Stefan Klepser is a scientist at DESY in Zeuthen near Berlin. He has participated in various astroparticle collaborations since 2003 and apart from particle detectors and cosmic accelerators, he relishes the community that is associated with it. Whether neutrinos at the South Pole, protons in the middle of nowhere, gamma-rays in the desert – nothing would be found without the astro-fantasizers, network-nerds, outdoor-physicists, algorithm-dealers and statistics-metalheads who getting the whole thing going. He is now leading a working group on gamma-ray astronomy and, recently, a project to modernize the H.E.S.S. telescopes in Namibia.
Stefan Ohm is a postdoc at DESY Zeuthen and works at H.E.S.S. as well as the Cherenkov Telescope Array (CTA). Themes, which are always slightly different, fascinate Stefan, that is why he originally came to astroparticle physics. For more than 10 years now, he has been active in this pretty recent field of research and is always trying to inspire people with the secrets of the extreme universe. Stefan Ohm studied and promoted in Heidelberg and is at DESY since 2014 after three-year of research in Leeds and Leicester (UK).
Eva Leser is a Ph.D. student at the University of Potsdam since the end of 2014 and is working on the High Energy Stereoscopic System (H.E.S.S.), an experiment composing of five Cherenkov telescopes for very high energy gamma radiation in Namibia. Eva Leser has studied in Dortmund and Berkeley (USA) and has been living in Berlin since 2014.
Anna Franckowiak has been working as a scientist at the DESY in Zeuthen since 2015. The astroparticle physicist studies the most energetic processes in the universe. In order to obtain an overall picture, she uses different messengers from the universe: of visible light, via high-energy gamma radiation to the elusive neutrinos. Therefor she works with optical telescopes, satellites wich are measure gamma radiation and the IceCube Neutrino Observatory at the South Pole. Since the beginning of 2017, she has been head of a Helmholtz junior research group at DESY. Anna Franckowiak, born in 1983, lives in Berlin and enjoys it to spread her scientific everyday life and exciting research results to a broad, interested audience.
Robert Brose has been a Ph.D student at the University of Potsdam since 2015. As a member of the Veritas-Collaboration and the astroparticle theory group at DESY, he is developing models for the acceleration of cosmic radiation in supernova remants. Since theoretical physics is, in his opinion, much more exciting than his reputation, he reports in the context of this blog of his scientist’s day.
