HST Phase I Proposal 7505 successfully submitted.
Receipt: # 7505-1
This is an updated version where the orientation angles have been updated to try to minimize spectral trace collisions especially in the cluster cores. The initial visits now have specified absolute orientation ranges which I believe are good for all the clusters but in two cases, SPT2040 and SPT0459 I had to further modify them in order to get these visits to schedule. I'm open to further adjustments to the roll angles if the PC and SC think it would preform better.

Star formation, nuclear activity and quenching in the most massive clusters at z~1.5
We propose 43 orbits of WFC3 G102 and G141 grism observations of five most distant (1.4<z<1.7) SZE-selected galaxy clusters from the 2500 sq.deg. SPT-SZ survey. This project leverages a unique, homogeneous, representative sample of the rarest, most massive clusters at z~1.5, to investigate critical aspects of galaxy evolution, providing at the same time a fundamental, well-defined observational counterpart to the most massive halos in cosmological simulations. The proposed cluster sample is ideally suited for such observations, both science wise (due to its clean selection, clear characterization, strongest environmental signatures due to very high cluster masses) and for observing efficiency (high cluster mass implies large sample of cluster galaxies).
The proposed grism spectra simultaneously probe spectral features sensitive to stellar age, star formation rate and optical AGN emission, crucially complementing an already extensive data set across the spectrum (X-ray through radio) from programs on all major facilities, to explore star formation, nuclear activity, quenching and structural evolution of galaxies in massive cluster cores. The proposed observations are necessary to obtain a large, representative, statistically meaningful, spectroscopically confirmed sample of cluster galaxies at z~1.5, and to constrain their fundamental properties. This program will provide a critical counterpart to analogous large population studies at z~1, at a crucial epoch probing the transition between z>2 protoclusters and established, already quenched clusters at z<1.
We propose to observe five of the highest-mass and highest-redshift galaxy clusters known from the SPT-SZ cluster survey. We will obtain HST/WFC3 observations in F105W/G102 and F160W/G141 filters and grisms. The proposed observations are designed to characterize stellar age, SFR, and nuclear activity down to m_F140W < 23.5.
We make 1 orbit per visit, allowing for flexibility in telescope orient angles. For the three lower-redshift clusters (SPT0421, SPT0607, and SPT2040) we offset the visits by angles to minimize spectral collisions as determined by visual inspection. For the F105W/G102 exposures we perform 2 matching visits per orient angle configuration. For the intermediate-redshift cluster, SPT0446, we add an additional fourth orientation angle to maximize unique orients in the added orbit. For the highest-redshift cluster, SPT0459, we have four orients, each with a matching visit.
For the F160W/G141 observations, we perform 2 visits per cluster offsetting the second visit by angles determined to minimize spectral collisions determined by visual inspection.
One cluster, SPT0421, has a bright source (an X-ray AGN) just south of the central cluster galaxy. We have provided broad orientation constrains to attempt to avoid spectral collision by this source onto the cluster galaxies.
All visits follow an ABBA sequence with "A" and "B" corresponding to imaging and grism exposures respectively. All exposure parameters within visits have been optimized to maximize the utilization of the available orbit visibilities.
Dr Canning, Dr Floyd, Dr Pannella and Dr Strazzullo co-lead these observations and will co-lead their reduction and analyses. They have significant collective expertise in all aspects of these imaging and grism data.
Dr. Canning has expertise in HST data reduction including HST WFC3 Grism data and has led successful proposals for this instrument before and several successful proposals with other HST observations. Dr. Canning is an expert in galaxy and AGN evolution in the cluster environment, both radiatively efficient and radiatively inefficient AGN.
Dr. Floyd is an expert on AGN selection functions across wavelength regimes and has significant experience working with statistical samples of multi-wavelength AGN in the cluster environment and their host galaxies and particular expertise in IR data. He also has extensive experience with rest-frame UV/optical spectroscopy.
Dr. Pannella is an expert in multi-wavelength studies of galaxy populations at intermediate to high redshift, including in particular the exploitation of multi-band photometry for the estimation of galaxy properties, with specific reference to star formation, dust attenuation and quenching across cosmic time and different environments.
Dr. Strazzullo is an expert in observational studies of cluster galaxies at high redshift, with direct expertise with HST observations for the study of galaxy morphology and stellar population properties. She has led two HST programs and several publications on high-redshift cluster galaxies based on HST observations. This proposal builds on results published in Strazzullo et al. (2019, 2023) on the five clusters targeted here, based on HST Cycle 23 and Spitzer Cycle 12 programs both led by Dr. Strazzullo.
Most of the co-investigators are members of the cluster working group of the South Pole Telescope (SPT) collaboration.
Dr. Allen, Dr. Bleem, Dr. Benson, Dr. Bocquet, Dr. McDonald, Dr. Mohr, Dr. Saro, Dr. Schrabback, Dr. Sharon and Dr. Stark are involved in the SPT survey definition and/or in the characterization of the SPT cluster sample up to high redshift.
Dr. Allen, Dr. von der Linden, and Dr. Mantz are experts in X-ray galaxy cluster cosmology and scaling relations, and in the characterization of the SPT-SZ cluster sample in terms of cluster masses, radii, X-ray morphology. Dr. Forman and Dr. McDonald are experts in X-ray observations of the hot ICM in clusters and the evolution of the hot gas.
Dr. Ashby, Dr. Bayliss, Dr. Bleem, Dr. Gladders, Dr. Khullar, Dr. Kim, Dr. Klein, Dr. Mahler, Dr. Schrabback, Dr. Sharon and Dr. Stalder are involved in the optical/NIR imaging and spectroscopy follow-up of SPT clusters up to high redshift, especially devoted to their confirmation and characterization.
Dr. Ashby is also especially involved in particular in the analysis of the Spitzer/IRAC follow-up of SPT clusters, and will provide crucial input on the optimal analysis of IRAC imaging that will be used as a complement to the proposed observations for the science project described in the proposal.
Dr. Canning, Dr. Floyd, Dr. Gladders, Dr. Gonzalez, Dr. Hlavacek-Larrondo, Dr. Mahler, Dr. McDonald, Dr. Mohr, Dr. Noble, Dr. Pannella, Dr. Saro, and Dr. Willis are all involved in different aspects of the study of the formation and evolution of cluster galaxies. Most of them are established experts in the field, and have led or participated in several landmark studies of galaxy populations in cluster environments up to high redshifts, also in particular with HST. Dr. Lustig works on morphological analyses of high-redshift galaxies with HST imaging.
Dr. De Lucia and Dr. Borgani are experts in theoretical models of galaxy formation in a cosmological context. Together with Dr. Marini, they contribute simulated data and expertise for the comparison of observations and theoretical models in this project.
