  • Low X-ray Luminosity Galaxy Clusters. III: Weak Lensing Mass Reconstruction at 0.18 < z < 0.70.


    This is the 3th of a series of papers on low X-ray luminosity galaxy clusters in which we present Weak Lensing Mass reconstructions based on the photometric images ... We develop a weak gravitational lensing analysis pipeline based on several public domain packages .. The Weak Lensing analysis pipeline is tested on a simulated images of a galaxy cluster field developed for the DES survey, providing a recovery of the (induced or injected) mass distribution with high ... The high quality images allow us to reconstruct the projected mass density profiles showing ... Our results indicate ...

    dark matter – clusters: galaxies – X-rays.


    Weak and strong gravitational lensing are excellent tools to probe the projected mass distribution of clusters, with strong lensing confined to the central regions of clusters, whereas weak lensing can yield mass measurements for larger radii. Low luminosity X-ray clusters of galaxies have not been extensively studied compared to more massive systems, nevertheless .. Here we present a weak lensing analysis pipeline based on well stablished techniques such as: ... Gravitational lensing analysis of low X-ray luminosity clusters of galaxies were done by Low X-ray galaxy clusters could shed light on the assembly processes and environmental effects on their galaxy population as those analyzed on paper I In this work we adopt when necessary a standard cosmological model: \(H_{0}\)=70h\(_{70}\)kms\(^{-1}\)Mpc\( ^{-1}\),
    \( \Omega_{m} \)=0.3, and \( \Omega_{\Lambda} \)=0.7. The plan of this paper is as follows. In Sec. \ref{sec:data}, we introduce the details of the systems of galaxies observed ... In Sec. \ref{sec:method}, we describe the WL pipeline methodology used ... and the methodology to estimate the corresponding errors. In Sec. \ref{sec:results} we present and discuss the results . Finally, in Sec. \ref{sec:conclusions} we summarise the main results of this work.
