black hole are consistent with indendent expectations. These results indicate that photometric surveys can provide unique constraints on accretion disk physics in active galactic nuclei and quasars. See Chelouche (2013).

May 2013: We formulate a new method for reverberation mapping that is applicable to spectroscopic, and photometric (both narrow- and broad-band) data, and is able to shed light on the physics of the accretion disk and the broad line region in active galactic nuclei. For more information see Chelouche & Zucker (2013).
