Max Planck Institute for Physics, Munich, Germany Postdoctoral Positions UHE Cosmic-Ray Physics / Gamma-Ray Astrophysics The Max Planck Institute for Physics is one of the world's leading research institutes, focused on particle and astroparticle physics from both an experimental and a theoretical perspective. Our research activities in astroparticle physics comprise participation in the gamma ray telescope MAGIC at La Palma Observatory, the future space mission EUSO, and the CRESST dark matter search at Gran Sasso. The Max Planck Institute for Physics invites applications for two Postdoctoral Positions in ultra-high-energy cosmic-ray physics and in high-energy gamma-ray astrophysics, to strengthen our EUSO and MAGIC groups. EUSO is an experiment for UHE cosmic-ray observations, looking down onto the earth's atmosphere with a wide angle telescope from the International Space Station. EUSO will achieve a 300-1000 times larger aperture than currently running experiments and measure with high precision UHE cosmic rays above the GZK energy. The total mass of target atmosphere is about 2000 giga-tons. Naturally, the experiment is sensitive to UHE neutrinos, too. MAGIC is the world's largest ground based Cherenkov telescope to study the deep universe with high energy gamma rays above 30 GeV. There are many observational targets, e.g. AGNs, GRBs, Pulsars, and SNRs. However, the scientific objectives are not only the study of astrophysical sources, but also the investigation of fundamental physics, such as the search for Dark Matter and tests of the validity of Lorentz invariance. The first telescope is operative since October 2003 and construction of the second telescope has already started. The position is limited to initially two years, with the possibility of an extension by another four years. Salary is according to the German federal pay scale (BAT). Candidates with an experimental background in cosmic-ray physics, gamma-ray physics or neighbouring fields, such as elementary particle physics and astrophysics, are encouraged to apply. Applications from women are particularly welcome. The Max Planck Society is committed to employing more handicapped individuals and especially encourages them to apply. Interested scientists should send their application (including a CV and list of publications) until the end of February 2004 and arrange for three recommendation letters to be received by the same date.
