Radio- og mikrobølger afslører galaksers sande natur i det tidlige Univers
Ved hjælp af radioteleskoper over hele verden har et hold af astronomer fra Cosmic Dawn Center, København, opdaget adskillige galakser i det tidlige Univers, som har været skjult for os på grund af enorme mængder af støv. Observationerne gjorde det muligt for holdet at måle støvets tæthed og temperatur, hvilket viste, at denne type galakser bidrog væsentligt til Universets samlede stjernedannelse, da det kun var 1/10 af sin nuværende alder.

Radio- and microwaves reveal the true nature of dark galaxies in the early Universe
Utilizing multiple radio telescopes across the world, a team of astronomers from the Cosmic Dawn Center, Copenhagen, have discovered several galaxies in the early Universe that, due to massive amounts of dust, were hidden from our sight. The observations allowed the team to measure the temperature and thickness of the dust, demonstrating that this type of galaxies contributed significantly to the total star formation when the Universe was only 1/10 of its current age.
