If there is a way to avoid this, I'm happy to resubmit a version combiing the epochs. In the previous versions of this program, we had trouble with guide stars for some of the UV targets -- here I have used pointing coordinates which yielded acceptable guide stars in the previous program. Updated after conversations with Alision Vick -- UV observations shifted to UVIS2 (more UV sensitive), visits 12/13, which were intended to be a single visit but had a buffer dump issue when set up that way, are tied to be within 1 week of each other Updated after conversations with Susana Deustua to flash the low background exposures to a background of ~12 and not use somewhat larger dithers than standard so that the cores of the quasar psfs would not be overlapping -1426639791 ----- Attempting Submission 1 (Mon Sep 10 18:26:46 GMT 2012) ----- HST Phase II Proposal 13113 (newuv.apt) successfully submitted. ----- Attempting Submission 2 (Tue Sep 11 13:10:29 GMT 2012) ----- HST Phase II Proposal 13113 (newuv.apt) successfully submitted. ----- Attempting Submission 3 (Fri Sep 14 19:40:01 GMT 2012) ----- ENERGY DEPENDENT X-RAY MICROLENSING AND THE STRUCTURE OF QUASARS The structure of the X-ray emitting regions of quasars remains an open question. Using microlensing in lensed quasars, we can now constrain the sizes, finding that they are compact compared to the UV emission (2500A) with 1/2 light radii of ~10-30 gravitational radii. We propose measuring the relative sizes of the hard and soft X-ray emission, better constraining the overall X-ray sizes and comparing them to the hottest regions of the accretion disk by coarsely monitoring 6 lenses with CXO (6 epochs each) and 5 with HST/UV (2 epochs). In essence, the variability amplitudes of the X-ray/UV compared to our well-sampled optical light curves allows us to measure the sizes. We request ~2/3 (1/3) of the time in Cycle 14 (15) for a total of 864~ks (with slew tax) and 12 HST orbits. The UV observations consists of pairs of observations separated by at least one year to look for gravitational microlensing variations in the image fluxes in order to estimate the size of the accretion disk in the (vacuum) UV. These are paired with monitoring observations in the X-ray with Chandra over the same two Cycle baseline. The 2 orbit optical observation of Q2237 is designed to calibrate our multicolor ground based light curves so that we can accurately estimate time variability in the image colors despite the presence of the bright lens galaxy. In essence we use the HST observations to calibrate ground based observations made at roughly the same epoch (weeks),and then can use difference imaging to provide a full calibration for our multi-year light curves. The only timing requirement is that the HST observations need to be done when the target is observable from the ground. This observation is driven by the need for high resolution to separate the quasar emission from the bulge of the galaxy as accurately as possible. The target is well up from our monitoring telescope at CTIO from June 22 to Oct 18 2013, so we should be guaranteed several weeks of light curve data before/after the HST observations. The quasar images are bright but buried in the bulge of the galaxy. We have set these up as a power law sequence of exposures (5, 10, 20, 40 sec) at each of 3 dither positions for each of the 4 filters -- this requires using the UVIS2-C1K1C-SUB aperture in order to minimize the read time overheads. This has a field of view comparable to our old WFPC2/PC images of the system, which is perfectly adequate to our goals. The shortest exposures are conservative, but since we will never be allowed to do this again, we need to be absolutely sure that we have redundant frames in all filters with no saturation. We expect no image to be brighter than 16th mag in any of the bands, and the 5 sec exposure at these bands will have SNR 120, 180, 130, 110 at F438W, F555W, F625W and F814W with a time to saturation of 95, 45, 86, and 140 sec if any image is this bright. The faintest we expect the images to be is 20 mag, where 40 sec exposures yield SNRs of 50, 80, 55, and 45, respectively. This strategy should guarantee unsaturated high SNR images in all bands no matter the state of the quasar in terms of variability.
