Abstract:
Constraints on the mass distribution in high-redshift clusters of
galaxies are currently not very strong.
We aim to constrain the mass profile, M(r), and dynamical status of
the z∼0.8 LCDCS 0504 cluster of galaxies that is characterized by
prominent giant gravitational arcs near its center.
Our analysis is based on deep X-ray, optical, and infrared imaging as
well as optical spectroscopy, collected with various instruments,
which we complemented with archival data. We modeled the mass
distribution of the cluster with three different mass density
profiles, whose parameters were constrained by the strong lensing
features of the inner cluster region, by the X-ray emission from the
intracluster medium, and by the kinematics of 71 cluster members.
Description:
We refer to Guennou et al. (2010A&A...523A..21G 2010A&A...523A..21G) for a complete
description of the optical and infrared imaging data and for the
evaluation of photometric redshifts, zp.
We collected 116 galaxy redshifts from the NED database, originally
from Halliday et al. (2004A&A...427..397H 2004A&A...427..397H, Cat. J/A+A/427/397),
obtained with VLT/FORS2 observations in a 5-arcmin radius around the
cluster center.
We downloaded the publicly available XMM-Newton observations of LCDC
0504: ID 0143210801, observed in 07/2003, PI D. Zaritsky, and ID
0651770201, observed in 12/2010, PI B. Maughan.
