Example of spectroscopically confirmed members of Bigfoot. The upper panel presents the redshift distribution of 55 spectroscopically confirmed galaxies. As examples, the lower panels show the JWST spectroscopy of four confirmed member galaxies in 0217A, their best-fit SED from Bagpipes, and the 4″ × 4″ RGB cutouts from the JWST/NIRCam images.
