Optical‐to‐virial velocity ratios of local disc galaxies from combined kinematics and galaxy–galaxy lensing

ABSTRACT In this paper, we measure the optical‐to‐virial velocity ratios Vopt/V200c of disc galaxies in the Sloan Digital Sky Survey (SDSS) at a mean redshift of 〈z〉 = 0.07 and with stellar masses 109 < M* < 1011 M⊙. Vopt/V200c, the ratio of the circular velocity measured at the optical radius...
