Clusters in the Zone of Avoidance
Abstract
The Clusters in the Zone of Avoidance (CIZA) project is producing the first statistically complete catalogue of X-ray selected galaxy clusters behind the Galactic plane. Current optically selected cluster catalogues have excluded a wide band of sky centered on the Milky Way (|b| < 20 deg) due to the high extinction and stellar obscuration at low Galactic latitudes. An X-ray search for cluster candidates overcomes the problems faced by optically selected catalogues, hence providing the first opportunity to explore the sky in the traditional Zone of Avoidance; principally, the Great Attractor region. When added to other X-ray selected cluster surveys such as the BCS and REFLEX, CIZA will complete the first unbiased, all-sky cluster catalogue. We here report on the progress of the CIZA survey as well as preliminary results of a dipole analysis which utilizes the current CIZA sample.
