The remarkable X-ray morphology of the elliptical galaxy NGC4636 is best explained as resulting from strong shocks driven by a powerful, ( 6 X 10^{56} ergs) and recent ( 3 million years ago) outburst from the nucleus. We propose a deep ACIS-S observation, that along with our deep VLA observation, will allow us to explore the effects of AGN outbursts on cooling. At a distance of 15 Mpc, NGC4636 offers an opportunity to study the feedback between cooling flows and AGN in detail. By mapping the strength of the shock fronts and tracing them to large radii, we will constrain the nature of the outburst. To test recent models in which AGN outbursts transport cool gas back to large radii, we will map the temperature and distribution of heavy elements on a few arcseconds scales in the galaxy core.
