Prof. Dr. habil. Roland Diehl

Prof. Dr. habil. Roland Diehl is research scientist at the Max Planck Institut für extraterrestrische Physik (MPE). He holds a doctoral degree in physics from the Technische Universität München (1988). He received his habilitation in 1998, and is Professor (apl.) in the Physics Department at the Technische Universität München. He started his career from nuclear physics (diploma at the Mainz Linear Accelerator lab in Mainz 1976), joining the staff of the gamma-ray astronomy group at MPE in 1979. Experimental nuclear physics determined his work and interest; then he has been taking part in development of pioneering telescopes for the MeV regime of astronomy at MPE, specifically the COMPTEL telescope operated 1991-2000 in space aboard NASA's Compton Gamma-Ray Observatory, and the SPI imaging spectrometer aboard ESA's INTEGRAL satrellite observatory launched in 2002 and operating successfully since. He lead the calibrations of the COMPTEL telescope, and furthers adequate analysis methods required for these complex measurements with gamma-ray telescopes. He is Co-Principal Investigator of the INTEGRAL SPI telescope. He is member of several international and national advisory boards, and of the Senate of the Max-Planck Society. His astrophysical interest is focused on nuclear astrophysics, interpreting gamma-ray line measurements in their context of nucleosynthesis in stars and supernovae, and related cosmic ray physics. He pioneered the imaging of the sky in the radioactive-decay gamma-ray line from 26Al, and is icurently involved in studies of supernovae, massive stars, novae, and the interstellar medium, employing a broad range of astronomical measurements.

Research interests:

  • Nuclear astrophysics and gamma-ray line measurement
  • Cosmic nucleosynthesis sources and processes
  • Stellar evolution, massive stars
  • Stellar explosions and their remnants: supernovae, GRBs, novae, X-ray bursts
  • The interstellar medium, including cosmic rays
  • Design, calibration, and data analysis of telescopes for cosmic gamma rays
