We discovered a new class of spectrum which is the combination of post-starburst(E+A) galaxies and type II AGN. This may be the long-sought link between ULIRGsand the quenching of star formation by AGN feedback, leading to red sequencegalaxies. We identified 24 such sources showing signatures of 0.2-0.7 Gyrstarbursts that were quenched abruptly. They all show AGN-driven winds with massoutflow rates of 2-200 Msun/yr. Being the first sample of this type, the X-rayproperties are unknown. We propose XMM-Newton observations of six of the sourcesfor which 1D and IFU spectroscopy will be available soon. The X-ray data will beused to study the obscuring column of the torus and/or the outflowing material,and to compare with X-ray properties of ULIRGs and type II AGN without ionized winds.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
