A New Model for the Milky Way Halo Dispersion Measure with the ENGAWA Simulations: Low DMs and Large Anisotropy
Scott Lucchini, Liam Connor, Samuel McCarty +1
Fast radio burst (FRB) dispersion measures (DMs) are powerful tracers of the low density universe, but interpretation is made difficult by the integrated nature of DM. In this pape…
The LMC Corona Favors a First Passage
Scott Lucchini, Jiwon Jesse Han, Sapna Mishra +1
We use constrained idealized simulations of the LMC/Milky Way interaction to determine if the size of the LMC's gaseous halo (Corona) can be used to distinguish between first and s…
Threading the Magellanic Needle: Hypervelocity Stars Trace the Past Location of the LMC
Scott Lucchini, Jiwon Jesse Han
Recent discoveries have shown that a population of hypervelocity stars (HVSs) originate from the Large Magellanic Cloud (LMC). We use three such HVSs as dynamical tracers to constr…
ENhanced Galactic Atmospheres With Arepo: Resolving the CGM at 200 pc with the ENGAWA Simulations
Scott Lucchini, Cecilia Abramson, Cameron Hummels +3
Simulating the small-scale features and dynamics of the circumgalactic medium (CGM) is computationally challenging due to its large volume, low densities, multiphase structure, and…
A Pre-Infall Magellanic Analog-Corona and Stream formation in the \textsc{HESTIA} cosmological simulations
Robin Chisholm, Elena D'Onghia, Noam Libeskind +3
We identify and investigate a pre-infall analog of the Large and Small Magellanic Clouds (LMC, SMC) in the HESTIA suite of constrained cosmological simulations. The system, dynamic…
New Interpretation for the Orientation of the LMC's Gaseous Arms B and E using ULLYSES
April Horton, Suraj Poudel, Kathleen A. Barger +20
The Large Magellanic Cloud (LMC) experiences disruption from tidal and ram-pressure forces as it travels through the halo of the Milky Way. In this project, we combine radio emissi…
