An extremely metal-deficient globular cluster in the Andromeda Galaxy
S. S. Larsen, A. J. Romanowsky, J. P. Brodie +1
Globular clusters (GCs) are dense, gravitationally bound systems of thousands to millions of stars. They are preferentially associated with the oldest components of galaxies, and m…
How Accurately Can We Detect the Splashback Radius of Dark Matter Halos and its Correlation With Accretion Rate?
Enia Xhakaj, Benedikt Diemer, Alexie Leauthaud +5
The splashback radius () of dark matter halos has recently been detected using weak gravitational lensing and cross-correlations with galaxies. However, different metho…
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…
A Deficit of Dark Matter from Jeans Modeling of the Ultra-diffuse Galaxy NGC 1052-DF2
Asher Wasserman, Aaron J. Romanowsky, Jean Brodie +5
The discovery of the ultra-diffuse galaxy NGC 1052-DF2 and its peculiar population of star clusters has raised new questions about the connections between galaxies and dark matter…
The Dragonfly Nearby Galaxies Survey. V. HST/ACS Observations of 23 Low Surface Brightness Objects in the Fields of NGC1052, NGC1084, M96, and NGC4258
Yotam Cohen, Pieter van Dokkum, Shany Danieli +8
We present HST/ACS imaging of twenty-three very low surface brightness (=25-27.5) galaxies detected in the fields of four nearby galaxy groups. These objects were selected…
