The Role of Dark Matter in Driving Disk Perturbations: Application to LMC-SMC Like Galaxy Interactions
Himansh Rathore, Hayden R. Foote, Gurtina Besla +6
Dark-matter (DM) models predict that satellite galaxies distort their host's DM halo. As such, both the satellite and the distorted halo can perturb the host's stellar disk. The LM…
A Statistical Framework to Identify Kinematically Outlying LMC Globular Clusters and Implications for the LMC's Dark Matter Profile
Tamojeet Roychowdhury, Navdha, Himansh Rathore +1
The LMC's Globular Clusters (GCs) bring a novel opportunity to understand the LMC's assembly history and dark matter (DM) properties, provided the kinematically outlying GCs can be…
Mapping the Distorted Dark Matter Distribution of the LMC-SMC System Prior to Milky Way Infall with Basis Function Expansions
Hayden R. Foote, Himansh Rathore, Gurtina Besla +6
The SMC orbits within the LMC's dark matter (DM) halo in a 1:10 mass-ratio encounter. The LMC:Milky Way (MW) interaction is also 1:10, and is expected to perturb the MW…
A Galactic Transformation -- Understanding the SMC's Structural and Kinematic Disequilibrium
Himansh Rathore, Gurtina Besla, Roeland P. van der Marel +1
The SMC is in disequilibrium. Gas line-of-sight (LoS) velocity maps show a gradient of km s, generally interpreted as a rotating gas disk consistent with the Tully-…
Response of the LMC's Bar to a Recent SMC Collision and Implications for the SMC's Dark Matter Profile
Himansh Rathore, Gurtina Besla, Kathryne J. Daniel +1
The LMC's stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies,…
Precise Measurements of the LMC Bar's Geometry With Gaia DR3 and a Novel Solution to Crowding Induced Incompleteness in Star Counting
Himansh Rathore, Yumi Choi, Knut A. G. Olsen +1
We present new measurements of the two-dimensional (2-D) geometry of the LMC's stellar bar with precise astrometric observations of red clump stars in Gaia DR3. We develop a novel…
