JWST color-composed image of the Cosmic Vine (Red: F356W+F410W+F444W; Green: F200W+F277W; Blue: F115W+F150W). Left: The large scale structure. Sources with 3.435 < z_spec < 3.455 are marked with green circles. The white contours show the overdensity of 3.2 < z_phot < 3.7 sources in step levels of 2, 4, and 6σ. Right: 10″ × 10″ images centered on two massive galaxies in the Cosmic Vine. Galaxies with z_spec are highlighted with green arrows, and candidate members with 3.3 < z_phot < 3.6 are marked with cyan arrows.
