Diffuse Dwarf Galaxies in Galaxy Clusters: I. Stellar Populations and Radial Gradients
Arsen Levitskiy, Duncan A. Forbes, Jonah S. Gannon +5
We use Keck/KCWI spectroscopy to study one ultra-diffuse galaxy (UDG) and five Nearly-UDGs (NUDGEs) in the Perseus cluster, together with an additional UDG in the Coma cluster. As…
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…
FAST and Dark: A catalogue of Dark Galaxy Candidates within 50 Mpc
Marco Monaci, Duncan A. Forbes, Jonah S. Gannon +4
Using the first data release of the Five-hundred-meter Aperture Spherical radio Telescope (FAST) All-Sky HI survey (FASHI), we compile a catalogue of 70 dark galaxy candidates (DGC…
The SAMI Galaxy Survey: Quenching of Star Formation in Clusters III. Ram-Pressure-Affected Galaxy Populations
OÄuzhan Ãakır, Matt S. Owers, Luca Cortese +15
Cluster environments influence galaxy evolution by curtailing star formation activity, notably through ram-pressure stripping (RPS). In this study, using spatially resolved spectro…
Ultra-Diffuse, Ultra-Different: Observed vs. Simulated Ultra-Diffuse Galaxies Live in Fundamentally Different Halos
Jonah S. Gannon, Arianna Di Cintio, Duncan A. Forbes +5
In this work, we compare galaxies from the NIHAO and HESTIA simulation suites to ultra-diffuse galaxies (UDGs) with spectroscopically measured dynamical masses. For each observed U…
The Impact of Cluster Mergers on Galaxy Properties
OÄuzhan Ãakır, Matt S. Owers, Lucas C. Kimmig +4
The impact of galaxy cluster mergers on the properties of the resident galaxies remains poorly understood. In this paper, we investigate the effects of merging environments on star…
