SPH Simulations of Stephan's Quintet

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

We present smoothed particle hydrodynamic models of the interactions in the compact galaxy group, Stephan's Quintet. Adding thermohydrodynamic effects to the earlier collisionless N-body simulations of Renaud et al., we further investigate the dynamical interaction history and evolution of the intergalactic gas of Stephan's Quintet. Specifically, we reproduce the major stellar and gas features of the group and also model the formation of the hot X-ray gas, the group-wide shock, and emission line gas as the result of NGC 7318b colliding with the group. We compare our model results to multi-wavelength observations.
