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…

Mars has belts of glaciers consisting of frozen water

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the…

Super sensitive measurement of magnetic fields in swinging atoms

There are electrical signals in the nervous system, the brain and throughout the human body and there are tiny magnetic fields associated with these signals that could be important for medical science.

A.P. Møller Foundation donates 25 million kroner to ice core research

Professor Dorthe Dahl-Jensen, head of the Centre for Ice and Climate at NBIhas received a grant of 25 million kroner from the A.P. Møller Foundation for a major new research project in Greenland.

Planets in the habitable zone around most stars, calculate researchers

Astronomers have discovered thousands of exoplanets in our galaxy, the Milky Way. By analysing these planetary systems, researchers from the Australian National University and the Niels Bohr Institute in Copenhagen have…

Quantum link between QDev in Denmark and QuTech in Holland

The Center for Quantum Devices, QDev at the Niels Bohr Institute at the University of Copenhagen and QuTech at Delft University of Technology in Holland have therefore entered into an international partnership in the…

CERN starting the LHC accelerator up again to solve new mysteries

The 27 km long subterranean particle accelerator, the LHC (Large Hadron Collider) at CERN is ready to start up again. The LHC is the largest and most powerful particle accelerator in the world. After a break of two…

Quantum mechanic frequency filter for atomic clocks

In an atomic clock, electrons jumping from one orbit to another decides the clock’s frequency. To get the electrons to jump, researchers shine light on the atoms using stabilised laser light. However, the laser light ha…

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. The light from the supernova is seen in four different images due to a cosmic phenomenon that causes light to be…

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…

Jan W. Thomsen receives annual teaching award at NBI

“For more than five years, Jan Thomsen has captivated class after class as he takes students on a journey into the world of optics,” reads the justification from the students for recommending Jan Thomsen for the Niels…

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.

New superconducting hybrid crystals developed at the University of Copenhagen

A new type of ‘nanowire’ crystals that fuses semiconducting and metallic materials on the atomic scale could lay the foundation for future semiconducting electronics. Researchers at the University of Copenhagen are…

Atoms queue up for quantum computer networks

In order to develop future quantum computer networks, it is necessary to hold a known number of atoms. To do this, researchers from NBI have developed a method with a trap that captures the atoms along an ultra thin…
