The formation of cluster elliptical galaxies as revealed by extensive star formation
Article Abstract:
Research reveals that the synchronous formation of the luminous elliptical galaxies occurs at the centres of galaxy clusters as indicated by the prevalence, orientation, and masses of the submillimetre companion galaxies. Data on the submillimetre mapping of seven high-redshift radio galaxies confirm the regions of massive star-formation activity in the radio galaxies.

A median redshift of 2.4 for galaxies bright at submillimetre wavelengths
Article Abstract:
Study of submillimetre galaxies is difficult due to the dust clouds that obscure emitted light. Analysis of spectroscopic redshifts for ten submillimetre galaxies discovered by radio telescopes shows a median redshift of 2.4, indicating that due to their extreme density, they are an important component of star formation at high redshift.

Rapid growth of black holes in massive star-forming galaxies
Article Abstract:
A report on the ultra-deep X-ray observations of distant star-forming galaxies that are bright at submillimetre wavelengths is presented. The findings show that the black holes in these galaxies are growing almost continuously throughout periods of intense star formation.
