Extremely energetic particles coupled with the violent death of a star for the first time

Researchers at the Niels Bohr Institute, University of Copenhagen and DTU Space in Lyngby have determined the emission of extremely energetic light particles during the death of a very heavy star for the first time.

The final piece in the puzzle of the origin of the elements

For the first time, an element heavier than iron has been clearly detected in the collision of two neutron stars, resolving one of the fundamental questions about the history of the universe.

Record breaking observations find most remote protocluster of galaxies, linking dark matter to galaxy formation

An international team of astronomers with participation by researchers from DAWN has discovered a protocluster of galaxies 13.0 billion light years away using the Subaru, Keck, and Gemini Telescopes in Hawaii.

NSF Awards Funding for the IceCube Upgrade

The IceCube Neutrino Observatory is about to get a significant upgrade. The World's largest neutrino telescope, located at the South Pole, is run by an international team of more than 300 scientists, including a group a…

Greenland Telescope to image black holes by moving onto the Greenland ice sheet

Scientists from DARK at the Niels Bohr Institute will soon be able to participate in the “Event Horizon Telescope” (EHT) with the Greenland Telescope (GLT). The GLT will become part of a global network of radio…

Catching a glimpse of the gamma-ray burst engine

A gamma-ray burst registered in December of 2017 turns out to be “one of the closets GRBs ever observed”. The discovery is featured in Nature – and it has yielded valuable information about the formation of the most…

Hubble searches for the origin of the first galaxies

How did the first galaxies come to be? The Buffalo project, a new Hubble Frontier Fields Program to study the first galaxies with the The Hubble Space Telescope has started to conduct a large survey.

New observations link gigantic star collisions to homeless short duration gamma ray bursts

Scientists from the Niels Bohr Institute, University of Copenhagen, have been involved in detecting a beam of light that provides a link between neutron star mergers and short duration gamma ray bursts. The result is no…

Here is what it looks like, when a massive black hole devours a star

Jane Lixin Dai and Professor Enrico Ramirez from DARK Cosmology Centre at the Niels Bohr Institute have recently provided the scientific community with a much-needed computer model.

New discovery: Supernova explodes several times

Astronomers have for the first time discovered a star that exploded multiple times over a period of more than fifty years. These observations are challenging existing theories on cosmic catastrophes.
