XMM-Newton Survey of Gaia-Selected Strongly Lensed Quasars

Combining the exquisite angular resolution of Gaia (< 0.2 arcsec) with opticallight curves and WISE photometry, the Gaia Gravitational Lenses working group(GraL) have confirmed 22 new strongly lensed quasars in the past two years,including 9 new quadruply lensed quasars. Xray observations of these raresystems provide a powerful tool for a range of studies, from inferring thestructure near the event horizons of supermassive black holes (SMBHs) tomeasuring black hole spins at cosmological distances. We propose a snapshotsurvey of these newly identified systems to determine which are the most Xraybright and therefore amenable to future deeper observations and monitoringprograms. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
