in GOODS-S field. NIRCam imaging ans slitless spectroscopy. confirmed 96 members through search of Halpha

“here protocluster members appeared more massive and exhibited earlier star formation (and thus older stellar populations) when compared to their field galaxy counterparts.”

“13.0 . log10 (Mhalo/M ) . 13.5 using an empirical stellar mass to halo mass relation, although this is likely an underestimate as a result of incompleteness.”
