Virgo Cluster of Galaxies

Description

A composite of X-ray (blue) emission from the core of the Virgo Cluster as observed with the IPC of the Einstein Observatory and total hydrogen maps of the 10 brightest spirals as observed with the VLA in its most compact D-array configuration (red contours). The X-ray image is a mosaic of many individual non-overlapping observations with a square imaging camera, which leads to the irregular appearence in the image. The angular scale of the individual total HI maps has been magnified with a factor of 11. The anticorrelation between the X-ray emission and neutral hydrogen makes it likely that the HI-deficient spirals have been stripped by the hot X-ray halo of M87, a bright elliptical near the center of the cluster and a bright X-ray source, corresponding to the bright source at the center of the image.
The VLA was in the D-array configuration.
