COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses VII. Time delays and the Hubble constant from WFI J2033-4723
C. Vuissoz, F. Courbin, D. Sluse +10
Gravitationally lensed quasars can be used to map the mass distribution in lensing galaxies and to estimate the Hubble constant H0 by measuring the time delays between the quasar i…
X-Ray and Optical Microlensing in the Lensed Quasar PG 1115+080
Christopher W. Morgan, Christopher S. Kochanek, Xinyu Dai +2
We analyzed the microlensing of the X-ray and optical emission of the lensed quasar PG 1115+080. We find that the effective radius of the X-ray emission is 1.3(+1.1 -0.5) dex small…
Simultaneous Estimation of Time Delays and Quasar Structure
Christopher W. Morgan, Michael E. Eyler, C. S. Kochanek +5
We expand our Bayesian Monte Carlo method for analyzing the light curves of gravitationally lensed quasars to simultaneously estimate time delays and quasar structure including the…
Turning AGN Microlensing From a Curiosity Into a Tool
C. S. Kochanek, X. Dai, C. Morgan +3
Microlensing of gravitationally lensed quasars by the stars in the foreground lens galaxy can be used to probe the nature of dark matter, to determine the mean stellar mass in the…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112
J. Fohlmeister, C. S. Kochanek, E. E. Falco +12
We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
Microlensing of the Lensed Quasar SDSS0924+0219
Christopher W. Morgan, C. S. Kochanek, Nicholas D. Morgan +1
We analyze V, I and H band HST images and two seasons of R-band monitoring data for the gravitationally lensed quasar SDSS0924+0219. We clearly see that image D is a point-source i…
