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

Rui Li, Yiping Shu, Jiangcheng Wang

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 th…
