Identification of low redshift groups and clusters of galaxies in the X-CLASS survey and the X-ray luminosity-temperature relation
Q. Moysan, F. Sarron, N. Clerc +16
Properties of the hot intracluster and intragroup medium are mostly set by the underlying gravitational potential well, although complex astrophysical processes at play during thei…
The XXL Survey LIV. X-ray Luminosity Function and Luminosity-Mass Relation of Optically Selected Galaxy Groups
C. Wood, B. J. Maughan, J. P. Crossett +10
The overlap between the GAMA spectroscopic survey and the XXL X-ray survey was used to study the X-ray properties of optically-selected groups of galaxies. Forced X-ray aperture ph…
The active CGCG 077-102 NED02 galaxy within the Abell 2063 galaxy cluster
C. Adami, K. Parra Ramos, J. T. Harry +3
Within the framework of investigating the link between central super massive black holes in the core of galaxies and the galaxies themselves, we detected a variable X-ray source in…
The XXL survey: XLVI. Forward cosmological analysis of the C1 cluster sample
Christian Garrel, Marguerite Pierre, Patrick Valageas +15
We present the forward cosmological analysis of an selected sample of galaxy clusters out to a redshift of unity. Following our previous 2018 study based on the dn/dz quantit…
The X-CLASS survey: A catalogue of 1646 X-ray-selected galaxy clusters up to z1.5
E. Koulouridis, N. Clerc, T. Sadibekova +25
Cosmological probes based on galaxy clusters rely on cluster number counts and large-scale structure information. X-ray cluster surveys are well suited for this purpose, since they…
Understanding X-ray and optical selection of galaxy clusters: A comparison of the XXL and CAMIRA cluster catalogues obtained in the common XXL-HSC SSP area
J. P. Willis, M. Oguri, M. E. Ramos-Ceja +31
Large samples of galaxy clusters provide knowledge of both astrophysics in the most massive virialised environments and the properties of the cosmological model that defines our Un…
