Academic Career and Research Areas

Prof. Schönfelder`s main research field was MeV Gamma-Ray Astronomy. He has develloped a new, previously unknown telescope ( called Compton Telescope ) for observations at MeV - energies, first as balloon-born experiment and later as satellite experiment COMPTEL aboard NASA`s Compton Gamma-Ray Observatory GRO. After that he was Co-Principal Investigator of the satellite experiment SPI for high spectral resolution aboard ESA`s INTEGRAL mission. Since 1985 he has held the introductory lectures in Astrophysics (2hours/week) at the TUM, which he has completed by special lectures on selected topics. He was supervisor of 28 diploma and 20 PhD-students with exams at the TUM.

Prof. Schönfelder studied Physics in Göttingen and Kiel from 1959 to 1966. He finished his degree as Diploma physisist at the "Institut für Reine und Angewandte Kernphysik" in Kiel.From 1966 till 1969 he was PhD-student at the "MPI für Extraterrestrische Physik" (MPE) in Garching and got the degree in 1970 at the TUM. From 1970 till 1979 he was employee at MPE. His main field was Gamma-Ray Astronomy. In 1979 he became Dr. rer nat habil at the TUM. From 1980 till his retirement in 2004 he was head of the Gamma-Ray Group at MPE  as Senior Research Scientist (C3-position). In 1973 and in 1989 he visited science institutes in Cambridge/England and New Hampshire/USA for 3 and 2 monthes, respectively. Since1995 he is Professor for Experimental Physics at the TUM.
