- 28 January 2010
We use new multiwavelength radio observations, made with the VLA and Effelsberg telescopes, to study the magnetic field of the nearby galaxy M51 on scales from 200 pc to several kpc. Interferometric…
A SURVEY OF EXTRAGALACTIC FARADAY ROTATION AT HIGH GALACTIC LATITUDE: THE VERTICAL MAGNETIC FIELD OF THE MILKY WAY TOWARD THE GALACTIC POLES
- S. A. Mao, B. Gaensler, P. Kronberg
- Physics
- 23 March 2010
We present a study of the vertical magnetic field of the Milky Way toward the Galactic poles, determined from observations of Faraday rotation toward more than 1000 polarized extragalactic radio…
Evolving turbulence and magnetic fields in galaxy clusters
- K. Subramanian, A. Shukurov, N. Haugen
- Physics
- 7 May 2005
We discuss, using simple analytical models and magnetohydrodynamic (MHD) simulations, the origin and parameters of turbulence and magnetic fields in galaxy clusters. Any pre-existing tangled magnetic…
Structures in the rotation measure sky

- Physics
- 1 August 2001
Coherent structures in the distribution of the Faraday rotation measure (RM) of extragalactic radio sources are isolated using wavelet transformation techniques. A new algorithm of wavelet analysis…

Galactic dynamo and helicity losses through fountain flow
- A. Shukurov, D. Sokoloff, K. Subramanian, A. Brandenburg
- Physics
- 23 December 2005
Aims. Nonlinear behaviour of galactic dynamos is studied, allowing for magnetic helicity removal by the galactic fountain flow. Methods. A suitable advection speed is estimated, and a one-dimensional…
MODELING THE MAGNETIC FIELD IN THE GALACTIC DISK USING NEW ROTATION MEASURE OBSERVATIONS FROM THE VERY LARGE ARRAY
- Cameron Van Eck, Jo-Anne C. Brown, N. McClure–Griffiths
- Physics
- 14 December 2010
We have determined 194 Faraday rotation measures (RMs) of polarized extragalactic radio sources using new, multi-channel polarization observations at frequencies around 1.4 GHz from the Very Large…
MAGNETIC FIELDS IN A SAMPLE OF NEARBY SPIRAL GALAXIES
- Cameron Van Eck, Jo-Anne C. Brown, A. Shukurov, A. Fletcher
- Physics
- 5 November 2014
Both observations and modeling of magnetic fields in the diffuse interstellar gas of spiral galaxies are well developed, but the theory has been confronted with observations for only a handful of…
