Dr. Jonathan Stern, Tel Aviv University

I am a Senior Lecturer [equivalent to Assistant Prof.] in the Astrophysics Department of Tel Aviv University, studying physical processes related to the formation of galaxies.

I am actively searching for students and postdocs. I am happy to talk with interested applicants at any time. 

I am also happy to give public lectures for non-professional audiences (see Talks below). Please email me if you would like to organize such an event.

Jonathan Stern


My research focuses on the physics of gas in dark matter halos, known as the circumgalactic medium (CGM), and how it interacts with the galaxy at the center of the halo. The CGM constitutes the immediate environment of the galaxy, so physical processes in the CGM have a paramount effect on galaxy formation and evolution.


I use a wide range of tools in my work, including analytic derivations from first principles, hydrodynamic simulations including both idealized setups and fully-cosmological calculations, and inference from observations. 

I also study the surroundings of massive black holes in the center of galaxies (with masses of millions to billions times the Sun mass), and how the physical process in these regions affect galaxy evolution, a process known as 'quasar feedback'.


I am part of the FIRE galaxy simulations collaboration. I'm also involved in projects together with Drummond Fielding (CCA), Claude-Andre Faucher-Giguere and his group at Northwestern University, James Bullock and his group at UC Irvine, Eliot Quataert (Princeton), Sean D. Johnson (UMich), Joe Hennawi (Leiden), Jorg-Uwe pott (MPIA), J. X. Prochaska (UC Santa Cruz), Jose Onorbe (Univ. of Seville), Amiel Sternberg (Tel Aviv), and the Line Emission Mapper (LEM) X-ray probe science working group.
