TL;DR: In this paper, the authors used the SPIRE instrument on the Herschel Multi-tiered Extra-Galactic Survey (HerMES) to directly resolve ~15% of the infrared extra-galactic background at the wavelength near where it peaks.

TL;DR: Submillimetre and X-rays observations show that rapid star formation was common in the host galaxies of AGN when the Universe was 2–6 billion years old, but that the most vigorous star formation is not observed around black holes above an X-ray luminosity of 1044 ergs per second.

TL;DR: In this article, the authors determined the ratio, q(IR), of rest-frame 8-1000um flux to monochromatic radio flux, S(1.4GHz), for galaxies selected at far-IR and radio wavelengths, to search for signs that the ratio evolves with redshift, luminosity or dust temperature.

TL;DR: In this article, the spectral energy distribution (SED) and dust temperature of galaxies have strongly evolved since z~2.5, which may either result from stronger broad emission lines or warm dust continuum heated by a hidden AGN.

TL;DR: In this paper, the authors derived the number counts and redshift distributions of the bright SPIRE sources in the COSMOS field with a method using the positions, the flux densities, and the redshifts of the 24 μm sources as a prior.
