Appleton, P N; Xu, Kevin C; Reach, William; Dopita, Michael; Gao, Y; Lu, N; Popescu, Cristina C; Sulentic, J W; Tuffs, Richard J; Yun, M S


We present the discovery of strong mid-infrared emission lines of molecular hydrogen of apparently high-velocity dispersion (∼870 km s -1) originating from a group-wide shock wave in Stephan's Quintet. These Spitzer Space Telescope observations reveal e
