Spectroscopic Confirmation of a Coma Cluster Progenitor at z ~ 2.2
Behnam Darvish, Nick Z. Scoville, Christopher Martin +17
We report the spectroscopic confirmation of a new protocluster in the COSMOS field at 2.2, COSMOS Cluster 2.2 (CC2.2), originally identified as an overdensity of narrowb…
The Dark Matter Distributions in Low-Mass Disk Galaxies. II. The Inner Density Profiles
Nicole C. Relatores, Andrew B. Newman, Joshua D. Simon +8
Dark matter-only simulations predict that dark matter halos have steep, cuspy inner density profiles, while observations of dwarf galaxies find a range of inner slopes that are oft…
The FLASHES Survey I: Integral Field Spectroscopy of the CGM around 48 QSOs
Donal O'Sullivan, Christopher Martin, Mateusz Matuszewski +5
We present the pilot study component of the Fluorescent Lyman-Alpha Structures in High-z Environments (FLASHES) Survey; the largest integral-field spectroscopy survey to date of th…
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…
The Dark Matter Distributions in Low-Mass Disk Galaxies. I. H Observations Using the Palomar Cosmic Web Imager
Nicole C. Relatores, Andrew B. Newman, Joshua D. Simon +6
Dark-matter-only simulations predict that dark matter halos have cusp-like inner density profiles, while observations of low-mass galaxies have found a range of inner slopes that a…
