X-ray and Optical Flux Ratio Anomalies in Quadruply Lensed Quasars: I. Zooming in on Quasar Emission Regions
X-ray and optical observations of quadruply lensed quasars can provide a micro-arcsecond probe of the lensed quasar. In this paper we utilize X-ray observations of ten lensed quasars recorded with the Chandra X-ray Observatory as well as corresponding optical data obtained by either the Hubble Space Telescope or ground-based optical telescopes. These are analyzed in a systematic and uniform way...
متن کاملX-ray and Optical Flux Ratio Anomalies in Quadruply Lensed Quasars: I. Zooming in on Quasar Emission Regions1
X-ray and optical observations of quadruply lensed quasars can provide a microarcsecond probe of the lensed quasar, corresponding to scale sizes of ∼ 102 − 104 gravitational radii of the central black hole. This high angular resolution is achieved by taking advantage of microlensing by stars in the lensing galaxy. In this paper we utilize X-ray observations of ten lensed quasars recorded with t...
متن کاملFlux and color variations of the quadruply imaged quasar
Aims. We present VRi photometric observations of the quadruply imaged quasar HE0435-1223, carried out with the Danish 1.54 m telescope at the La Silla Observatory. Our aim was to monitor and study the magnitudes and colors of each lensed component as a function of time. Methods. We monitored the object during two seasons (2008 and 2009) in the VRi spectral bands, and reduced the data with two i...
متن کاملObservations of the Quadruply Lensed Quasar RX J 0911 . 4 + 0551
We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra X-ray Observatory. The 29 ks observation detects a total of ∼ 404 X-ray photons (0.3 to 7.0 keV) from the four images of the lensed quasar. Deconvolution of the aspect corrected data resolves all four lensed images, ...

We present results from X-ray observations of the quadruply lensed quasar RX J0911.4]0551 using data obtained with the Advanced CCD Imaging Spectrometer on board the Chandra X-Ray Observatory. The 29 ks observation detects a total of D404 X-ray photons (0.3 to 7.0 keV) from the four images of the lensed quasar. Deconvolution of the aspect-corrected data resolves all four lensed images, with rel...
