A mass threshold for galactic gas discs by spin flips
Avishai Dekel, Omri Ginzburg, Fangzhou Jiang +4
We predict, analytically and by simulations, that gas discs tend to survive only in haloes above a threshold mass (stellar mass )…
A model for core formation in dark matter haloes and ultra diffuse galaxies by outflow episodes
Jonathan Freundlich, Avishai Dekel, Fangzhou Jiang +5
We present a simple model for the response of a dissipationless spherical system to an instantaneous mass change at its center, describing the formation of flat cores in dark matte…
Multi-Filament Inflows Fueling Young Star Forming Galaxies
D. Christopher Martin, Donal O'Sullivan, Mateusz Matuszweski +13
Theory suggests that there are two primary modes of accretion through which dark matter halos acquire the gas to form and fuel galaxies, hot and cold mode accretion. In cold mode a…
Origin of the Golden Mass of Galaxies and Black Holes
Avishai Dekel, Sharon Lapiner, Yohan Dubois
We address the origin of the golden mass and time for galaxy formation and the onset of rapid black-hole growth. The preferred dark-halo mass of ~ is translated to…
