Nucleosynthesis for a Life
A symposium in honour of R. Diehl


Please join us for a retirement symposium to honor Prof. Roland Diehl on Friday, February 8th, 2019.

Roland started his career in nuclear physics (diploma at the Mainz Linear Accelerator Lab), before joining the gamma-ray astrophysics group at MPE in 1979(!). Based on a balloon flight of MPE's Compton telescope in Brazil in 1982, he derived the first imaging result of the 26Al 1.8 MeV line from the Galactic Center. This measurement, and more generally experimental nuclear physics and astrophysics, has determined his scientific life since then. Leading the calibration of the COMPTEL telescope, he became quickly known as Mr. "1.8 MeV line" with the meanwhile famous 26Al map of the sky. With the launch of ESA's INTEGRAL satellite he widened his interest to other nuclear lines in astrophysics, and soon became the expert in nuclear astrophysics in Germany. He has always pushed for improving the data analysis methods required for the complex measurements in the gamma-ray domain.
Roland has engaged himself in a variety of occasions. He has (co-)organized numerous conferences worldwide, and contributed in concerted activities to promote nuclear astrophysics at the European and international level. For more than 20 years he is teaching high-energy astrophysics at the Technical University Munich to maintain a healthy influx of knowlegable young scientists into his field of research. As part of the Munich Cluster of Excellence "Origin and Evolution of the Universe" he has been deputy coordinator of Research Area G on the "Origin of the Heavy Elements and Chemical Evolution". He edited and co-authored a book on "Astrophysics with Radioactive Isotopes" which just has been updated and extended in a second edition. And far beyond his field of expertise Roland has engaged for the benefit of all scientists at MPE as an elected representative of the institute at the Chemical-Physical-Technical (CPT) Section of the Max-Planck Society for two periods, and for a substantial fraction of this time even as elected representative of the CPTS to the Senat of MPG.

We will hold a day-long scientific symposium at the Max-Planck Institute of extraterrestrial Physics on Friday, February 8th, 2019 (new seminar room, 1.1.18). There are no conference fees, but we ask that you register by sending an email to J. Greiner
