The Disturbed Outer Milky Way Disc

Summer Project (2021)

Simulation of a Milky Way-like galaxy being perturb by a Sagittarius-like dwarf galaxy impact (represented by a point particle).

Supervisor: Paul McMillan
Project Description: In Gaia Early Data Release 3, a break in the vertical angular momentum-velocity plane can be disguished (Gaia Collaboration et al., 2021), a break that is suspected to have a dynamical origin. As part of my summer project, I explore the possibility for a dynamical origin by conducting a series of N-body simulations of a Milky Way-like galaxy being perturb by a Sagittarius-like dwarf galaxy impact using the RAMSES code (Teyssier, 2002).
