Halo Contraction Effect in Hydrodynamic Simulations of Galaxy Formation

Oleg Y. Gnedin, Daniel Ceverino, Nickolay Y. Gnedin +5

The condensation of gas and stars in the inner regions of dark matter halos leads to a more concentrated dark matter distribution. While this effect is based on simple gravitationa…

Measuring Gas Accretion and Angular Momentum near Simulated Supermassive Black Holes

Robyn Levine, Nickolay Y. Gnedin, Andrew J. S. Hamilton

Using cosmological simulations with a dynamic range in excess of 10 million, we study the transport of gas mass and angular momentum through the circumnuclear region of a disk gala…

Resolving Gas Dynamics in the Circumnuclear Region of a Disk Galaxy in a Cosmological Simulation

Robyn Levine, Nickolay Y. Gnedin, Andrew J. S. Hamilton +1

Using a hydrodynamic adaptive mesh refinement code, we simulate the growth and evolution of a galaxy, which could potentially host a supermassive black hole, within a cosmological…

AGN Outflows and the Matter Power Spectrum

Robyn Levine, Nickolay Y. Gnedin

We have investigated the effects of AGN outflows on the amplitude of the matter power spectrum in a simple model of spherically symmetric outflows around realistically clustered AG…

AGN Outflows in a Cosmological Context

Robyn Levine, Nickolay Y. Gnedin

We combine cosmological simulations with an AGN luminosity function constrained by optical surveys in order to create a realistic AGN distribution in which to model AGN outflows. T…
