Unveiling the largest structures in the nearby Universe: Discovery of the Quipu superstructure
Hans Boehringer, Gayoung Chon, Joachim Truemper +2
For a precise determination of cosmological parameters we need to understand the effects of the local large-scale structure of the Universe on the measurements. They include modifi…
The Cosmic Large-Scale Structure in X-rays (CLASSIX) Cluster Survey III: The Perseus-Pisces supercluster and the Southern Great Wall as traced by X-ray luminous galaxy clusters
Hans Boehringer, Gayoung Chon, Joachim Truemper
The Perseus-Pisces supercluster is known as one of the largest structures in the nearby Universe that has been charted by the galaxy and galaxy cluster distributions. For the latte…
The Cosmic Large-Scale Structure in X-rays (CLASSIX) Cluster Survey II: Unveiling a pancake structure with a 100 Mpc radius in the local Universe
Hans Boehringer, Gayoung Chon, Joachim Truemper
Previous studies of the galaxy and galaxy cluster distribution in the local Universe found indications for a large extension of the Local Supercluster up to a radius of 190 h_70^-1…
The 3D soft X-ray cluster-AGN cross-correlation function in the ROSAT NEP survey
N. Cappelluti, H. Boehringer, P. Schuecker +4
X-ray surveys facilitate investigations of the environment of AGNs. Deep Chandra observations revealed that the AGNs source surface density rises near clusters of galaxies. The nat…
Spatial Correlation Function of X-ray Selected AGN
C. R. Mullis, J. P. Henry, I. M. Gioia +4
We present a detailed description of the first direct measurement of the spatial correlation function of X-ray selected AGN. This result is based on an X-ray flux-limited sample of…
Detection of X-ray Clusters of Galaxies by Matching RASS Photons and SDSS Galaxies within GAVO
Peter Schuecker, Hans Boehringer, Wolfgang Voges
A new method for a simultaneous search for clusters of galaxies in X-ray photon maps and optical galaxy maps is described. The merging of X-ray and optical data improves the source…
