Gravitational Lensing Size Scales for Quasars
G. Chartas, C. Rhea, C. Kochanek +6
We review results from our monitoring observations of several lensed quasars performed in the optical, UV, and X-ray bands. Modeling of the multi-wavelength light curves provides c…
The SDSS-III BOSS quasar lens survey: discovery of thirteen gravitationally lensed quasars
Anupreeta More, Masamune Oguri, Issha Kayo +15
We report the discovery of 13 confirmed two-image quasar lenses from a systematic search for gravitationally lensed quasars in the SDSS-III Baryon Oscillation Spectroscopic Survey…
Structure of the Accretion Disk in the Lensed Quasar Q2237+0305 from Multi-Epoch and Multi-Wavelength Narrow Band Photometry
J. A. Munoz, H. Vives-Arias, A. M. Mosquera +3
We present estimates for the size and the logarithmic slope of the disk temperature profile of the lensed quasar Q2237+0305, independent of the component velocities. These estimate…
A Consistent Picture Emerges: A Compact X-ray Continuum Emission Region in the Gravitationally Lensed Quasar SDSS J0924+0219
Chelsea L. MacLeod, Christopher Morgan, A. Mosquera +7
We analyze the optical, UV, and X-ray microlensing variability of the lensed quasar SDSS J0924+0219 using six epochs of Chandra data in two energy bands (spanning 0.4-8.0 keV, or 1…
