AGN-driven gas outflows in Stephan’s Quintet

David Law and Travis Fischer

Stephan’s Quintet is a well known example of interacting galaxies, whose tidal interactions trigger large scale gas flows. These gas flows have been revealed in spectacular detail by recent observations from the James Webb Space Telescope, from galaxy-scale molecular gas arcs to high-powered outflows driven by the AGN in the center of NGC 7319. We will discuss the multi-wavelength evidence for highly ionized outflows driven by this AGN through a surrounding molecular gas reservoir, and a preliminary analysis of the kinematics of this complex system.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
