Disentangling satellite galaxy populations using orbit tracking in simulations

28 Jan 2013Kyle A. OmanMichael J. HudsonPeter S. Behroozi

Physical processes regulating star formation in satellite galaxies represent an area of ongoing research, but the projected nature of observed coordinates makes separating different populations of satellites (with different processes at work) difficult. The orbital history of a satellite galaxy leads to its present-day phase space coordinates; we can also work backwards and use these coordinates to statistically infer information about the orbital history...
