Production of Magnetic Turbulence by Cosmic Rays Drifting Upstream of Supernova Remnant Shocks

Jacek Niemiec, Martin Pohl, Thomas Stroman +1

We present results of 2D and 3D PIC simulations of magnetic turbulence production by isotropic cosmic-ray ions drifting upstream of SNR shocks. The studies aim at testing recent pr…

Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors

C. Galbiati, R. Purtschert

We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39…

Magnetic turbulence production by streaming cosmic rays upstream of SNR shocks

Jacek Niemiec, Martin Pohl

We present preliminary results of Particle-In-Cell simulations of magnetic turbulence production by isotropic cosmic-ray ions streaming upstream of supernova remnant shocks. The st…

Search for ultra-high energy photons using air showers

Markus Risse, Piotr Homola

The observation of photons with energies above 10^18 eV would open a new window in cosmic-ray research, with possible impact on astrophysics, particle physics, cosmology and fundam…

The nuclear symmetry energy and stability of matter in neutron star

Sebastian Kubis

It is shown that behavior of the nuclear symmetry energy is the key quantity in the stability consideration in neutron star matter. The symmetry energy controls the position of cru…

Is dark matter present in NGC4736? An iterative spectral method for finding mass distribution in spiral galaxies

Joanna Jalocha, Lukasz Bratek, Marek Kutschera

An iterative method for reconstructing mass distribution in spiral galaxies using a thin disk approximation is developed. As an example, the method is applied to galaxy NGC 4736; i…
