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.
