ADC_Keywords: Clusters, galaxy ; X-ray sources ; Redshifts Keywords: galaxies: clusters: general - large-scale structure of universe - X-rays: galaxies: clusters Abstract: We present the latest results of the Clusters in the Zone of Avoidance (CIZA) survey, which is mapping large-scale structures behind the Milky Way by performing the first systematic search for galaxy clusters at low Galactic latitudes. The survey's approach, which uses X-ray emission to locate cluster candidates, minimizes the problems faced by optically selected cluster surveys, which have traditionally avoided this region of the sky due to the severe extinction present along the Galactic plane. We here present the second flux-limited CIZA cluster catalog, containing 57 X-ray-selected galaxy clusters, of which 88% are new discoveries. We use this sample to examine the degree to which known large-scale structures extend into the zone of avoidance and highlight newly discovered structures that have previously gone unnoticed. Description: The CIZA survey is the first systematic search for X-ray-luminous galaxy clusters behind the Galactic plane. File Summary:
