Morgan The Ohio State University Research N Foundation CoI: Dr. Xinyu Dai The Ohio State University Research N Foundation CoI: Dr. Eric Agol University of Washington N ------------------------------------------------------------------------------------ Abstract We can now routinely measure the size of quasar accretion disks using gravitational microlensing of lensed quasars. The next step to testing accretion disk models is to measure the size of accretion disks as a function of wavelength, particularly at the UV and X-ray wavelengths that should probe the inner, strong gravity regime. Here we focus on two four-image quasar lenses that already have optical (R band) and X-ray size measurements using microlensing. We will combine the HST observations with ground-based monitoring to measure the disk size as a function of wavelength from the near-IR to the UV. We require HST to measure the image flux ratios in the ultraviolet continuum near the Lyman limit of the quasars. The selected targets have estimated black hole masses that differ by an order of magnitude, and we should find wavelength scalings for the two systems that are very different because the Blue/UV wavelengths should correspond to parts of the disk near the inner edge for the high mass system but not in the low mass system. The results will be modeled using a combination of simple thin disk models and complete relativistic disk models. While requiring only 18 orbits, success for one system requires observations in both Cycles 16 and 17. ------------------------------------------------------------------------------------ 11225( 2) - 04/09/07 08:12 - [ 2] Observations Description ------------------------ We will be monitoring two gravitational lenses with the SBC/F165LP. The epochs should be spaced to span the visibility periods with roughly equal time periods between the observations. The visibility periods are May-September for Q2237 and December-March for RXJ1131. There are a further 6 epochs approved for Q2237 in Cycle 17, but not scheduled here. The observations themselves are simple single orbit, 4 position dithered SBC/F165LP observations. We have one such image of RXJ1131 already, and the results are as expected.
