The Magnetized Disk-Halo Transition Region of M51
M. Kierdorf, S. A. Mao, A. Fletcher +5
An excellent laboratory for studying large scale magnetic fields is the grand de- sign face-on spiral galaxy M51. Due to wavelength-dependent Faraday depolarization, linearly polar…
Statistical properties of Faraday rotation measure from large-scale magnetic fields in intervening disc galaxies
Aritra Basu, S. A. Mao, Andrew Fletcher +5
To constrain the large-scale magnetic field strengths in cosmologically distant galax- ies, we derive the probability distribution function of Faraday rotation measure (RM) when ra…
Mean fields and fluctuations in compressible magnetohydrodynamic flows
J. F. Hollins, G. R. Sarson, C. C. Evirgen +3
We apply Gaussian smoothing to obtain mean magnetic field, density, velocity, and magnetic and kinetic energy densities from our numerical model of the interstellar medium, based o…
Reliable detection and characterization of low-frequency polarized sources in the LOFAR M51 field
A. Neld, C. Horellou, D. D. Mulcahy +14
The new generation of broad-band radio continuum surveys will provide large data sets with polarization information. New algorithms need to be developed to extract reliable catalog…
IMAGINE: A comprehensive view of the interstellar medium, Galactic magnetic fields and cosmic rays
Francois Boulanger, Torsten Ensslin, Andrew Fletcher +20
In this white paper we introduce the IMAGINE Consortium and its scientific background, goals and structure. Our purpose is to coordinate and facilitate the efforts of a diverse gro…
Topological data analysis and diagnostics of compressible MHD turbulence
Irina Makarenko, Paul Bushby, Andrew Fletcher +3
The predictions of mean-field electrodynamics can now be probed using direct numerical simulations of random flows and magnetic fields. When modelling astrophysical MHD, it is impo…
