Using the NOEMA observatory, an international team of scientists has measured the precise distances for a large (135 sources) sample of the brightest galaxies selected from surveys done with the Herschel telescope. Robust values of the distances were derived for all sources, based on the detection of at least two emission lines for each object, making it the largest sample of high-z galaxies with unambiguous redshifts to date, and doubling the number of Herschel galaxies with such measurements. The results are published in three papers that appeared this week in Astronomy & Astrophysics. Read here the full IRAM press release.
