Prof. Dr. Joachim Trümper

Prof. Dr. Joachim Trümper is one of the directors of the MPE and Honorary Professor of Astrophysics at the Ludwig Maximilians University of Munich since 1975. He holds a doctoral degree in physics from the Christian-Albrechts-University in Kiel (1959) where he worked as assistant Professor, Lecturer and Professor until 1971. His research subject at that time was the Cosmic Radiation at very High Energies. In 1969/70 he spent a sabbatical at MPE working with Profs. Lüst and Pinkau. At that time, he turned his attention to X-ray astronomy. In 1971 he accepted the chair in Astronomy at the Eberhard-Karls-University T\"ubingen where he started a high altitude balloon programme in X-ray astronomy, leading to the discovery of cyclotron lines in accreting neutron stars and many other results. In 1975 he accepted the call by the Max-Planck-Society and proposed the ROSAT project. Under his direction the X-ray astronomy group at MPE has been involved in many rocket and balloon experiments and the satellite observations EXOSAT, Mir-HEXE, ROSAT, BeppoSAX, Chandra, XMM and Spektrum-X.

Research interests:

  • The physics of neutron stars
  • Cosmological evolution of active galaxies
