Extreme Obscuration and Circumnuclear Star-Formation Revealed in AGN NGC 4968
Abstract
NGC 4968 is a nearby (z=0.00986) Seyfert 2 galaxy which has X-ray signatures of heavy obscuration. From a recent Chandra observation, we discovered extended thermal emission on ~1 kpc scales, emanating from hot gas (kT ~ 0.7 keV) associated with star-formation. We measure an extreme Fe Kα equivalent width (EW) of 2.4 keV, which is an indication that the source is completely enshrouded in Compton-thick material. We highlight that other Type 2 AGN with extreme Fe Kα EWs also have on-going circumnuclear star-formation. We posit that in these systems gas associated with star-formation may provide material for the obscuring medium around the AGN.
