We present Atacama Large Millimeter/submillimeter Array observations of an intrinsically radio-bright (L 1.4 GHz = (1.7 ± 0.1) × 1025 W Hz−1) and infrared luminous (L IR ≈ 1013 L ⊙) galaxy at z = 2.6. The infrared-to-radio luminosity ratio, q = 1.8,... Read More about A magnified view of circumnuclear star formation and feedback around an active galactic nucleus at z = 2.6.

The galaxies found in optical surveys fall in two distinct regions of a diagram of optical colour versus absolute magnitude: the red sequence and the blue cloud, with the green valley in between. We show that the galaxies found in a submillimetre sur... Read More about The causes of the red sequence, the blue cloud, the green valley, and the green mountain.
