Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations
Ruxin Barré, Arif Babul, Ghassem Gozaliasl +7
We investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: ROMULUS, SIMBA, SIMBA-C, and…
Bright [CII]158m Streamers as a Beacon for Giant Galaxy Formation in SPT234956 at
Nikolaus Sulzenauer, Axel WeiÃ, Ryley Hill +17
Observations of extreme starbursts, often located in the cores of protoclusters, challenge the classical bottom-up galaxy formation paradigm. Giant elliptical galaxies at mus…
AGN Feedback Models and AGN Demographics I: Radio-Mode AGN in EAGLE, SIMBA and TNG100 are Inconsistent with Observations
Arjun Suresh, Michael R. Blanton, Douglas Rennehan
We compare predictions of how Active Galactic Nuclei (AGN) populate host galaxies at low redshifts to observations, finding large discrepancies between cosmological simulation pred…
Diverse dark matter profiles in FIRE dwarfs: black holes, cosmic rays and the cusp-core enigma
Sophie Koudmani, Douglas Rennehan, Rachel S. Somerville +5
Dwarf galaxies have historically posed challenges to the cold dark matter (CDM) model and, while many of the so-called 'dwarf galaxy problems' have been mitigated by incorporating…
Core to Cosmic Edge: SIMBA-C's New Take on Abundance Profiles in the Intragroup Medium at z = 0
Aviv Padawer-Blatt, Zhiwei Shao, Renier T. Hough +9
We employ the SIMBA-C cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM). W…
The Nature and Evolution of Early Massive Quenched Galaxies in the Simba-C Simulation
Jakub Szpila, Romeel Davé, Douglas Rennehan +2
We examine the nature, origin, and fate of early () massive () quenched galaxies (EQGs) in a new run of the Simba-C galaxy…
