DR. BRIAN LACKI
On Tuesday, January 21, 2014, Dr. Brian Lacki from Princeton University New Jersey, USA will give a talk on "Storm and Stress: Supernova-Driven Turbulence and the Chaotic Starburst ISM" starting at 10:15 am in NB 7/67.
Interested parties are welcome to attend!
Abstract: I explain my investigation into how supernovae power turbulence in the ISMs of starburst regions, and the implications for magnetic fields and cosmic rays. In weaker starbursts, supernovae blast open a hot (~40 MK) phase that escapes as a superwind. I calculate that supernovae can drive Mach ~ 1 turbulence in the hot wind. In the densest starbursts, like Arp 220, the volume is instead filled by cold molecular gas. Supernovae alone can drive turbulence in this gas to ~20 - 30 km/s, despite strong radiative losses. I predict magnetic field strengths of 70 microGauss in the Galactic Center starburst, 200 microGauss in NGC 253 and M82, and 2 milliGauss in Arp 220's nuclei. I show how supernova driving of turbulence naturally results in equipartition between several ISM phases in starbursts. I also discuss why CR diffusion may be very slow in these regions. Instead, turbulent mixing by the ISM may transport CRs, a very different process.

PROF. DR. FELIX SPANIER
On Thursday, January 9, 2014, Prof. Dr. Felix Spanier from North West University, Potchefstrom, South Africa will give a talk on "Turbulence and charged particle transport: recent advances in numerical simulations" starting at 10:15 am in NB 7/67. He is a guest of FOR 1048.
Interested parties are welcome to attend!
Abstract: The transport of high-energy charged particles in the turbulent plasmas of the heliosphere and the interstellar medium is one of the key problems in cosmic ray physics. Understanding the transport process by means of analytical calculations by the extreme complexity of the non-linear wave-particle interaction charged particles undergo.
In the past many attempt have been undertaken to perform numerical simulations of the transport of charged particles. Most of these attempt have been using artificial turbulence. I will show now our recent model combining incompressible MHD simulations with test particle transport.
I will especially focus on the problems associated with deciphering the pitch-angle diffusion from the tracks of test particles in a turbulent plasma.

DR. DAVIDE MARIOTTI
Dr. Davide Mariotti visited on 16th of October 2013 the group Coupled Plasma-Solid State Systems of Jun.-Prof. Dr. Jan Benedikt. This visit was organized in the frame of Leverhulme Trust lnternational Network Collaboration: "Materials processing by atmospheric pressure plasmas for energy applications", which was awarded to Dr. Mariotti last year and which supports the exchange of knowledge between University of Ulster of Coleraine, Ruhr-University Bochum, Institut Jean Lamour (Nancy), and National Institute of Advanced Industrial Science (Tokyo). Reciprocal visit in Ulster and Nancy has also been organized in the year 2013. Additionally, the PhD candidate Barbara Barwe (on the photo) could visit the group of Dr. Mariotti for one week in July 2013. The collaboration activities concentrate mainly on the development of atmospheric pressure plasma sources for generation of nanoparticles.
