RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
Pisces VII/Triangulum III -- M33's second dwarf satellite galaxy
Michelle L. M. Collins, Noushin Karim, David Martinez-Delgado +6
Pisces VII/Triangulum III (Pisc~VII) was discovered in the DESI Legacy Imaging Survey and was shown to be a Local Group dwarf galaxy with follow-up imaging from the 4-m Telescopio…
Andromeda XXV -- a dwarf galaxy with a low central dark matter density
Emily J. E. Charles, Michelle L. M. Collins, R. Michael Rich +7
Andromeda (And) XXV has previously been reported as a dwarf spheroidal galaxy (dSph) with little-to-no dark matter. However, the uncertainties on this result were significant. In t…
A detailed star formation history for the extremely diffuse Andromeda XIX dwarf galaxy
Michelle L. M. Collins, Benjamin F. Williams, Erik J. Tollerud +3
We present deep imaging of the ultra-diffuse Andromeda XIX dwarf galaxy from the Advance Camera for Surveys on the Hubble Space Telescope which resolves its stellar populations to…
Six More Ultra-Faint Milky Way Companions Discovered in the DECam Local Volume Exploration Survey
W. Cerny, C. E. Martínez-Vázquez, A. Drlica-Wagner +28
We report the discovery of six ultra-faint Milky Way satellites discovered through matched-filter searches conducted using Dark Energy Camera (DECam) data processed as part of the…
The Hubble Space Telescope Survey of M31 Satellite Galaxies I. RR Lyrae-based Distances and Refined 3D Geometric Structure
Alessandro Savino, Daniel R. Weisz, Evan D. Skillman +33
We measure homogeneous distances to M31 and 38 associated stellar systems (16.8 6.0), using time-series observations of RR Lyrae stars taken as part of the Hubbl…
