After carefully decomposing spectra from the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) Quasar Catalog into quasar and host-galaxy components, we derive a sample of 208 PSQs. Their host-galaxy components have strong H{delta} absorption (EW&gt;=6{AA}) indicating a significant contribution of an intermediate-aged stellar population formed in a burst of star formation within the past 1Gyr, which makes them potentially useful for studying the co-evolution of supermassive black holes and their host galaxies.</description><source format="bibcode">2018ApJ...857...27W</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/857/27</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/VII/260">VII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/663/81">J/ApJ/663/81 : SED of hard X-ray selected AGN in XMDS (Polletta+, 2007)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/528/A35">J/A+A/528/A35 : Infrared luminosity in GOODS fields (Magnelli+, 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/194/45">J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/757/13">J/ApJ/757/13 : IR SEDs of 24um z~0.3-3 galaxies (Sajina+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/420/1684">J/MNRAS/420/1684 : End of red sequence galaxies in Galaxy Zoo (Wong+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/214/23">J/ApJS/214/23 : IR spectra and photometry of z&lt;0.5 quasars (Shi+, 2014)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/811/91">J/ApJ/811/91 : SDSS-RM project: z&lt;1 QSO host galaxies (Matsuoka+, 2015)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/819/L27">J/ApJ/819/L27 : Stellar masses of optical &amp;
