Galaxy Morphology at High Redshift
2014The morphology of galaxies at high redshift ranges from elliptical and spiral to clumpy, including chains, clump clusters, doubles and tadpoles. Clumpy galaxies observed in the Hubble Ultra Deep Field at redshifts z = 1–5 contain star-forming complexes that are hundreds of times more massive than those forming in local galaxies, reflecting the more ...

Study of molecular gas in distant galaxies during the last twenty years has followed the steady progress in mm wave receiver sensitivity. In 1975, CO was detected in M 82, NGC 253, and several other galaxies with redshifts of a few hundred kms−1 (Rickard et al. 1975; Solomon & de Zafra 1975).
