The Impact of Simulation Resolution on Dwarf Galaxy Stellar Stream Populations in FIRE
Yasmine J. Meziani, Nondh Panithanpaisal, Robyn E. Sanderson +4
Cosmological simulations allow us to study galaxy-progenitor stream populations, allowing comparisons with observations to constrain galaxy formation physics. Previous work found t…
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…
The Milky Way's Missing In-Situ Halo
Madeline Lucey, Robyn E. Sanderson, Alexander H. Riley +3
The Milky Way's stellar halo preserves a record of its mass assembly history, encoding accretion events in its structural properties. Among the most prominent of these features is…
The Dynamics of Old Inner Galaxy Stars in Milky Way-mass Galaxies Using FIRE-2 Simulations
Emma Tasso, Madeline Lucey, Robyn Sanderson +2
Understanding how galaxies like the Milky Way assembled over cosmic time remains a central question in astrophysics. Understanding the processes that shaped their formation and evo…
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…
Self-consistent dynamical modelling of the Milky Way bar with orbital frequency analysis
Zachary Langford, Robyn Sanderson, Madeline Lucey +1
We present an update to the frequency analysis method for measuring the properties of a galactic bar. The method involves computing the fundamental frequencies of orbits in rotatin…
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…
A near field guide to Roman's wide-area surveys
Robyn E. Sanderson, Kevin A. McKinnon, Adrien C. R. Thob +7
The Nancy Grace Roman Space Telescope currently plans to survey nearly 6000 square degrees of the sky, mainly in the High-Latitude Wide-Area Survey (HLWAS) and Galactic Plane Surve…
Modeling Globular Cluster Stellar Streams with a Basis-Expansion N-body Code
Brian T. Cook, Kerwann Tep, Carl L. Rodriguez +6
Globular cluster stellar streams probe galaxy-formation processes and can potentially reveal the distribution of dark matter in galaxies. In many theoretical studies, streams are m…
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…
