Mass models and environment of the new quadruply lensed quasar SDSS J1330+1810
Masamune Oguri, Naohisa Inada, Jeffrey A. Blackburne +5
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 Sl…
HE 1113-0641: The Smallest Separation Gravitational Lens Identified by a Ground-based Optical Telescope
Jeffrey A. Blackburne, Lutz Wisotzki, Paul L. Schechter
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…
X-Ray and Optical Flux Ratio Anomalies in Quadruply Lensed Quasars: I. Zooming in on Quasar Emission Regions
David Pooley, Jeffrey A. Blackburne, Saul Rappaport +1
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…
A Strong X-Ray Flux Ratio Anomaly in the Quadruply Lensed Quasar PG 1115+080
David Pooley, Jeffrey A. Blackburne, Saul Rappaport +2
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…
X-Ray and Optical Flux Anomalies in the Quadruply Lensed QSO 1RXS J1131-1231
Jeffrey A. Blackburne, Dave Pooley, Saul Rappaport
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…
The Luminosity, Stellar Mass, and Number Density Evolution of Field Galaxies of Known Morphology from z = 0.5 - 3
Christopher J. Conselice, Jeffrey A. Blackburne, Casey Papovich
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-f…
