Astronomer finder en sværm af galakser i kredsløb omkring en hyper-lysstærk galakse
Ved hjælp af Very Large Telescope og radioteleskopet ALMA i Chile har et hold af astronomer med deltagelse fra Niels Bohr Institutet opdaget en sværm af galakser rundt omkring en hyper-lysstærk og stærkt stjernedannende galakse i det tidlige Univers. Observationen giver et vigtigt indblik i, hvordan exceptionelt klare galakser vokser, og hvordan de udvikler sig til energirige kvasarer, som stråler tværs gennem det meste af det observerbare Univers.

Astronomers discover a swarm of galaxies orbiting a hyper-luminous galaxy
Using the Very Large Telescope and the radio telescope ALMA in Chile, a team of astronomers including researchers from the Niels Bohr Institute has discovered a swarm of galaxies orbiting the surroundings of a hyper-luminous and vigorously star-forming galaxy in the early Universe. The observation provides important clues to how exceptionally bright galaxies grow, and to how they evolve into energetic quasars, beaming light across most of the observable Universe.

Kasper Heintz receives EUR 207,000 from the Villum Foundation for building a new binocular telescope
Congratulations to Kasper Heintz, who has just been awarded a grant for building and installing two cameras at two different observatories. The cameras will enable astronomers to monitor short-lived astronomical phenomena such as stellar explosions, exoplanet transits, and Earth-impacting meteors.

Galaxies at Cosmic Dawn
Since the James Webb Space Telescope began releasing its science observations last month, candidates for increasingly distant galaxies have been reported on a regular basis. In fact, the size and the number of distant galaxies seem to challenge our understanding of how galaxies form, although there are many caveats and alternative explanations. Are we facing a cosmological paradigm shift, are we misinterpreting our data, or are the more mundane reasons? Astronomers at the Cosmic Dawn Center in Copenhagen are working intensely on solving this puzzle.
