Morphologies of SAGAbg low-mass galaxies in Legacy Survey multi-band imaging: dependence on stellar masses, star-formation rates and low-redshift evolution

Joy Bhattacharyya, Guinevere Herron, Yasmeen Asali +4

The optical morphologies of low-mass galaxies can be used to directly trace their assembly and constrain models of galaxy evolution. We select a sample of 6211 low-mass ($7\lesssim…

Trends with Mass for Dwarf Galaxies from the Marvelous Massive Dwarfs Suite

Dilys Ruan, Alyson M. Brooks, Leonardo A. Barba +7

Galaxy formation scenarios can be interpreted through galaxy morphology and the level of rotational versus pressure support, quantified through the ratio of a galaxy's rotation spe…

SAGAbg III: Environmental Stellar Mass Functions, Self-Quenching, and the Stellar-to-Halo Mass Relation in the Dwarf Galaxy Regime

Erin Kado-Fong, Yao-Yuan Mao, Yasmeen Asali +8

Recent efforts have extended our view of the number and properties of satellite galaxies beyond the Local Group firmly down to . A similarly complete…

The SAGA Survey. VI. The Size-Mass Relation for Low-Mass Galaxies Across Environments

Yasmeen Asali, Marla Geha, Erin Kado-Fong +10

We investigate how Milky Way-like environments influence the sizes and structural properties of low-mass galaxies by comparing satellites of Milky Way analogs from the Satellites A…

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_{\…

The SAGA Survey. V. Modeling Satellite Systems around Milky Way-mass Galaxies with Updated UniverseMachine

Yunchong Wang, Ethan O. Nadler, Yao-Yuan Mao +11

Environment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the UniverseMachine (UM) galaxy-halo connection framework and the Data Release 3 of the…
