The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters

Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3

Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…

Effects of Varied Cosmic Ray Feedback from AGN on Massive Galaxy Properties

Charvi Goyal, Sam B. Ponnada, Philip F. Hopkins +3

Active galactic nuclei (AGN) provide energetic feedback necessary to `turn off' star formation in high-mass galaxies (M 10 M, $10.4 \leq \log(…

The Environmental Quenching Mechanisms of Field Dwarf Galaxies

José A. Benavides, Julio F. Navarro, Laura V. Sales +2

Field dwarf galaxies not actively forming stars are relatively rare in the local Universe, but are present in cosmological hydrodynamical simulations. We use the TNG50 simulation t…

Effects of galactic environment on size and dark matter content in low-mass galaxies

Francisco J. Mercado, Jorge Moreno, Robert Feldmann +8

We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,…

Size-Mass Relations for Simulated Low-Mass Galaxies: Mock Imaging versus Intrinsic Properties

Courtney Klein, James S. Bullock, Jorge Moreno +4

The observationally-inferred size versus stellar-mass relationship (SMR) for low-mass galaxies provides an important test for galaxy formation models. However, the relationship rel…
