Riley Owens University of Cincinnati Main Campus N ------------------------------------------------------------------------------------ Abstract Our understanding of the EOR will be limited by our ability to directly study the physical mechanisms that regulate LyC escape in galaxies where LyC escape can be directly measured. However, revealing the physics of LyC requires resolving the relevant physical scales, which are increasingly believed to be small, i.e. on the order of the size of individual compact star clusters (~10-100 pc). This work can only be performed with detailed studies of bright, highly magnified LyC leaking systems, but currently there is only one such system known (the Sunburst Arc). We propose UV/blue HST imaging of LyC and LyA of SGAS1110, an exceptionally magnified strongly lensed galaxy at z=2.48. The proposed data will spatially resolve escaping LyC and LyA radiation down to ~30 pc scales, identifying channels of extremely low HI column density. The target galaxy has a double-peaked LyA emission profile observed from galaxy-integrated ground-based spectroscopy, as well as JWST/NIRSpec IFU spectroscopy that identifies multiple compact star forming regions with extreme ionization (O3/O2 >11 and Ne3/O2 > 1.5; implying log(U) of ~ -1). These regions have nearly identical properties to the extreme LyC leaking region in the Sunburst Arc, which is associated with a single compact star cluster, ~<10 pc in size. This program would provide the crucial missing piece (direct imaging of spatially resolved LyC and LyA escape) to use SGAS1110 as a new laboratory for understanding the relationship between ionizing photon escape and spatially resolved physical properties on the physical scales of individual star clusters, as well as role that complex galaxy and ISM geometries play in enabling LyC escape. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program will measure rest-frame Lyman Continuum (LyC; lambda < 912A) and Lyman-Alpha (lyA; rest-frame lamba = 1216A) emission from a bright, strongly lensed galaxy at z=2.481. The WFC3/UVIS F275W filter captures the LyC emission and the ACS/WFC FR423N tunable narrowband ramp filter captures the LyA 17728( 4) - 15-Aug-2024 14:49:11 - [ 2] emission. We note that in the event that ACS/WFC becomes decommissioned, the FR423N observations can also be performed using the FQ423M (a very narrow medium band) filter on WFC3/UVIS. Observations in both filters are deep -- 29 orbits in F275W and 15 orbits in FR423N -- and so idividual exposures will span an entire orbit, with orbits grouped into separate visits that each consist of 3, 4 or 5 orbits to facilitate shedulability. We will reconstruct the undersampled PSF by dithering exposures using 3-pt line, 4-pt box, or 5-pt line sub-pixel dither patterns within each visit, where the number of positions match the number of orbits in a given visit. We also adjust the main target coordinates slightly (by a few arcseconds) between visits to provide larger offsets to fill in chip defects and to fill in the WFC3/UVIS chip gap. Our aperture selections are chosen to optimize the signal-to-noise of our primary target, which is quite small -- the three bright images of the lensed galaxy all fall within a ~7x20 arcsecond region of the sky. The primary target is the central (most magnified) image of the galaxy which covers a region on the sky ~3x9arceseconds. For the F275W observations we use the UVIS2-C1K1C-CTE aperture, which places the target in the corner of chip 2 near the readout, thus minimizing CTE losses. The target is small enough (maximum extent ~7x20arcsec) that it will easily fall onto the detector (>~ 15 arcsec from the edge) regardless of the position angle of the observation. For the FR423N observations we use the WFC1-IRAMP aperture, which is matched to the FR423N ramp filter being located on the inner part of the ramp filter wheel. The FOV of the monochromatic inner ramp filter region (~25x75 arcseconds). These observations will comfortably fit three bright images of the lensed galaxy (as well as the higheest priority central image that is most highly manified) within the ACS/WFC ramp filter field of view at any position angle. ------------------------------------------------------------------------------------ 17728( 4) -
