01.04.2009 - Besuch am INP Greifswald
Dr. Volker Schulz-von der Gathen and one of our students, Hendrik Bahre, visited with the INP in Greifswald in March 2009 for a one week research activity. In cooperation with Dr. R. Foest and Dr. H. Lange, they investigated the VUV emission of the RUB micro plasma jet.
Results of this cooperation will be presented at the ISPC 19 conference in Bochum.
Julia Becker at the Cosmic Ray Conference in Lodz, Poland
At the Cosmic Ray Conference in Lodz, Poland (July 7-15, 2009), first results obtained by Jun.-Prof. Dr. Julia Becker and Dr. Dreyer within the Research Department could be presented [1]. Furthermore, further steps could be discussed with internationally renowned scientists. More than 1000 physicists (plasma astrophysicists, astroparticle physicists and astrophysicists) participated in the conference.

Julia Becker an der Universität Göteborg
In Göteborg wurde ein Forschungsaufenthalt bei Prof. Dr. Marek Abramowicz durchgeführt. Mit Prof. Dr. Abramowicz arbeiten wir an einem gemeinsamen Projekt zur Untersuchung von Wechselwirkungen kleiner schwarzer Löcher mit stellaren Objekten. Was passiert, wenn ein kleines schwarzes Loch, welches selbst die Masse von einem Kometen oder einem Zwergplaneten besitzt, mit astrophysikalischen Plasmen kollidiert? Was passiert, wenn die Sterne sogar die kleinen schwarzen Löcher fressen? In dem Forschungsaufenthalt in Göteborg wurden erste Zwischenergebnisse zur Beantwortung dieser Fragen erzielt, ein Forschungsartikel und sowie ein populärwissenschaftlicher Artikel sind in Vorbereitung.
Julia Becker at the IceCube meeting in Berlin
IceCube is the most suitable instrument for observing neutrinos from astrophysical plasmas. The measurement of neutrinos is essential for understanding the structure of shocked plasmas that occur, for example, in supernova remnants, active galaxies, and gamma ray bursts. IceCube members meet every six months to discuss the status of the experiment, new analysis techniques, and the development of theoretical models of neutrino emission. As part of the Research Department, Jun.-Prof. Dr. Julia Becker's group participated in the meeting in Berlin (September 19-25, 2009). Here, Dr. Jens Dreyer was able to give a talk on the progress of his analysis on point source stacking and discuss both his analysis and the underlying theoretical models with other members of IceCube, including those from the USA, New Zealand, Japan, Switzerland, Sweden, Belgium, and Germany. Martino Olivo gave two talks on neutrino production in Gamma Ray Burst. A publication, also based on discussions that have been held in Berlin at the meeting, has now been submitted to "The Astrophysical Journal". For this, special discussions were held with Prof. Francis Halzen, head of the IceCube experiment. Julia Becker was Chair for the sessions on neutrino emission from Gamma Ray Bursts and was able to have further discussions on neutrino production in shocked plasmas with various members of IceCube.
