New insights into gamma-ray Burst afterglows

Gamma-ray bursts are powerful bursts of gamma radiation in connection with the explosive death of massive stars. The bursts themselves are short lived – typically less than a few minutes, but is followed by an afterglow…

Cosmic collision creates mini-planet with rings

Until now, rings of material in a disc have only been observed around giant planets like Jupiter, Uranus, Neptune and especially Saturn, which is known for its spectacular rings. Now astronomers from NBI, have observed…

Unavoidable disorder used to build nanolaser

Researchers at NBI have discovered that imperfect nanostructures can offer entirely new functionalities. They have shown that imperfect optical chips can be used to produce ‘nanolasers’, which is an ultimately compact…

Ultra sensitive detection of radio waves with lasers

When detecting radio waves ‘noise’ in the instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means…

Stream of stars in Andromeda satellite galaxy shows cosmic collision

The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from NBI, among others, have detected a stream of stars in one of the Galaxy’s outer satellite galaxies, called Andromeda II.
