No Stream Left Unscathed: The imprint of a host galaxy
Arpit Arora, Peter S. Ferguson, Jacob Nibauer +11
Stellar streams from disrupted globular clusters are excellent probes of dark matter (DM) subhalos. Observed Milky Way streams display a remarkable diversity of features: spurs, ga…
The origin of strong -element bimodalities in FIRE simulations of Milky Way-mass galaxies
Megan Barry, Andrew Wetzel, Sarah Loebman +2
One of the Milky Way's characteristic features is a strongly bimodal distribution of -process elements, such as Mg, at fixed [Fe/H] in stellar abundances. We examine patterns in…
The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
Formation of Cosmic Noon Protogalaxies via Quasar-Induced Fragmentation of a Cosmic Filament
Marko Mićić, Themiya Nanayakkara, Xinyu Dai +2
When black hole jets encounter ambient medium, they can compress the gas, trigger star formation, and create stellar clusters containing tens of thousands of stars. Here, we report…
Stars Born in the Wind: M82's Outflow and Halo Star Formation
Vaishnav V. Rao, Adam Smercina, Eric F. Bell +8
Starburst galaxies, like M82, launch kiloparsec-scale galactic outflows that interact with the circumgalactic medium (CGM) in complex ways. Apart from enriching the CGM with metals…
Spiral Structure Properties, Dynamics, and Evolution in MW-mass Galaxy Simulations
J. R. Quinn, S. R. Loebman, K. J. Daniel +8
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain. Two challe…
