Probing the influence of the protocluster environment on galaxy morphology at z = 2.23
Emmet Golden-Marx, Zheng Cai, Dongdong Shi +7
As galaxies evolve in dense cluster and protocluster environments, they interact and quench their star formation, which gradually transforms the galaxy population from star-forming…

The HST-Hyperion Survey: Environmental Imprints on the Stellar-Mass Function at z~2.5
Derek Sikorski, Ben Forrest, Brian C. Lemaux +19
Not all galaxies at Cosmic Noon evolve in the same way. It remains unclear how the local environment -- especially the extreme overdensities of protoclusters -- affects stellar mas…

The HST-Hyperion Survey: Grism Observations of a Proto-Supercluster
Ben Forrest, Lu Shen, Brian C. Lemaux +19
We present first results and catalogs from the HST-Hyperion survey. This survey has collected 50 orbits of WFC3/F160W imaging and WFC3/G141 grism spectroscopy in the most overdense…
