We present the discovery of a new quadruply lensed quasar. The lens system, SDSS J1330+1810 at z_s=1.393, was identified as a lens candidate from the spectroscopic sample of the Sloan Digital Sky...

The Hamburg/ESO quasar HE 1113-0641 is found to be a quadruple gravitational lens, based on observations with the twin 6.5m Magellan telescopes at the Las Campanas Observatory, and subsequently with...
Pooley, David, Blackburne, Jeffrey A., Rappaport, Saul, Schechter, Paul L.
X-ray and optical observations of quadruply lensed quasars can provide a microarcsecond probe of the lensed quasar, corresponding to scale sizes of \~10^2-10^4 gravitational radii of the central...
A Strong X-Ray Flux Ratio Anomaly in the Quadruply Lensed Quasar PG 1115+080 (2006)
Pooley, David, Blackburne, Jeffrey A., Rappaport, Saul, Schechter, Paul L., Fong, Wen-fai
PG 1115+080 is a quadruply lensed quasar at z=1.72 whose image positions are well fit by simple models of the lens galaxy (at z=0.31). At optical wavelengths, the bright close pair of images exhibits...
X-Ray and Optical Flux Anomalies in the Quadruply Lensed QSO 1RXS J1131-1231 (2005)
Blackburne, Jeffrey A., Pooley, Dave, Rappaport, Saul
Optical and X-ray observations of the quadruply imaged quasar 1RXS J1131-1231 show flux ratio anomalies among the images factors of ~2 in the optical and \~3-9 in X-rays. Temporal variability of the...

The evolution of rest-frame B-band luminosities, stellar masses, and number densities of field galaxies in the Hubble Deep Field North and South are studied as a function of rest-frame B-band...
