NIR identification of z~1 clusters detected in the X-ray by XMM



Left: PN (XMM) X-ray image. Right SOFI K band image of one of the extedend X-ray sources barely seen on I (CFHT) and z' (CTIO) deep images and detected in the K band.
Violet ellipse shows the X-ray detection.

Mosaic of the 9 NIR confirmed clusters, i.e. of the 9 extended X-ray sources showing  a spatially coincident  statistically significant galaxy overdensity.
Each panel is about 1x1 arcmin wide. X-ray wavelet filtered contours are shown in blue. "missing" X-ray contours will come soon.
