Faraday Signature Of Magnetic Helicity From Reduced Depolarization

div>AXEL BRANDENBURG AND RODION STEPANOV FARADAY SIGNATURE OF MAGNETIC HELICITY FROM REDUCED DEPOLARIZATION (PREPRINT) Abstract: Using one-dimensional models, we show that a helical magnet ic field with an appropriate sign of a helicity can compensate the Faraday depolarization resulting from the superposition of Faraday-rotated polarization planes from a spatially extended source. For radio emission from Continue Reading

An observational test for correlations between cosmic rays and magnetic fields

R.Stepanov, A. Shukurov, A. Fletcher, R. Beck, L. La Porta and F. Tabatabaei An observational test for correlations between cosmic rays and magnetic fields// MNRAS, 2014 437 (3): 2201-2216. (DOI http://mnras.oxfordjournals.org/content/437/3/2201) Abstract: We derive the magnitude of fluctuations in total synchrotron intensity in the Milky Way and M33, from both observations and theory under various Continue Reading
