At our department we study both the explosion at the end of a massive star's life and the radiation resulting from the interaction of explosion material with the surrounding medium. Long gamma-ray bursts have very high energies and are associated with these explosions. They can be observed across the Universe. 

SN 1987A in the Large Magellanic Cloud.

The remnant of this process, a neutron star or black hole, often radiates in radio waves, X-rays, and gamma-rays. This radiation is produced by the material accreted onto a disk surrounding the neutron star or black hole. We study these phenomena using ground based telescopes, satellites, and balloon-borne instruments.

A related research area at the department is the use of supernovae for cosmology and the study of the cosmic acceleration.

Much of this research is performed in collaboration with the Physics departments at Stockholm University and the Royal Institute of Technology (KTH) in the research environment of the Oskar Klein Centre.
