• W2102998321 abstract "We present the weak lensing and optical analysis of the SL2S-ARCS (SARCS) sample of strong lens candidates. The sample is based on the Strong Lensing Legacy Survey (SL2S), a systematic search of strong lensing systems in the photometric CanadaFrance-Hawaii Telescope Legacy Survey (CFHTLS). The SARCS sample focuses on arc-like features and is designed to contain mostly galaxy groups. We briefly present the weak lensing met hodology that we use to estimate the mass of the SARCS objects. Among 126 candidates, we obtain a weak lensing detection (at the 1σ level) for 89 objects with velocity dispersions of the Singu lar Isothermal Sphere mass model (SIS) ranging fromσS IS ∼ 350 km s −1 to∼ 1000 km s −1 with an average value ofσS IS ∼ 600 km s −1 , corresponding to a rich galaxy group (or poor cluster). From the galaxies belonging to the bright end of the group’s red se quence (Mi < −21), we derive the optical properties of the SARCS candidates. We obtain typical richnesses of N ∼ 5− 15 galaxies and optical luminosities of L∼ 0.5− 1.5× 10 12 L⊙ (within a radius of 0.5 Mpc). We use these galaxies to compute luminosity density maps, from which a morphological classification reveals tha t a large fraction of the sample (∼ 45%) are groups with a complex light distribution, either elliptical or multimodal, suggestin g that these objects are dynamically young structures. We fin ally combine the lensing and optical analyses to draw a sample of 80 most secure group candidates, i.e. weak lensing detection and over-density at the lens position in the luminosity map, to remove false detections and galaxy-scale systems from the initial sample. We use this reduced sample to probe the optical scaling relations in combination with a sample of massive galaxy clusters. We detect the expected correlations over the probed range in mass with a typical sca tter of∼ 25% inσS IS at a given richness or luminosity, making these scaling laws interesting mass proxies." @default.
