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…
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''…
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…
Analysis of Galaxies at the Extremes: Failed Galaxy Progenitors in the MAGNETICUM Simulations
Jonah S. Gannon, Lucas C. Kimmig, Duncan A. Forbes +5
There is increasing observational evidence for a failed galaxy formation pathway for some ultradiffuse galaxies (UDGs) at low redshift however they currently lack simulated counter…
Do Ultra-Diffuse Galaxies Follow the Globular Cluster-Halo Mass Relation?
Duncan A. Forbes, Jonah S. Gannon
The stellar mass-halo mass relation and the globular cluster (GC) number-halo mass relation are two scaling relations that relate fundamental properties of normal galaxies. Ultra-D…
Dot to dot: high- little red dots in - diagrams with galaxy-morphology-specific scaling relations
Alister W. Graham, Igor V. Chilingarian, Dieu D. Nguyen +3
The high redshift 'little red dots' (LRDs) detected with the James Webb Space Telescope are considered to be the cores of emerging galaxies that host active galactic nuclei (AGN).…
WALLABY Pilot Survey: the Tully-Fisher relation in the NGC 4808, Vela and NGC 5044 fields
Jeremy Mould, T. H. Jarrett, Hélène Courtois +18
The Tully-Fisher Relation (TFR) is a well-known empirical relationship between the luminosity of a spiral galaxy and its circular velocity, allowing us to estimate redshift indepen…
Science Cases for the Keck Wide-Field Imager
J. Cooke, C. Angus, K. Auchettl +22
The Keck Wide-Field Imager (KWFI) is a proposed 1-degree diameter field of view UV-sensitive optical camera for Keck prime focus. KWFI will be the most powerful optical wide-field…
