Can the Dynamo of Spiral-arm Galaxies Be Explained by Anisotropic Conductivity?
The Astrophysical JournalThe possibility of generating a magnetic field by a dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically and experimentally.

Anisotropic Velocity Fluctuations in Galaxy Mergers: A Probe of the Magnetic Field
The Astrophysical JournalMagnetic fields and turbulence are fundamental to the evolutions of galaxies, yet their precise measurement and analysis present significant challenges.

The Astrophysical Journal Letters, 2023 Faraday rotation measures (RMs) of fast radio bursts (FRBs) offer the prospect of directly measuring extragalactic magnetic fields. We present an analysis of the RMs of 10 as yet nonrepeating FRBs detected and localized to host galaxies with robust ...

Cosmological Phase Transitions—EWPT-QCDPT: Magnetic Field Creation
Magnetochemistry, 2022 We review the cosmic microwave background (CMBR) estimate of ordinary matter, dark matter and dark energy in the universe. Then, we review the cosmological electroweak (EWPT) and quantum chromodynamics (QCDPT) phase transitions.

Magnetic fields in nearby galaxies [PDF]
Proceedings of Panoramic Radio Astronomy: Wide-field 1-2 GHz research on galaxy evolution — PoS(PRA2009), 2010 We describe a recent full-polarization radio continuum survey, performed using the Westerbork Synthesis Radio Telescope (WSRT), of several nearby galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The WSRT-SINGS survey has been utilized to study the polarized emission and Faraday rotation measures (RMs) in the targets, and reveals ...

Magnetic Fields in Irregular Galaxies [PDF]
Highlights of Astronomy, 2002 AbstractRadio data of large irregular galaxies reveal some extended synchrotron emission with a substantial degree of polarization. In the case of NGC 4449 strong galaxy-scale regular magnetic fields were found, in spite of the lack of ordered rotation required for the conventional dynamo action.

A Three-dimensional Model for the Reversal in the Local Large-scale Interstellar Magnetic Field
The Astrophysical JournalWe probe the three-dimensional geometry of the large-scale Galactic magnetic field within 1 kpc of the Sun using the Dominion Radio Astrophysical Observatory Global Magneto-Ionic Medium Survey (GMIMS) of the Northern Sky (DRAGONS).
