New Constraints on Early-Type Galaxy Assembly from Spectroscopic Metallicities of Globular Clusters in M87
Alexa Villaume, Aaron J. Romanowsky, Jean Brodie +1
The observed characteristics of globular cluster (GC) systems, such as metallicity distributions, are commonly used to place constraints on galaxy formation models. However, obtain…
Spatially Resolved Stellar Kinematics of the Ultra-Diffuse Galaxy Dragonfly 44: II. Constraints on Fuzzy Dark Matter
Asher Wasserman, Pieter van Dokkum, Aaron J. Romanowsky +9
Given the absence of directly detected dark matter (DM) as weakly interacting massive particles, there is strong interest in the possibility that DM is an ultra-light scalar field,…
Spatially-resolved stellar kinematics of the ultra diffuse galaxy Dragonfly 44. I. Observations, kinematics, and cold dark matter halo fits
Pieter van Dokkum, Asher Wasserman, Shany Danieli +8
We present spatially-resolved stellar kinematics of the well-studied ultra diffuse galaxy (UDG) Dragonfly 44, as determined from 25.3 hrs of observations with the Keck Cosmic Web I…
Extreme chemical abundance ratio suggesting an exotic origin for an ultra-diffuse galaxy
Ignacio Martin-Navarro, Aaron J. Romanowsky, Jean P. Brodie +7
Ultra diffuse galaxies are a population of extended galaxies but with relatively low luminosities. The origin of these objects remains unclear, largely due to the observational cha…
