HD1

HD1 is a galaxy-candidate identified in 2022, apparently with a higher redshift of than any known galaxy, i.e., z = 13.27. Both HD1 and another such candidate, HD2, were so-termed to indicate they were identified for being H band dropouts, that indicate a Lyman-break galaxy (LBG) at that redshift. Spectrography consistent with the redshift would confirm either as a discovery. HD1 was discovered in Cosmic Evolution Survey data.
