Dark Energy Survey Year 1 Results: Methods for Cluster Cosmology and Application to the SDSS
M. Costanzi, E. Rozo, M. Simet +83
We perform the first blind analysis of cluster abundance data. Specifically, we derive cosmological constraints from the abundance and weak-lensing signal of \redmapper\ clusters o…
The XXL Survey XX: The 365 cluster catalogue
C. Adami, P. Giles, E. Koulouridis +54
In the currently debated context of using clusters of galaxies as cosmological probes, the need for well-defined cluster samples is critical. The XXL Survey has been specifically d…
The XXL Survey XXV. Cosmological analysis of the C1 cluster number counts
F. Pacaud, M. Pierre, J. -B. Melin +25
Context. We present an estimation of cosmological parameters with clusters of galaxies. Aims. We constrain the , , and parameters from a stand-alone sample of X-ray c…
The XXL survey XXXV. The role of cluster mass in AGN activity
E. Koulouridis, M. Ricci, P. Giles +15
We present the results of a study of the AGN density in a homogeneous and well-studied sample of 167 bona fide X-ray galaxy clusters () from the XXL Survey. The results…
The XXL Survey: XXXIII. Chandra Constraints on the AGN Contamination of z > 1 XXL Galaxy Clusters
C. H. A. Logan, B. J. Maughan, M. N. Bremer +11
Context. The XMM-XXL survey uses observations from XMM-Newton to detect clusters of galaxies over a wide range in mass and redshift. The moderate PSF of XMM-Newton means that point…
Chandra Follow-Up of the SDSS DR8 redMaPPer Catalog Using the MATCha Pipeline
Devon L. Hollowood, Tesla Jeltema, Xinyi Chen +15
In order to place constraints on cosmology through optical surveys of galaxy clusters, one must first understand the properties of those clusters. To this end, we introduce the Mas…
The XXL Survey: XXX. Characterisation of the XLSSsC N01 supercluster and analysis of the galaxy stellar populations
V. Guglielmo, B. M. Poggianti, B. Vulcani +34
Superclusters form from the largest enhancements in the primordial density perturbation field and extend for tens of Mpc, tracing the large-scale structure of the Universe. We char…
The Cluster Survey: joint modelling of the scaling relation for clusters and groups of galaxies
Leyla Ebrahimpour, Pedro T. P. Viana, Maria Manolopoulou +16
We characterize the X-ray luminosity--temperature () relation using a sample of 353 clusters and groups of galaxies with temperatures in excess of 1 keV, spanning the…
Correlations between X-ray properties and Black Hole Mass in AGN: towards a new method to estimate black hole mass from short exposure X-ray observations
Julian A. Mayers, Kathy Romer, Arya Fahari +14
Several investigations of the X-ray variability of active galactic nuclei (AGN) using the normalised excess variance () parameter have shown that variability has a…
