Gas and stellar dynamics in Stephan’s Quintet

Stephan's Quintet (SQ) is a nearby compact galaxy group and perfect laboratory for studying the process of evolution through harassment interaction. By analysing kinematics SQ we aim to provide an increased understanding group, history interactions, their cause effect, details regarding physical processes occurring as galaxies interact. We have studied ionised gas stellar using Large Binocular Telescope, molecular via CO IRAM 30m. areas been mapped analysed. obtain total mass in regions chosen closer analysis 20.1$\pm$0.2x10^10 Msun H2 21$\pm$2x10^9 observed area (spectra integrated over velocity range SQ), while star-forming (SF) clouds show impressive complexity, with congregations at multiple velocities throughout group. map large-scale nuclear wind NGC7319 its decoupled disk.
