404. Beaming of particles and synchrotron radiation in relativistic magnetic reconnection at high magnetizations

Dr Daniel Kagan (Tel Aviv University)

Workshop, August 10-14

Oral

We investigate the beaming of particles and the resulting synchrotron radiation in relativistic reconnection with background magnetizations of 4, 40, and 400 via 2D particle-in-cell simulations. First, we verify that the overall rate of energy conversion and the characteristics of radiation are similar at all magnetizations even for configurations including low-density background plasmas,...

Workshop, August 10-14

Oral

Magnetic reconnection is a very efficient process to convert magnetic energy into kinetic plasma energy. Unfortunately, models of reconnection such as Sweet Parker, do not agree with the time scale observed during the impulsive phase of a Solar flares, providing only small reconnection rates. One possible approach for reaching fast reconnection observed is by considering small...

393. Reconnection in Vlasiator: 2. Influence of the magnetosheath waves

Sanni Hoilijoki (Finnish Meteorological Institute)

14/08/2015, 12:00

Workshop, August 10-14

Oral

The global hybrid-Vlasov simulation Vlasiator (http://vlasiator.fmi.fi), developed at the Finnish Meteorological Institute, describes ions as velocity distributions functions propagated by solving the Vlasov equation and treats electrons as charge-neutralizing fluid. We present results from a new 5- dimensional simulation describing the Earth's magnetosphere in two dimensions in...
