Is the Milky Way ringing? The hunt for high-velocity streams
We perform numerical simulations of a stellar galactic disc with initial conditions chosen to represent an unrelaxed population which might have been left following a merger. Stars are unevenly distributed in radial action angle, though the disc is axisymmetric. The velocity distribution in the simulated solar neighbourhood exhibits waves travelling in the direction of positive ν, where u, ν are the radial and tangential velocity components. As the system relaxes and structure wraps in phase...[Show more]
