Turbulent molecular gas and star formation in the shocked intergalactic medium of Stephan's Quintet
Pierre Guillard, François Boulanger, Guillaume Pineau des Forêts +8
We report on single-dish radio CO observations towards the inter-galactic medium (IGM) of the Stephan's Quintet (SQ) group of galaxies. Extremely bright mid-IR H2 rotational line e…
Detection of Powerful Mid-IR H2 Emission in the Bridge between the Taffy Galaxies
B. W. Peterson, P. N. Appleton, G. Helou +6
We report the detection of strong, resolved emission from warm H2 in the Taffy galaxies and bridge. Relative to the continuum and faint PAH emission, the H2 emission is the stronge…
Strong molecular hydrogen emission and kinematics of the multiphase gas in radio galaxies with fast jet-driven outflows
Pierre Guillard, Patrick Ogle, Bjorn Emonts +6
Observations of ionized and neutral gas outflows in radio-galaxies (RGs) suggest that AGN radio jet feedback has a galaxy-scale impact on the host ISM, but it is still unclear how…
