The REFLEX Galaxy Cluster Survey IV: The X-ray Luminosity Function
The X-ray galaxy cluster sample from the REFLEX Cluster Survey, which covers the X-ray brightest galaxy clusters detected in the ROSAT All-Sky Survey in the southern sky, is used to construct the X-ray luminosity function of clusters in the local Universe. With 452 clusters detected above an X-ray flux-limit of 3 · 10 erg s cm in 4.24 sr of the sky, this sample is the most comprehensive X-ray c...
متن کاملThe REFLEX galaxy cluster survey . VIII . Spectroscopic observations and optical atlas ⋆
We present the final data from the spectroscopic survey of the ROSAT-ESO Flux-Limited X-ray (REFLEX) catalog of galaxy clusters. The REFLEX survey covers 4.24 steradians (34% of the entire sky) below a declination of δ = +2.5 and at high Galactic latitude (|b| > 20◦). The REFLEX catalog includes 447 entries with a median redshift of 0.08 and is better than 90% complete to a limiting flux fX = 3...
متن کاملThe XMM Cluster Survey : A Massive Galaxy
We report the discovery of XMMXCS J2215.9-1738, a massive galaxy cluster at z = 1.45, which was found in the XMM Cluster Survey. The cluster candidate was initially identified as an extended X-ray source in archival XMM data. Optical spectroscopy shows that 6 galaxies within a ∼60 arcsec diameter region lie at z = 1.45 ± 0.01. Model fits to the X-ray spectra of the extended emission yield kT = ...
