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…
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,…
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…
The extended globular cluster system of the archetypal "failed galaxy" Dragonfly-44 from deep white-light Hubble Space Telescope imaging
Maria Luisa Buzzo, Pieter van Dokkum, Roberto Abraham +2
For nearly a decade, Dragonfly-44 (DF44, ) has been considered an archetypal ``failed galaxy'', a system so rich in globular clusters (GCs)…
New Measurements of Distances to Galaxies in the NGC 1052 Field with the Hubble and James Webb Space Telescopes: Testing the Bullet-Dwarf Origin of the Trail
Yimeng Tang, Gagandeep S. Anand, Aaron J. Romanowsky +2
NGC 1052-DF2 and DF4 are two ultra-diffuse galaxies deficient in dark matter (DM), and reported as part of a remarkable linear trail of dwarf galaxies in the NGC 1052 field. Recent…
Dark matter-deficient twins: FCC 224 and FCC 240 as possible analogues of NGC 1052-DF2 and DF4
Maria Luisa Buzzo, Pieter van Dokkum, Michael Hilker +3
The recent "bullet-dwarf" model proposes that high-velocity collisions between dwarf galaxies can produce stellar systems with overluminous globular clusters (GCs) and a deficiency…
