We compared the total mass density profiles of three different types ofgalaxies using weak gravitational lensing: (i) 29 galaxies that host quasars atz~0.32 that are in a post-starburst (PSQ) phase with high star formationindicating recent merger activity, (ii) 22 large elliptical galaxies from theSLACS sample that do not host a quasar at z~0.23, and (iii) 17 galaxies thathost moderately luminous quasars at z~0.36 powered by disk instabilities, butwith no intense star formation. On an initial test we found no evidence for aconnection between the merger state of a galaxy and the profile of the halo,with the PSQ profile comparable to that of the other two samples and consistentwith the Leauthaud et al. (2014) study of moderately luminous quasars inCOSMOS. Given the compatibility of the two quasar samples, we combined theseand found no evidence for any connection between black hole activity and thedark matter halo. All three mass profiles remained compatible withisothermality given the present data.
