Kamieneski Arizona State University N ------------------------------------------------------------------------------------ Abstract The conversion of gas into stars on small spatial scales, and its connection to the underlying stellar backbone is key to understanding quenching in cluster galaxies. However, the dearth of high-resolution maps of the molecular gas, star formation, and stars has made it impossible to understand these processes. Recently, a new window into spatially-resolved molecular gas and far-IR emission has been opened through ALMA observations of high-redshift clusters. These gains have been mainly due to the high source density of star forming galaxies in young clusters, which allows for large multiplexing. The ALMA observations have delivered spatial and kinematic maps of the molecular gas at exquisite resolution for the first large sample of high-redshift galaxies, while the available rest-frame UV HST and ALMA FIR data have yielded star formation maps. We will combine these novel ALMA and HST data with new imaging in F105W, F140W, and F160W to derive stellar mass maps and to investigate the spatial distribution of the dominant baryonic components in main-sequence cluster galaxies at z~1.6. The target cluster contains galaxies in remarkable states of transformation and will be combined with analogous available data on 2 other z~1.6 clusters for a total sample of 29 galaxies at the same redshift with high-resolution spatial maps of their star formation, stellar mass, and gas. With these data we will, for the first time: 1) measure where star formation in cluster galaxies is halted (outskirts, centers, or everywhere); 2) connect deviations from scaling relationships to the stellar backbone of the galaxy; and 3) learn what role clumps play in driving mass buildup in cluster galaxies. ------------------------------------------------------------------------------------ 17439( 5) - 25-Jun-2024 17:33:03 - [ 2] Observations Description ------------------------ The goal of this program is to obtain WFC3 imaging over a galaxy cluster at z=1.6 in three filters: F105W (4.5 orbits), F140W (1.5 orbits), and F160W (1 orbit). The observations are designed to cover in-hand ALMA, WFC3, and ACS imaging; the pointing coordinates have been chosen to maximize overlap with these images, in particular the existing (shallower) F160W imaging. Most of the primary targets of interest are within the central 80x80" diameter, with K band fluxes around 21-23 mags, and effective radii averaging around 0.7". We do not place orient constraints to maximize schedulability. Orbit / visit strategy: ----------------- Each visit consists of 1-2 orbits, over various filters. Visit 1 = 1 orbit in F140W and 1 orbit in F105W Visit 2 = 1/2 orbit in F140W and 1/2 orbit in F105W Visit 3 = 1 orbit in F160W and 1 orbit in F105W Visit 4 = 2 orbits in F105W In visits which contain F105W with another filter, we have placed the F105W exposures toward the middle of the orbit to help reduce the sky background from the airglow line of He I, which can affect some orbits. In these visits, the 4-point dither pattern (described below) for each filter is thus split over 2 orbits, which also reduces pointing maneuvers. Dithering strategy: --------------- We use a dither pattern with a combination of 1/2 pixel shifts to improve sampling of the PSF, and integer pixel shifts to enable rejection of hot/bad pixels and mitigate persistence from bright compact sources. We use a larger version of the standard WFC3-IR-DITHER-BOX-MIN pattern, which has only 1-4 pixel offsets between pointings. As some bad pixels come in clumps we prefer a slightly larger pattern. We use POS-TARG offsets to execute our dither pattern. The general 4-point dither pattern we use is: POS-TARG: (0, 0) (1.36, 0.428) (0.884, 1.216) (-0.476, 0.788) pixels: (0, 0) (10.0, 3.5) (6.5, 10.0) (-3.5, 6.5) To further mitigate for blobs, which can be 10-15 pixels in size, we apply shifts of +/-1.5 arcseconds in x and y to the starting position of the dither pattern for F105W and F140W filters, which have multiple orbits over several visits. This is again done through POS-TARG offsets, with the subsequent dither positions following the same overall pattern as above, calibrated to the new starting point. No attempt is made to dither over the "Death Star", as large dithers introduce large differential distortion. ------------------------------------------------------------------------------------ 17439( 5) -
