Astrophysical magnetic fields and nonlinear dynamo theory

A Brandenburg, K Subramanian - Physics Reports, 2005 - Elsevier
The current understanding of astrophysical magnetic fields is reviewed, focusing on their
generation and maintenance by turbulence. In the astrophysical context this generation is …

Magnetic fields in clusters of galaxies

F Govoni, L Feretti - International Journal of Modern Physics D, 2004 - World Scientific
The existence of magnetic fields associated with the intracluster medium in clusters of
galaxies is now well established through different methods of analysis. Magnetic fields are …

Planck intermediate results-XLVI. Reduction of large-scale systematic effects in HFI polarization maps and estimation of the reionization optical depth

N Aghanim, M Ashdown, J Aumont… - Astronomy & …, 2016 - aanda.org
This paper describes the identification, modelling, and removal of previously unexplained
systematic effects in the polarization data of the Planck High Frequency Instrument (HFI) on …

The coherent magnetic field of the Milky Way

M Unger, GR Farrar - The Astrophysical Journal, 2024 - iopscience.iop.org
We present a suite of models of the coherent magnetic field of the Galaxy based on new
divergence-free parametric functions describing the global structure of the field. The model …

Revised equipartition and minimum energy formula for magnetic field strength estimates from radio synchrotron observations

R Beck, M Krause - Astronomische Nachrichten: Astronomical …, 2005 - Wiley Online Library
The commonly used classical equipartition or minimum‐energy estimate of total magnetic
fields strengths from radio synchrotron intensities is of limited practical use because it is …

Observations of extended radio emission in clusters

C Ferrari, F Govoni, S Schindler, AM Bykov… - Clusters of Galaxies …, 2008 - Springer
We review observations of extended regions of radio emission in clusters; these include
diffuse emission in 'relics', and the large central regions commonly referred to as 'halos'. The …

Magnetic fields in spiral galaxies

R Beck - The Astronomy and Astrophysics Review, 2016 - Springer
Radio synchrotron emission, its polarization and Faraday rotation of the polarization angle
are powerful tools to study the strength and structure of magnetic fields in galaxies …

Map** the magnetic interstellar medium in three dimensions over the full sky with neutral hydrogen

SE Clark, BS Hensley - The Astrophysical Journal, 2019 - iopscience.iop.org
Recent analyses of 21 cm neutral hydrogen (H i) emission have demonstrated that H i gas is
organized into linear filamentary structures that are preferentially aligned with the local …

The millennium Arecibo 21 centimeter absorption-line survey. IV. Statistics of magnetic field, column density, and turbulence

C Heiles, TH Troland - The Astrophysical Journal, 2005 - iopscience.iop.org
We discuss observations of the magnetic field, column density, and turbulence in the cold
neutral medium (CNM). The observed quantities are only indirectly related to the intrinsic …

[PDF][PDF] Magnetic fields in the Milky Way and in galaxies

R Beck, R Wielebinski - Planets, stars and stellar systems, 2013 - scholar.archive.org
Most of the visible matter in the Universe is ionized, so that cosmic magnetic fields are quite
easy to generate and due to the lack of magnetic monopoles hard to destroy. Magnetic fields …
