"The RomulusC Simulation: Exploring Galaxy Evolution in Clusters at Unprecedented Resolution"
I present results from the RomulusC cosmological zoom-in simulation of a 10^14 Msun galaxy cluster. With 10^5 Msun and 250pc mass and spatial resolution resepectively, this is one of the highest resolution simulations of a galaxy cluster ever completed. RomulusC can resolve multiphase structure in the intracluster medium, as well as dwarf galaxies down to stellar masses of 10^7 Msun. I discuss recent and current work being done with RomulusC to understand galaxy evolution in dense environments: 1) the evolution of the brightest cluster galaxy and the role of AGN feedback in regulating and quenching star formation, 2) how the evolution of cluster member galaxies and their SMBHs are affected by their extreme environment, and 3) the first self-consistent prediction for the origin of ultra-diffuse galaxies in clusters.
