Revisiting Acceleration of Charged Grains in Magnetohydrodynamic Turbulence

Thiem Hoang, A. Lazarian, R. Schlickeiser

We study the acceleration of charged grains by magnetohydrodynamics (MHD) turbulence in the interstellar medium (ISM). We begin with revisiting gyroresonance acceleration by taking…

An improved map of the Galactic Faraday sky

N. Oppermann, H. Junklewitz, G. Robbers +28

We aim to summarize the current state of knowledge regarding Galactic Faraday rotation in an all-sky map of the Galactic Faraday depth. For this we have assembled the most extensiv…

Basic Properties of MHD Turbulence in the Inertial Range

Andrey Beresnyak

We revisit the issue of spectral slope of MHD turbulence in the inertial range and argue that numerics favor Goldreich-Sridhar -5/3 slope rather than -3/2 slope. We also did precis…

Universal Nonlinear Small-Scale Dynamo

Andrey Beresnyak

We consider astrophysically relevant nonlinear MHD dynamo at large Reynolds numbers (Re). We argue that it is universal in a sense that magnetic energy grows at a rate which is a c…

Tracing the sources of cosmic rays with molecular ions

J. K. Becker, J. H. Black, M. Safarzadeh +1

The rate of ionization by cosmic rays in interstellar gas directly associated with gamma-ray emitting supernova remnants is for the first time calculated to be several orders of ma…

The large scale magnetic field structure of the spiral galaxy NGC 5775

Marian Soida, Marita Krause, Ralf-Jürgen Dettmar +1

In order to better determine the large-scale 3D-structure of magnetic fields in spiral galaxies we present a Faraday rotation analysis of the edge-on spiral galaxy NGC 5775. Deep r…
