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…
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,…
FIREBall-2: advancing TRL while doing proof-of-concept astrophysics on a suborbital platform
Erika T. Hamden, Keri Hoadley, D. Christopher Martin +32
Here we discuss advances in UV technology over the last decade, with an emphasis on photon counting, low noise, high efficiency detectors in sub-orbital programs. We focus on the u…
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…
Discovery of a Lya emitting dark-cloud within z ~ 2.8 SMMJ02399-0136 system
Qiong Li, Zheng Cai, J. Xavier Prochaska +9
We present Keck/KCWI integral field spectrograph observations of the complex system surrounding SMM J023990136 (a lensed sub-mm galaxy), including an associated Ly$\rm α…
