Physics

Scientific paper

We will use microlensing, where the stars in a lens galaxy magnify the accretion disk of a gravitationally lensed quasar, to measure the sizes of the X-ray emission regions of 7 gravitationally lensed quasars with well-sampled optical light curves and accretion disk size measurements. We will use these to determine the scaling of the non-thermal emission regions with black hole mass. For two ``active'' systems, RXJ1131-1231 and Q2237+0305, we will use longer observations in order to measure the X-ray energy dependence of the size. We have HST time to monitor the 6 with UV flux to probe thermal emission from near the inner edge of the disk. These observations can only be done with Chandra because future X-ray observatories will lack the necessary angular resolution.
