Super-bright supernova with extreme burst of gamma radiation

Astronomers from DARK have observed a super-bright supernova association with a very unusual long lasting gamma-ray burst. Gamma-ray bursts are in rare cases observed in connection with supernovae, which are the

Anja Andersen gives this year's Rosseland Lecture

April 8th 2015, Anja Andersen gave this year's Rosseland lecture about her research at DARK about cosmic dust in the interstellar medium. The Rosseland Lecture is held annually by the Institute of Theoretical…

Astronomers observe four images of the same supernova using a cosmic lens

Astronomers have for the first time observed a supernova multiply-imaged due to gravitational lensing. It is published in the scientific magazine Science in a special issue celebrating the centenary of Einstein’s Theory…

Astronomers find dust in the early universe

Dust plays an extremely important role in the universe – both in the formation of planets and new stars. But the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from…

Snapshot of cosmic burst of radio waves

A strange phenomenon has been observed by astronomers right as it was happening – a ‘fast radio burst’. The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe.

Using supermassive black holes to measure cosmic distances

One of the major problems in astronomy is measuring very large distances in the universe. Research from DARK shows that precise distances can be measured using supermassive black holes. The results are now published in…

Mystery of dwarf galaxy could be ejected black hole

Astronomers have observed a mysterious pheno- menon, which could be a massive black hole that has been ejected into space in connection with two galaxies colliding. This may be due to gravitational waves from the…
