My understanding is the F140W IR and G141 GRISM1024 apertures are equivalent. Infrared Grism Confirmation of a Strongly Lensed z ~ 11 Candidate: MACS0647-JD The first galaxies are the frontier of extragalactic astronomy. How and when did they form, and how did they contribute to reionization? Gravitational lensing has enabled efficient discovery of high-redshift galaxies including MACS0647-JD at z ~ 10.8 (420 Myr after the Big Bang), a strong candidate for the most distant galaxy yet known. This discovery by the CLASH Multi-Cycle Treasury program is consistent with expectations extrapolated from lower redshifts (4 < z < 8). The evolving luminosity function fit to these data includes sufficient numbers of faint galaxies at early times to reionize the universe. However, the discovery of MACS0647-JD is in tension with lower number densities of z > 9 candidates identified in deep field observations including the UDF. These field studies suggest z > 9 galaxies were building up in numbers much more rapidly than observed at later times. Confirmation of the z ~ 10.8 candidate is therefore paramount to our understanding of early galaxy evolution and reionization. All three strongly lensed images of MACS0647-JD are significantly detected in two HST filters (F140W and F160W). Lower redshift objects have been ruled out with high confidence, and the redshift is corroborated by our lens modeling. The strong lensing magnification provides us with a rare opportunity to confirm such a high redshift. We propose to do so with ten orbits of WFC3/IR G141 grism observations. Two orbits of F140W imaging are also required for calibration. As the first ever HST IR grism observations of a z < 1 cluster, this program will serve as an important pathfinder for future IR grism observations of lensed fields with HST and with the James Webb Space Telescope. We will observe MACS0647+7015 for a total of 12 HST orbits (10 orbits G141 grism + 2 orbits F140W imaging) at 3 roll angles (U3 = 53, 165, 204 degrees) carefully selected to minimize contamination of the high-redshift candidate spectra. At each of the 3 roll angles, we will observe for 4 orbits. Each of these 4 orbits will be obtained at a different dither position, following the optimal dither pattern described in Brammer12a. Each orbit will begin with a ~5-minute F140W "direct image" prior to the G141 observations. All G141 observations will be NSAMP=15 SPARS100. All F140W observations will be SPARS50. Thus at each roll angle, we'll have time for the following sequences with exposure times given in seconds (and NSAMP x SPARS in parentheses): Orbit 1) (initial guide star acquisition) F140W 353 ( 8 x 50) G141 1403 (15 x 100) G141 1403 (15 x 100) Orbits 2-4) (guide star re-acquisitions) F140W 503 (11 x 50) G141 1403 (15 x 100) G141 1403 (15 x 100) COSMOLOGY Default false false false false false SUPPORTED CLUSTER OF GALAXIES GRAVITATIONAL LENS HIGH REDSHIFT CLUSTER J2000 J2000 WFC3/IR Spectroscopic No No G141 WFC3/IR Imaging No No F140W The scheduling data was generated by CASM 22.2.
