The Formation of Ultra-Diffuse Galaxies in the RomulusC Galaxy Cluster Simulation

By Michael Tremmel and others
We study the origins of 122 ultra-diffuse galaxies (UDGs) in the {\sc RomulusC} zoom-in cosmological simulation of a galaxy cluster (M200=1.15×1014_{200} = 1.15\times10^{14} M_{\odot}), one of the only such simulations capable of resolving the evolution and structure of dwarf galaxies (M<109_{\star} < 10^9 M_{\odot}). We find broad agreement with observed... Show more
