Dr. Jonathan Stern studies accreting massive black holes at the centers of galaxies (‘quasars’), the effect of quasars on their host galaxy (‘feedback’), and the extremely diffuse medium which surrounds galaxies such as the Milky-Way (the ‘circumgalactic-medium’ or ‘CGM’). In his work he tries to combine physical insights provided from analytic theory, idealized radiative-hydrodynamic simulations, full-blown cosmological simulations, and direct inference from observations. Much of his work is focused on the interaction of strong quasar radiation with surrounding interstellar gas, and on understanding the interplay of cooling flows and galaxy feedback in the CGM. He mainly collaborates with the galaxy formation group at Northwestern.
He was a CIERA post-doctoral fellow 2017-2020. Dr. Jonathan Stern now has a faculty position in the Department of Astrophysics at Tel-Aviv University.
