@article{Watson2015ADN, title={A dusty, normal galaxy in the epoch of reionization}, author={Darach Watson and Lise Christensen and Kirsten K. Knudsen and Johan Richard and Anna R. Gallazzi and Michał Jerzy Michałowski}, journal={Nature}, year={2015}, volume={519}, pages={327-330} }
Candidates for the modest galaxies that formed most of the stars in the early Universe, at redshifts z > 7, have been found in large numbers with extremely deep restframe-ultraviolet imaging. But it has proved difficult for existing spectrographs to characterize them using their ultraviolet light. The detailed properties of these galaxies could be measured from dust and cool gas emission at far-infrared wavelengths if the galaxies have become sufficiently enriched in dust and metals. So far…

It is concluded that the contribution of dust-obscured galaxies to the cosmic star formation rate density at z’s greater than 6 is sub-dominant and this population of heavily dust-OBscuring galaxies appears to contribute 10-25% to the z > 6 cosmic starformation rate density.

It is found that nine typical star-forming galaxies about one billion years after the Big Bang have thermal emission that is less than 1/12 that of similar systems about two billion years later, and enhanced [C ii] emission relative to the far-infrared continuum, confirming a strong evolution in the properties of the interstellar medium in the early Universe.

Despite the overall downturn in cosmic star formation towards the highest redshifts, it seems that environments mature enough to form the most massive, intense starbursts existed at least as early as 880 million years after the Big Bang.

A deep near-infrared spectroscopic survey of 43 photometrically-selected galaxies with z > 6.5 finds a surprisingly high star-formation rate of about 330 solar masses per year, which is more than a factor of 100 greater than that seen in the Milky Way.

A spectroscopic redshift of z = 6.96 is reported for a galaxy whose spectrum clearly shows Lyman-α emission at 9,682 Å, indicating active star formation at a rate of ∼10M[circdot] yr-1, which demonstrates that galaxy formation was under way when the Universe was only ∼6 per cent of its present age.
