The Average Size and Temperature Profile of Quasar Accretion Disks
J. Jiménez-Vicente, E. Mediavilla, C. S. Kochanek +4
We use multi-wavelength microlensing measurements of a sample of 10 image pairs from 8 lensed quasars to study the structure of their accretion disks. By using spectroscopy or narr…
The Structure of the X-ray and Optical Emitting Regions of the Lensed Quasar Q 2237+0305
A. M. Mosquera, C. S. Kochanek, B. Chen +3
We use gravitational microlensing to determine the size of the X-ray and optical emission regions of the quadruple lens system Q 2237+0305. The optical half-light radius, log(R_{1/…
The Structure of the Broad Line Region in AGN: I. Reconstructed Velocity-Delay Maps
C. J. Grier, B. M. Peterson, Keith Horne +38
We present velocity-resolved reverberation results for five active galactic nuclei. We recovered velocity-delay maps using the maximum-entropy method for four objects: Mrk 335, Mrk…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses XIII: Time delays and 9-yr optical monitoring of the lensed quasar RX J1131-1231
M. Tewes, F. Courbin, G. Meylan +10
We present the results from nine years of optically monitoring the gravitationally lensed z=0.658 quasar RX J1131-1231. The R-band light curves of the four individual images of the…
Reverberation Mapping Results for Five Seyfert 1 Galaxies
C. J. Grier, B. M. Peterson, R. W. Pogge +40
We present the results from a detailed analysis of photometric and spectrophotometric data on five Seyfert 1 galaxies observed as a part of a recent reverberation mapping program.…
Further Evidence that Quasar X-Ray Emitting Regions Are Compact: X-Ray and Optical Microlensing in the Lensed Quasar Q J0158-4325
Christopher W. Morgan, Laura J. Hainline, Bin Chen +9
We present four new seasons of optical monitoring data and six epochs of X-ray photometry for the doubly-imaged lensed quasar Q J0158-4325. The high-amplitude, short-period microle…
Revealing the Structure of an Accretion Disk Through Energy Dependent X-ray Microlensing
G. Chartas, C. S. Kochanek, X. Dai +3
We present results from monitoring observations of the gravitationally lensed quasar RX J1131-1231 performed with the Chandra X-ray Observatory. The X-ray observations were planned…
A Reverberation Lag for the High-Ionization Component of the Broad Line Region in the Narrow-Line Seyfert 1 Mrk 335
C. J. Grier, B. M. Peterson, R. W. Pogge +37
We present the first results from a detailed analysis of photometric and spectrophotometric data on the narrow-line Seyfert 1 galaxy Mrk 335, collected over a 120-day span in the f…
A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
José A. Muñoz, Evencio Mediavilla, Christopher S. Kochanek +2
We report Hubble Space Telescope observations of 6 gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in 6 filters fro…
The Microlensing Properties of a Sample of 87 Lensed Quasars
Ana M. Mosquera, Christopher S. Kochanek
Gravitational microlensing is a powerful tool for probing the physical properties of quasar accretion disks and properties of the lens galaxy such as its dark matter fraction and m…
A Study of Gravitational Lens Chromaticity using Ground-based Narrow Band Photometry
Ana M. Mosquera, José A. Muñoz, Evencio Mediavilla +1
We present observations of wavelength-dependent flux ratios for four gravitational lens systems (SDSS~J1650+4251, HE~04351223, FBQ 0951+2635, and Q~0142100) obtained with the…
Microlensing-Based Estimate of the Mass Fraction in Compact Objects in Lens
E. Mediavilla, J. A. Munoz, E. Falco +6
We estimate the fraction of mass that is composed of compact objects in gravitational lens galaxies. This study is based on microlensing measurements (obtained from the literature)…
