Constraining Quasar Relativistic Reflection Regions and Spins with Microlensing
Xinyu Dai, Shaun Steele, Eduardo Guerras +2
We present an analysis of Chandra spectra of five gravitationally lensed active galactic nuclei. We confirm the previous detections of FeK emission lines in most images of these…
Extended X-ray Monitoring of Gravitational Lenses with Chandra and Joint Constraints on X-ray Emission Regions
Eduardo Guerras, Xinyu Dai, Shaun Steele +5
We present an X-ray photometric analysis of six gravitationally lensed quasars, with observation campaigns spanning from 5 to 14 years, measuring the total (0.83 - 21.8 keV restfra…
Probing the gravitational Faraday rotation using quasar X-ray microlensing
Bin Chen
The effect of gravitational Faraday rotation was predicted in the 1950s, but there is currently no practical method for measuring this effect. Measuring this effect is important be…
Algorithms And Programs For Strong Gravitational Lensing In Kerr Space-time Including Polarization
Bin Chen, Ronald Kantowski, Xinyu Dai +2
Active galactic nuclei (AGNs) and quasars are important astrophysical objects to understand. Recently, microlensing observations have constrained the size of the quasar X-ray emiss…
Effects of Kerr Strong Gravity on Quasar X-ray Microlensing
Bin Chen, Xinyu Dai, Eddie Baron +1
Recent quasar microlensing observations have constrained the sizes of X-ray emission regions to be within about 10 gravitational radii of the central supermassive black hole. There…
Inclination-Dependent AGN Flux Profiles From Strong Lensing of the Kerr Space-Time
Bin Chen, Xinyu Dai, Eddie Baron
Recent quasar microlensing observations have constrained the X-ray emission sizes of quasars to be about 10 gravitational radii, one order of magnitude smaller than the optical emi…
X-ray Monitoring of Gravitational Lenses With Chandra
Bin Chen, Xinyu Dai, Christopher S. Kochanek +3
We present \emph{Chandra} monitoring data for six gravitationally lensed quasars: QJ 01584325, HE 04351223, HE 11041805, SDSS 0924+0219, SDSS 1004+4112, and Q 2237+0305. W…
