Distance Estimation using Globular Clusters and Ultra-Compact Dwarfs
Bas van Heumen, Jonah S. Gannon, Duncan A. Forbes +2
The tight scaling relation between absolute magnitude and internal velocity dispersion () for globular clusters (GCs), referred to as the GC velocity dispersion (GCVD) relation,…
The Stellar Populations of Two Quiescent Low Surface Brightness Dwarf Galaxies in Low Density Environments
Duncan A. Forbes, Hannah S. Christie, Arsen Levitskiy +3
Dwarf galaxies located in low density environments that have quiescent stellar populations are extremely rare and the mechanism for quenching their stars is highly uncertain. Here…
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…
MATLAS-42, A Globular Cluster-Rich Ultra-Diffuse Galaxy That Diverges from the "Failed Galaxy'' Formation Pathway
Jonah S. Gannon, Duncan A. Forbes, Francine R. Marleau +4
To date, there has been significant interest in globular cluster (GC)-rich ultra-diffuse galaxies (UDGs) and the evidence that they have formed via an unexpected, ``failed galaxy''…
