TL;DR
This paper presents a comprehensive analysis of MUSE spectroscopic observations of 12 massive galaxy clusters, identifying thousands of redshifts and strongly lensed sources, enabling detailed studies of cluster and background galaxy properties.
Contribution
It provides a systematic methodology for data reduction, source detection, redshift determination, and mass modeling for multiple galaxy clusters observed with MUSE, including a large catalog of lensed sources.
Findings
Identified 312 strongly lensed sources with 939 multiple images.
Constructed robust mass models confirming redshift measurements.
Detected over 3300 redshifts, including many new line emitters not seen in HST images.
Abstract
Spectroscopic surveys of massive galaxy clusters reveal the properties of faint background galaxies, thanks to the magnification provided by strong gravitational lensing. We present a systematic analysis of integral-field-spectroscopy observations of 12 massive clusters, conducted with the Multi Unit Spectroscopic Explorer (MUSE). All data were taken under very good seeing conditions (0.6") in effective exposure times between two and 15 hrs per pointing, for a total of 125 hrs. Our observations cover a total solid angle of ~23 arcmin in the direction of clusters, many of which were previously studied by the MACS, Frontier Fields, GLASS and CLASH programs. The achieved emission line detection limit at 5 for a point source varies between (0.77--1.5)10 erg\,s\,cm at 7000\AA. We present our developed strategy to reduce these observational data,…
