Temporal Evolution of the Radial Distribution of Milky Way Satellite Galaxies

Ekta Patel, Lipika Chatur, Yao-Yuan Mao

The Milky Way (MW) is surrounded by dozens of satellite galaxies, with six-dimensional (6D) phase space information measured for over 80% of this population. The spatial distributi…

SAGAbg II: the Low-Mass Star-Forming Sequence Evolves Significantly Between 0.05<z<0.21

Erin Kado-Fong, Marla Geha, Yao-Yuan Mao +8

The redshift-dependent relation between galaxy stellar mass and star formation rate (the Star-Forming Sequence, or SFS) is a key observational yardstick for galaxy assembly. We use…

Stellar Mass Calibrations for Local Low-Mass Galaxies

Mithi A. C. de los Reyes, Yasmeen Asali, Risa Wechsler +10

The stellar masses of galaxies are measured using integrated light via several methods -- however, few of these methods were designed for low-mass ($M_{\star}\lesssim10^{8}\rm{M_{\…
