The influence of gravitational lensing on the spectra of lensed QSOs
L. C. Popovic, G. Chartas
We consider the influence of (milli/micro)lensing on the spectra of lensed QSOs. We propose a method for the observational detection of microlensing in the spectra of lensed QSOs a…
A Chandra observation of the z=2.285 galaxy FSC10214+4724: Evidence for a Compton-thick quasar?
D. M. Alexander, G. Chartas, F. E. Bauer +3
We present a ~20 ks Chandra ACIS-S observation of the strongly lensed z=2.285 ultra-luminous infrared galaxy FSC10214+4724. Although this observation achieves the equivalent sensit…
Chandra Observations of Radio-Loud Quasars at z > 4: X-rays from the Radio Beacons of the Early Universe
L. C. Bassett, W. N. Brandt, D. P. Schneider +3
We present the results of Chandra observations of six radio-loud quasars (RLQs) and one optically bright radio-quiet quasar (RQQ) at z = 4.1-4.4. These observations cover a represe…
The Power of Exploratory Chandra Observations
S. C. Gallagher, G. T. Richards, W. N. Brandt +1
With its excellent spatial resolution, low background, and hard-band response, the Chandra X-ray Observatory is ideal for performing exploratory surveys. These efficient, sensitive…
A survey of extended radio jets with Chandra and HST
R. M. Sambruna, J. K. Gambill, L. Maraschi +5
We present the results from an X-ray and optical survey of a sample of 17 radio jets in AGN performed with Chandra and HST. The sample was selected from the radio and is unbiased t…
Chandra Observations of the Cloverleaf Quasar H 1413+117: A Unique Laboratory for Microlensing Studies of a Lobal Quasar
G. Chartas, M. Eracleous, E. Agol +1
We present new results uncovered by a re-analysis of a Chandra observation of the gravitationally lensed, low-ionization broad absorption line (LoBAL) quasar H 1413+117. Previous a…
