X-ray properties of quiescent post starburst galaxies with AGN-driven winds

We discovered a new class of spectrum which is the combination of poststarburst(E+A) galaxies and type II AGN. This may be the longsought link between ULIRGsand the quenching of star formation by AGN feedback, leading to red sequencegalaxies. We identified 24 such sources showing signatures of 0.20.7 Gyrstarbursts that were quenched abruptly. They all show AGNdriven winds with massoutflow rates of 2200 Msun/yr. Being the first sample of this type, the Xrayproperties are unknown. We propose XMMNewton observations of six of the sourcesfor which 1D and IFU spectroscopy will be available soon. The Xray data will beused to study the obscuring column of the torus and/or the outflowing material,and to compare with Xray properties of ULIRGs and type II AGN without ionized winds. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
