Formation of globular cluster-rich ultra-diffuse galaxies through mergers
Truman Tapia, Hidenori Matsui, Kenji Bekki +6
We use high-resolution, idealized hydrodynamic simulations of gas-rich dwarf-galaxy mergers to test whether such encounters can form ultra-diffuse galaxies (UDGs) with globular clu…
Merger Driven or Internal Evolution? A New Morphological Study of Tidal Disruption Event Host Galaxies
Janet N. Y. Chang, Connor Bottrell, Lixin Dai +7
The host galaxies of tidal disruption events (TDEs) show enhanced central stellar concentration and are preferentially found in poststarburst and green valley populations. This con…
ERGO-ML: The assembly histories of HSC galaxy images via invertible neural networks, contrastive learning, and cosmological simulations
Lukas Eisert, Connor Bottrell, Annalisa Pillepich +4
In this paper of ERGO-ML (Extracting Reality from Galaxy Observables with Machine Learning), we develop a model that infers the merger/assembly histories of galaxies directly from…
Interacting galaxies in the IllustrisTNG simulations - IX: Mini mergers trigger AGN in cosmological simulations
Shoshannah Byrne-Mamahit, Sara L. Ellison, David R. Patton +3
Galaxy mergers are transformative events that can cause gaseous inflows capable of triggering active galactic nuclei (AGN). Previous studies of AGN in simulations have mainly focus…
The connection between galaxy mergers, star formation and AGN activity in the HSC-SSP
Kiyoaki Christopher Omori, Connor Bottrell, Sabine Bellstedt +6
Internal gas inflows driven by galaxy mergers are considered to enhance star formation rates (SFR), fuel supermassive black hole growth and stimulate active galactic nuclei (AGN).…
