Extragalactic Stellar Streams in Time-Dependent Cosmological Halos

Sarah Pearson, Jacob Nibauer, Emily C. Cunningham +4

Upcoming and ongoing surveys will detect thousands of stellar streams around galaxies other than the Milky Way. Studies from the Milky Way have shown that time-dependent evolution…

Mergers Matter: Gravothermal Collapse in Dwarf Halos with Self-Interacting Dark Matter

Maya Silverman, Abdelaziz Hussein, Arpit Arora +8

Self-Interacting Dark Matter (SIDM) models with large cross sections at relative velocities below can be tested with dwarf galaxy observations. We ana…

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…

Probing Atomic Dark Matter with Stellar Streams in Milky Way-Mass Galaxies

Lucas S. Mandacarú Guerra, Stephanie O'Neil, Mariangela Lisanti +7

We present the first detailed analysis of the effects of dissipative dark matter on stellar streams. As a concrete example, we generate a cosmological hydrodynamic zoom-in simulati…

Kinematic Signatures in the Stellar Halo from Cosmological Encounters between the Milky Way and its Clouds

Mia Mansfield, Robyn Sanderson, Daniel Hey +4

Recent theoretical and observational analysis of the interaction between the Milky Way (MW) and LMC suggest that it has a significant dynamical impact on the MW's stellar halo. We…

The dark matter wake of a galactic bar revealed by multichannel Singular Spectral Analysis

Jason A. S. Hunt, Michael S. Petersen, Martin D. Weinberg +7

The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and thro…
