James Webb giver ny indsigt i galaksernes vækst og deres mørke stof
Kortlægning af en kosmisk historie: Et internationalt hold af forskere, ledet af astronomer på Cosmic Dawn Center i København, har udgivet et omfattende studie af, hvordan galakser og deres mørke stof udvikler sig henover det meste af Universets historie. Denne enestående undersøgelse afslører uforudsete tendenser i galaksernes masse, vækstrater og forholdet mellem deres stjerner og deres mørke stof. Studiet udfordrer eksisterende modeller af galaksedannelse og antyder en ny forståelse af, hvordan disse kolossale kosmiske strukturer opstod.

New insights into galaxy growth and dark matter from James Webb
Mapping cosmic history: An international team of researchers, led by astronomers at the Cosmic Dawn Center in Copenhagen, has released a comprehensive study on how galaxies and their dark matter have evolved across most of the history of the Universe. Spanning 11 billion years, this unprecedented survey reveals unexpected patterns in galaxy mass, growth rates, and the relationship between galaxies and dark matter. The study challenges existing models of galaxy formation and hints at a new understanding of how these immense cosmic structures emerged.

Webb giver nyt, detaljeret indblik i skabelsen af de første galakser
I løbet af de seneste par år har rumteleskopet James Webb revolutioneret vores forståelse af, hvordan de første stjerner og galakser blev dannet i det tidlige Univers. Nu har et internationalt team af forskere, ledet af astronomer fra Cosmic Dawn Center i København, publiceret det første storstilede studie af mere end 600 galakser, observeret indenfor den første milliard år efter Big Bang. Undersøgelsen flytter forskningsfeltet fra at studere de første få opdagelser med Webb, til at etablere store, statistiske datasæt af galakser. Studiet afslører, hvordan nogle af de tidligste galakser opsamler enorme mængder af ren, frisk gas fra deres omgivelser, et tegn på at vi nu ser galakser i færd med at blive dannet.

Webb provides a new detailed look into the formation of the first galaxies
In the past few years, the James Webb Space Telescope has revolutionized our understanding of how the first stars and galaxies formed in the early Universe. Now, an international team of researchers, led by astronomers at the Cosmic Dawn Center in Copenhagen, have published the first, large-scale study of more than 600 galaxies observed within the first billion years after the Big Bang. This survey moves the field from studying the first few discoveries with Webb, to establishing large, statistical samples of galaxies. Intriguingly, this study reveals how some of the earliest galaxies accrete massive amounts of pristine gas from their surroundings, a sign that we are now seeing the formation of galaxies in progress.
