  • Sorte huller hjalp med at kvæle stjernedannelse i det tidlige Univers

    Mens nogle galakser danner massevis af nye stjerner, dør andre ud og lever et mere passivt liv. Hvad der afholdt disse galakser fra at danne nye stjerner i en ung alder er ikke velforstået, bl.a. fordi de er så fjerne og lyssvage at de nødigt lader sig observere. Men ved at se på det samlede lys fra tusindvis af galakser er det nu lykkedes astronomer fra bl.a. Københavns Universitet at vise, at sorte huller hjalp til med at slukke for stjernedannelsen.

  • Black holes helped quenching star formation in the early Universe

    While some galaxies form stars at a continuous rate, others die out and lead a more passive life. What made these galaxies stop forming stars at an early age is not well established, not the least because they are so distant and faint that they evade being observed. But looking at the combined light from thousands of galaxies, a team of astronomers including the University of Copenhagen showed that black holes helped turn off star formation.

  • Danish astrophysics student discovers link between global warming and locally unstable weather

    Climate change gives rise to more unstable weather, local droughts and extreme temperature records, but a coherent theory relating local and global climate is still under active development. Now a Danish astrophysics student at the Niels Bohr Institute used a mathematical approach —inspired by research in the Universe’s light — to unveil how global temperature increase engenders locally unstable weather on Earth.

  • Dansk astrofysik-studerende finder forbindelse mellem global opvarming og vejrets ustabilitet

    Klimaforandringer danner grobund for mere ustabilt vejr, lokale tørker og ekstreme temperatur-rekorder, men en sammenhængende teori mellem det lokale og det globale klima er endnu under aktiv udvikling. Nu har en dansk studerende i astrofysik ved Niels Bohr Institutet brugt en matematisk tilgang — inspireret af forskning i Universets lys — til at afdække, hvordan globale temperaturstigninger frembringer lokalt ustabilt vejr på Jorden.
