The role played by active galactic nuclei (AGN) in the evolution of galaxiesfrom an actively star-forming state to quiescence is still poorly understood.Post- starburst galaxies, particularly those caught early in their transition,provide an important testing ground for examining this question. There are hintsthat a large fraction of post-starburst galaxies may contain AGN or AGN-drivenactivity. We undertook a 10ks snapshot survey of 12 post-starburst galaxies withChandra and detected X-ray emission in 9 of the 12 observed. However, these datahave in- sufficient counts to determine the nature of this emission anddistinguish between AGN and thermal emission. We propose to observe two of themost interesting galaxies from this sample in order to characterize their nuclear emission.

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.
