The Rogue One: A Dark Matter-Dominated Dwarf in the Trail of Dark Matter-Deficient Galaxies

Daniel Vaz, Arsen Levitskiy, Duncan Forbes +6

We present the first measurement of the stellar velocity dispersion of LEDA 4014647, a compact dwarf galaxy spatially aligned with the NGC 1052 trail, a linear chain of dark matter…

AGC 322753: a Dark Galaxy Candidate detected by ALFALFA and FASHI

Marco Monaci, Duncan A. Forbes, Warrick J. Couch +1

We report the possible detection of a Dark Galaxy Candidate (DGC; AGC 322753), via the cross-matching of the Arecibo Legacy Fast ALFA (ALFALFA) and the FAST All Sky HI (FASHI) HI b…

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

Oğuzhan Çakır, 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…
