Simulation data + processed quantities for the isolated and wind cases of the Large Magellanic Cloud

We used the GIZMO-MHD code to create a simulation of the Large Magellanic Cloud with two scenarios - an isolated galaxy and a galaxy passing through the circumgalactic medium of the Milky Way and experiencing ram pressure stripping as a result of the Milky Way wind. Our mass resolution is 250 solar masses (for the medhighres cases), which is one of the best out there for galaxy simulations containing magnetic fields. While the entire simulation runs over 500 Myr astrophysical timescales, we only upload the final snapshot from both scenarios as they should be equivalent to the present-day LMC. We upload processed quantities, which account for varied radiation background at different places in the interstellar medium, and tools to calculate mock quantities like rotation measures. We also attach one snapshot + processed quantities at low resolution (called medres) for testing.

Significance Statement
This is the first simulation of a dwarf galaxy called the Large Magellanic Cloud that includes magnetic fields. The work has been accepted in a prestigious journal, Monthly Notices of the Royal Astronomical Society. All the authors of this paper are from the Research School of Astronomy and Astrophysics, ANU.
Brief Description
Two snapshots + corresponding processed quantities of the simulation of LMC - isolated case and wind case at high resolution (medhighres in snapshot name). One snapshot + corresponding processed quantities of the LMC simulation at low resolution (called medres) for testing.
