  • Young, star-forming galaxies can be characterized by their strong Lyman-α emission. An overdensity of such a population in one region of the sky is believed to mark a forming proto-cluster. An enhancement of submillimetre galaxies near the core of this proto-cluster, and a large-scale correlation between the submillimetre galaxies and the low-mass Lyman-a emitters suggests synchronous formation of the two different types of star-forming galaxies.

  • Submillimetre surveys have discovered a population of luminous, high-redshift, dusty starburst galaxies, which go through a phase of very rapid star formation, resulting in approximately equal extragalactic optical and far infrared backgrounds (FIRB). Devlin et al. report an extragalactic survey at 250, 350 and 500 µm; they determine that all of the FIRB comes from individual galaxies, with galaxies at redshift z ≥ 1.2 accounting for 70 per cent of it.

  • This paper reports the detection of a high-redshift galaxy that may be more representative of ‘normal’ star-forming galaxies formed in the first billion years of the Universe than the extreme starbursts discovered to date.
