Supernovae, Gamma-ray Bursts and Compact Objects
Massive stars end their lifes in gigantic explosions, supernovae. Sometimes these explosions also result in gamma-ray bursts. The end results are newly synthesized elements, neutron stars and black holes.
At our department we study both the explosion itself and the radiation resulting from the interaction with the surrounding medium. A well-studied example is SN 1987A. The gamma-ray bursts are even more energetic and can be observed across the Universe.
The remnants in the form of a neutron star or a black hole often give rise to radiation in the radio, X-ray and gamma-ray ranges. This is caused by the material accreted onto the compact object. We study these phenomena by ground based telescopes, satellites and balloon 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 strong research environment of the Oskar Klein Centre.
