Astrophysics at The University of Haifa
Astrophysics at the University of Haifa is only about two 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.
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.

Our research is partially supported by:
June 2012: We measure the black hole mass of the least massive supermassive black hole to date, that of NGC4395, using the photometric reverberation mapping of Chelouche & Daniel (2012). The data were acquired by the Wise Observatory, and lead to a refined mass estimate for NGC4395 of ~50,000 solar masses. For more information see Edri et al.
May 2012: We measure the black hole mass in a luminous, high-z quasar using the photometric reverberation mapping method of Chelouche & Daniel (2012). The black hole mass is found to be ~1 billion solar masses, and as such, is the most massive black hole ever measured in a radio-quiet quasar using the reverberation mapping technique.
