Strong-lensing measurement of the total-mass-density profile out to three effective radii for z ∼ 0.5 early-type galaxies.

Abstract (from CDS):

We measure the total-mass-density profiles out to three effective radii for a sample of 63z ∼ 0.5, massive early-type galaxies (ETGs) acting as strong gravitational lenses through a joint analysis of lensing and stellar dynamics. The compilation is selected from three galaxy-scale strong-lens samples, namely the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey (BELLS), the BELLS for GALaxy-Lyα EmitteR sYstems Survey (BELLS GALLERY), and the Strong Lensing Legacy Survey (SL2S). Utilizing the wide source-redshift coverage (0.8-3.5) provided by these three samples, we build a statistically significant ensemble of massive ETGs for which robust mass measurements can be achieved within a broad range of Einstein radii up to three effective radii. Characterizing the three-dimensional total-mass-density distribution by a power-law profile as ρ ∝ r–γ, we find that the average logarithmic density slope for the entire sample is <γ>=2.000–0.032+0.033 (68 per cent CL) with an intrinsic scatter of δ=0.180–0.028+0.032. Further parametrizing <γ> as a function of redshift z and the ratio of Einstein radius to effective radius Rein/Reff, we find that the average density distributions of these massive ETGs become steeper at later cosmic times and at larger radii, with magnitudes d <γ>/ dz=-0.309–0.160+0.166 and d <γ>/ d log10 (R_ ein/R eff)=0.194-0.083_+0.092.
