Substructures in galaxy clusters: a comparative X-ray and photometric analysis of the REXCESS sample
Gaël Foëx
The main goals of the present work are (i) to study the substructure content of a representative, X-ray selected sample of 31 galaxy clusters, as traced by the spatial distribution…
Compact Groups analysis using weak gravitational lensing
Martín Chalela, Elizabeth Johana Gonzalez, Diego Garcia Lambas +1
We present a weak lensing analysis of a sample of SDSS Compact Groups (CGs). Using the measured radial density contrast profile, we derive the average masses under the assumption o…
Weak lensing measurement of the mass-richness relation using the SDSS database
Elizabeth Johana Gonzalez, Facundo Rodriguez, Diego García Lambas +3
We study the mass-richness relation using galaxy catalogues and images from the Sloan Digital Sky Survey. We use two independent methods, in the first one, we calibrate the scaling…
The matter distribution in z ~ 0.5 redshift clusters of galaxies. II : The link between dark and visible matter
Genevieve Soucail, Gael Foex, Etienne Pointecouteau +2
We present an optical analysis of a sample of 11 clusters built from the EXCPRES sample of X-ray selected clusters at intermediate redshift (z ~ 0.5). With a careful selection of t…
Low X-ray Luminosity Galaxy Clusters. III: Weak Lensing Mass Determination at 0.18 z 0.70
Elizabeth Johana Gonzalez, Gael Foëx, José Luis Nilo Castellón +5
This is the third of a series of papers of low X-ray luminosity galaxy clusters. In this work we present the weak lensing analysis of eight clusters, based on observations obtained…
The abundance of Bullet-groups in LCDM
J. G. Fernandez-Trincado, J. E. Forero-Romero, G. Foex +2
We estimate the expected distribution of displacements between the two dominant dark matter (DM) peaks (DM-DM displacements) and between DM and gaseous baryon peak (DM-gas displace…
