Hubble spots most distant single star ever seen, at a record distance of 28 billion lightyears

With a fortuitous lineup of a massive cluster of galaxies, astronomers from among other institutes the University of Copenhagen and DTU discovered a single star across most of the entire observable Universe. This is the…

New research on how to quantify quantum effects on black holes

Professor in Physics, Vitor Cardoso from the Niels Bohr Institute, NBIA, has received a DNRF Chair grant from the Danish National Research Foundation to study and quantify quantum effects on astrophysical black holes

Black Hole Billiards in the Centers of Galaxies

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution, now…

New analysis leads to a fundamentally different view of supermassive black holes

In the center of most galaxies lies a supermassive black hole. Some of these are actively feeding on the gas and dust around them, expelling excess energy as powerful jets that are seen as quasars across the entire…

A novel way of investigating star-forming gas in the early Universe

Combining observations of exploding stars and observations of galaxies, astronomers at the Cosmic Dawn Center have found a novel way to estimate the amount of the otherwise invisible, cold gas in some of the first…

One in five galaxies in the early universe could still be hidden behind cosmic dust

Astronomers at the University of Copenhagen’s Cosmic Dawn Center have discovered two previously invisible galaxies billions of light-years away. Their discovery suggests that up to one in five such distant galaxies…

UCPH astronomers find six distant – and mysteriously dead – galaxies

Astronomers from the University of Copenhagen and the Technical University of Denmark (DTU), among others, have peered back 10-12 billion years into the universe and found six galaxies that mysteriously ran out of gas…

Astronomers see the same supernova three times — and predict a fourth to appear in 16 years

The enormous gravitation of a cluster of galaxies warps space to the extent that light from distant galaxies is deflected and brought to us from multiple directions. This effect has enabled astronomers from the…
