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

Ancient ice reveals scores of gigantic volcanic eruptions

Ice cores drilled in Antarctica and Greenland have revealed gigantic volcanic eruptions during the last ice age. Sixty-nine of these were larger than any eruption in modern history. According to the University of…

Past global photosynthesis reacted quickly to more carbon in the air

Ice cores allow climate researchers to look 800,000 years back in time: atmospheric carbon acts as fertilizer, increasing biological production. The mechanism removes carbon from the air and thereby dampens the…

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…

Breakthrough of the year

Our team at the Quantum Optics group (QUANTOP) at the Niels Bohr Institute has applied the basic principle behind these achievements for quantum entanglement between very distant and different quantum objects,” says…

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…
