[1.02] The Chandra Fornax Survey

C. A. Scharf (Columbia University), D. Zurek (American Museum of Natural History), M. Bureau (Columbia University)

The Chandra Fornax Survey comprises of a mosaic of ten Chandra fields covering the inner 1 degree of the Fornax galaxy cluster, totaling 0.5 Msec of exposure time. At a distance of 20 Mpc, X-ray structure in Fornax is resolvable to 100pc scales. Over seven hundred X-ray sources have been resolved in the data, at least 200-300 of which likely inhabit the cluster and include dwarf galaxies, intra-cluster globular clusters and an array of other objects. Emission and temperature maps clearly show infalling galaxies, and a remarkably asymmetric ``swept back" cluster emission and distribution of X-ray active member galaxies. We describe many of the key results and argue that Fornax itself is experiencing an ``intergalactic wind'' as it coalesces with a known galaxy group falling inwards from 1 Mpc away.
