MARVELously Dark: the density profile evolution of dwarf halos in velocity-dependent SIDM
Anna Engelhardt, Ferah Munshi, Annika H. G. Peter +6
Self-interacting dark matter (SIDM) with a sufficiently large cross section has been shown to naturally produce constant dark matter (DM) cores, as well as core-collapse, at the ce…
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…
The Seven Dwarfs illuminated. The impact of radiation on dwarf galaxies and their circumgalactic medium
Bernhard Baumschlager, Sijing Shen, James W. Wadsley +6
We present a high-resolution cosmological zoom-in simulation of a group of field dwarf galaxies which includes on-the-fly radiative transfer (RT) and is evolved to . Emission…
Survivors and Zombies: The Quenching and Disruption of Satellites around Milky Way Analogs
Debosmita Pathak, Charlotte R. Christensen, Alyson M. Brooks +3
It is necessary to understand the full accretion history of the Milky Way in order to contextualize the properties of observed Milky Way satellite galaxies and the stellar halo. Th…
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 Merger-Driven Formation of Classical Low Surface Brightness Galaxies in Romulus25
Anna C. Wright, Alyson M. Brooks, Michael Tremmel +3
We use the Romulus25 cosmological simulation volume to study a large sample of late-type gas-rich galaxies with low central surface brightnesses known as classical low surface brig…
