BzK galaxy

BzK galaxies, or "BzK" which stands for "BnzK galaxies," refer to a specific class of galaxies identified in the study of galaxy formation and evolution, particularly in the context of cosmology and astrophysics. The term is often associated with a selection criterion used to identify a population of galaxies at high redshift (z > 1.4) which are likely to be massive and star-forming.
