A Comprehensive Look at PUDG-R21: Stellar Population and Kinematics of a Globular Cluster-Rich Ultra-Diffuse Galaxy in the Perseus Cluster
Arsen Levitskiy, Duncan A. Forbes, Jonah S. Gannon +5
We present the analysis of the stellar populations and kinematics of the globular cluster (GC) rich ultra-diffuse galaxy, PUDG-R21, using spectroscopic observations obtained with t…
Radial velocities and stellar populations for a sample of MATLAS survey dwarfs
Kate Southon, Jonah S. Gannon, Duncan A. Forbes +4
Spectroscopic observations are essential for confirming associations, measuring kinematics, and determining stellar populations in dwarf galaxies. Here, we present Keck Cosmic Web…
An Unexplained Origin for the Unusual Globular Cluster System in the Ultra-diffuse Galaxy FCC 224
Yimeng Tang, Aaron J. Romanowsky, Jonah S. Gannon +9
We study the quiescent ultra-diffuse galaxy FCC 224 in the Fornax cluster using Hubble Space Telescope (HST) imaging, motivated by peculiar properties of its globular cluster (GC)…
Signs of `Everything Everywhere All At Once' formation in low surface brightness globular cluster-rich dwarf galaxies
Anna Ferré-Mateu, Jonah Gannon, Duncan A. Forbes +3
Only two ultra-diffuse galaxies (UDGs) have spatially resolved stellar population properties, both showing radially flat-to-rising metallicity profiles, indicative of a different f…
Why do some Ultra Diffuse Galaxies have Rich Globular Cluster Systems?
Duncan A. Forbes, Maria Luisa Buzzo, Anna Ferre-Mateu +4
Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system (M$_{…
The multiple classes of ultra-diffuse galaxies: Can we tell them apart?
Maria Luisa Buzzo, Duncan A. Forbes, Thomas H. Jarrett +9
This study compiles stellar populations and internal properties of ultra-diffuse galaxies (UDGs) to highlight correlations with their local environment, globular cluster (GC) richn…
