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…
