摘要: We report the discovery of a compact group of galaxies, CGG-z5, at z~5.2 in
the EGS field covered by the JWST/CEERS survey. CGG-z5 was selected as the
highest overdensity of galaxies at z>2 in recent JWST public surveys and it
consists of six candidate members lying within a projected area of
$1.5''\times3''$ (10$\times$20~kpc$^2$). All group members are HST/F435W and
HST/F606W dropouts while securely detected in the JWST/NIRCam bands, yielding a
narrow range of robust photometric redshifts $5.011$) at z~1. This implies that CGG-z5
could be a "proto-massive galaxy" captured during a short-lived phase of
massive galaxy formation.
