EA Researcher Markus Voge successfully defended his doctoral thesis at the Physics Institute of the University of Bonn on Friday, 10 February 2017. The title of his thesis is “Searches for Neutrinos from Supernovae Using Cherenkov In-Ice Detectors”.

Supernovae mark the violent death of massive stars. They are among the most energetic processes known to exist in the universe. Neutrinos, electrically neutral elementary particles, play crucial roles in supernova processes. Besides the low-energy neutrinos emitted during the core-collapse process of the supernova, there may be neutrinos of much higher energies that are generated after the core-collapse.

In his thesis, Mr Voge has studied a new detector concept with sensitivity to extra-galactic supernova low-energy neutrino bursts. It enables the routine detection of supernova neutrinos several times per year instead of only one to three times per century. In addition, Mr Voge has carried out a multi-messenger data analysis programme, which registers high-energy neutrino bursts and triggers follow-up observations with optical telescopes.

 

Mr Voge conducted his doctoral thesis at the University of Bonn as a member of the international research collaboration IceCube. He has made use of the neutrino data from the IceCube detector located at the South Pole, which he combined with optical data from the Palomar Observatory in California.
