The Optical, Ultraviolet, and X-ray Structure of the Quasar HE 0435-1223
Jeffrey A. Blackburne, Christopher S. Kochanek, Bin Chen +2
Microlensing has proven an effective probe of the structure of the innermost regions of quasars, and an important test of accretion disk models. We present light curves of the lens…
Discovery of Energy Dependent X-ray Microlensing in Q2237+0305
Bin Chen, Xinyu Dai, Christopher S. Kochanek +3
We present our long term Chandra X-ray monitoring data for the gravitationally lensed quasar Q2237+0305 with 20 epochs spanning 10 years. We easily detect microlensing variability…
The Gravitational Lens Equation for Embedded Lenses; Magnification and Ellipticity
Bin Chen, Ronald Kantowski, Xinyu Dai
We give the lens equation for light deflections caused by point mass condensations in an otherwise spatially homogeneous and flat universe. We assume the signal from a distant sour…
