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…
Bypassed Core Formation in Milky Way-Mass SIDM Halos: Implications for the Local Group Past-Pericenter Scenario
Zhichao Carton Zeng, Odelia V. Hartl, Louis E. Strigari +4
We consider a scenario in which the Milky Way (MW) and M31 have had a previous pericentric passage, and investigate its compatibility with self-interacting dark matter (SIDM). Usin…
The Merian Survey: A Statistical Census of Bright Satellites of Milky Way Analogs
Yue Pan, Shany Danieli, Jenny E. Greene +10
We present a statistical census of bright, star-forming satellite galaxies around Milky Way (MW) analogs using the first data release of the Merian Survey. Our sample consists of 3…
Dwarf diversity in CDM with baryons
Akaxia Cruz, Alyson Brooks, Mariangela Lisanti +7
Observed rotation curves of dwarf galaxies exhibit significant diversity at fixed halo mass, challenging galaxy formation within the Cold Dark Matter (CDM) model. Previous cosmolog…
Diversity and universality: evolution of dwarf galaxies with self-interacting dark matter
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +4
Dark matter halos with self-interacting dark matter (SIDM) experience a unique evolutionary phenomenon, in that their central regions eventually collapse to high density through th…
