Post-Starburst Quasars (PSQs) are broad-lined AGNs that show clear Balmer jumps and high-order Balmer absorption lines in their spectra. They are hypothesized to represent a stage in the evolution of massive galaxies in which both, star formation and nuclear activity, have been triggered and are visible simultaneously before one or the other fades. This simultaneity may be explained by two possible scenarios: 1) the secular evolutionary scenario, in which star formation may cease due to exhaustion of the gas; and 2) the quenching scenario, where star formation may cease abruptly when the nuclear activity is triggered. Here I will show some results of the analysis of 3 PSQs by using Optical Integral Field Spectroscopy (IFS). These include the analysis of the stellar and gas kinematics by using IDL and Python codes.
