Discovery and Characterization of Two Ultra Faint-Dwarfs Outside the Halo of the Milky Way: Leo M and Leo K
Kristen B. W. McQuinn, Yao-Yuan Mao, Erik J. Tollerud +4
We report the discovery of two ultra-faint dwarf galaxies, Leo M and Leo K, that lie outside the halo of the Milky Way. Using Hubble Space Telescope imaging of the resolved stars,…
The Influence of Subhaloes on Host Halo Properties
Lorena Mezini, Catherine E. Fielder, Andrew R. Zentner +3
Within the CDM cosmology, dark matter haloes are comprised of both a smooth component and a population of smaller, gravitationally bound subhaloes. These components are often tr…
Pegasus W: An Ultra-Faint Dwarf Galaxy Outside the Halo of M31 Not Quenched by Reionization
Kristen. B. W. McQuinn, Yao-Yuan Mao, Matthew R. Buckley +3
We report the discovery of an ultrafaint dwarf (UFD) galaxy, Pegasus W, located on the far side of the Milky Way-M31 system and outside the virial radius of M31. The distance to th…
Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao +39
We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift ta…
Evidence of Galaxy Assembly Bias in SDSS DR7 Galaxy Samples from Count Statistics
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +4
We present observational constraints on the galaxy-halo connection, focusing particularly on galaxy assembly bias, from a novel combination of counts-in-cylinders statistics, $P(N_…
Extending the SAGA Survey (xSAGA) I: Satellite Radial Profiles as a Function of Host Galaxy Properties
John F. Wu, J. E. G. Peek, Erik J. Tollerud +6
We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low- galaxies on the basis of optical imaging, and results on the spatial…
