Strong-lensing Measurement of the Mass-density Profile out to 3 Effective Radii for $z\sim 0.5$ Early-type Galaxies

Abstract

We measure the total mass-density profiles out to three effective radii for a sample of 63 $z\sim 0.5$, 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 including the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey (BELLS), BELLS for GALaxy-Ly$\alpha$ EmitteR sYstems Survey, and 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 $\rho \propto r^{-\gamma }$, we find that the average logarithmic density slope for the entire sample is $⟨\gamma ⟩=2.000_{-0.032}^{+0.033}$ ($68\%$CL) with an intrinsic scatter $\delta =0.180_{-0.028}^{+0.032}$. Further parameterizing $⟨\gamma ⟩$ as a function of redshift $z$ and ratio of Einstein radius to effective radius $R_{ein}/R_{eff}$, we find the average density distributions of these massive ETGs become steeper at larger radii and later cosmic times with magnitudes $\mathrm{d}⟨\gamma ⟩/\mathrm{d}z=-0.309_{-0.160}^{+0.166}$ and $\mathrm{d}⟨\gamma ⟩/\mathrm{d}{\log }_{10}\frac{R_{ein}}{R_{eff}}=0.194_{-0.083}^{+0.092}$.
