We are aware of this issue and took care in selecting dither patterns to avoid any problems. Large-separation (r>10") lensed quasars are extremely rare, but provide opportunities to zoom in maximally on quasar host galaxies. With magnification factors of ~20+, these systems enable studies that are impossible with quasars in the field, or even lower magnification galaxy-quasar lens systems. Lyman-alpha emission scatters resonant off of neutral hydrogen, and so its physical extent and distribution therefore provides a direct tracer of the neutral H gas content in galaxies. We propose to leverage the uniquely powerful combination of HST optical narrowband imaging (to isolate Lyman-alpha) and strong gravitational lensing to directly image the spatial distribution of neutral H on ~<100-200 pc physical scales within five quasar host galaxies at z=1.9-3.3. Archival HST+JWST broadband imaging constrains the spatially resolved stellar populations, providing maps of ionizing photon production from the stars so that we can robustly compare Lyman-alpha production against the Lyman-alpha narrowband imaging to quantity spatially resolved Lyman-alpha escape. The extreme magnifications allows for a clean separation of quasar vs host galaxy light to within ~100-200 parsecs of the central AGN engines. The resulting high resolution narrowband Lyman-alpha imaging data will unobtainable with any near term facility once HST ceases operations, and will hold substantial legacy value that will enhance future spatially resolved NIR spectroscopic studies of these quasar host galaxies. This is a program to use the tunable ramp filters on ACS/WFC to obtai narrowband imaging of redshifted Lyman alpha from a sample of wide-separation strongly lensed quasars (WSLQs) and their host galaxies. Broadband HST imaging to measure the Lyman-alpha-free continuum emission is available in the archive for all targets. Each target is a strong lensing system with multiple highly magnified images of background quasars, with those multiple images separated by as much as 26" on the sky. The ACS ramp filters provide uniform narrowband throughput over regions of the sky approximately 40"x60" in size, which means that all of the lensed images of each of the WSLQ targets will easily fit within the ramp filter field of view. The observational setup for this program is fairly simple - we're taking a few long integrations on each field in the appropriate narrowband filter. Four of the five targets will be observed with half-orbit integrations, and one target (The highest redshift one) will be observed with 8 full-orbit integrations. The 8 full-orbit integrations should be sufficient to remove cosmic rays even from the very long exposures. Members of this proposal team have extensive expertise working with massive galaxy clusters and using strong lensing to study the properties of highly magnified galaxies across the entire observable electromagnetic spectrum. Our collaboration has extensive experience with interpreting and modeling lensing clusters (e.g., Dahle et al. 2013, ApJ, 773, 146; Sharon et al. 2012, ApJ, 746, 161; Gladders et al. 2013, ApJ, 764, 177, Bayliss et al. 2011, ApJS, 193, 8).

He is the PI of two previously approved HST programs using the ACS ramp filters to spatially resolve LyA in lensed galaxies (GO-13639 and GO-17728), and will serve as the overall project lead. All CoIs below will also contribute to some or all of: data reduction, analysis, and paper-writing. He authored a 2017 paper analyzing spatially resolved HST imaging and Lyman alpha spectroscopy of a strongly lensed quasar host galaxy (one of the targets in this proposal). Prof. Sharon is an expert on strong lens modeling, with extensive experience from building lens models based on multi-band HST imaging. She has worked extensively on several of the previously known lens systems where quasars are lensed by galaxy clusters: The first large separation lensed quasar SDSSJ1004 (Sharon et al. 2005, ApJ, 629, L73), and the sextuply lensed SDSSJ2222 which was discovered by our collaboration (Dahle et al. 2013, ApJ, 773, 146; Sharon et al. 2017, ApJ, 835, 5). Dr. Sharon was PI of an HST program that obtained broadband imaging of one of the targets of this proposal (GO-13337). Dr. Dahle has led a successful photometric monitoring campaign to measure time delays for the cluster-lensed quasar SDSSJ2222+2745 (the first two time delays were published in Dahle et al. 2015, ApJ, 813, 67) and is currently leading a similar effort for our proposed HST target SDSSJ1326+4806, using the 2.56m Nordic Optical Telescope. He is the PI of a new HST and JWST program to obtain broadband imaging of the WSLQ's targets in this proposal. He is the PI of one HST+JWST program (HST-GO-17726 and JWST-GO-06675) that will obtain broadband imaging of the targets in this proposal.
