We use high-resolution N-body/smoothed particle hydrodynamic simulations to study the hydrodynamical and gravitational interaction between the Large Magellanic Cloud (LMC) and the Milky Way Galaxy. We model the dark and hot extended halo components as well as the stellar/gaseous discs of the two galaxies. Both galaxies are embedded in extended cuspy �CDM dark matter haloes. We follow the previous 4 Gyr of the LMC’s orbit such that it ends up with the correct location and orientation on the sky. Tidal forces elongate the LMC’s disc, forcing a bar and creating a strong warp and diffuse stellar halo, although very few stars become unbound. The stellar halo may account for some of the microlensing events observed towards the LMC. Ram pressure from a low-density ionized halo is then sufficient to remove

SIMULATIONS OF THE MAGELLANIC STREAM IN A FIRST INFALL SCENARIO (2010, background): “This indicates that hydrodynamic processes such as ram pressure (Mastropietro et al. 2005) are needed to shape the final appearance of the simulated stream.”
Gaseous Galaxy Halos (2012, background): “…System and it is thought to be the result of a combination of a tidal interaction between the two satellites and their subsequent interaction with the Milky Way (Connors et al., 2006b; Mastropietro et al., 2005; Besla et al., 2010; Gardiner, 1999; Diaz & Bekki, 2012; Nidever et al., 2008).”
Hunting for the Dark Matter Wake Induced by the Large Magellanic Cloud (2019, background): “The gaseous MS is subject to hydrodynamical forces such as gas drag and ram pressure (Mastropietro et al. 2005), owing to its motion through the Circumgalactic Medium (CGM), which may create offsets (e.g. Roediger & Brüggen 2006).”
