The distribution of mean and fluctuating magnetic fields in the multiphase interstellar medium [PDF]

We explore the effects of the multiphase structure of the interstellar medium (ISM) on galactic magnetic fields. Basing our analysis on compressible magnetohydrodynamic simulations of supernova-driven turbulence in the ISM, we investigate the properties ...

Imprints of the Local Bubble and Dust Complexity on Polarized Dust Emission

The Astrophysical Journal
Using 3D dust maps and Planck polarized dust emission data, we investigate the influence of the 3D geometry of the nearby interstellar medium (ISM) on the statistics of the dust polarization on large ( $80^{\prime} $ ) scales.

Magnetic fields around evolved stars [Elektronisk resurs]

, 2018
There has long been evidence of magnetic fields in the extended envelopes of asymptotic giant branch (AGB) and red supergiant (RSG) stars. These stars are important contributors to the enrichment of the interstellar medium by dust and heavy elements ...

Theoretical Introduction to Galactic Magnetic Fields

, 2007
International audienceOur Galaxy is pervaded by strong magnetic fields, which, together with the ordinary matter (made of gas and dust) and the cosmic rays, form the three basic constituents of the interstellar medium. After briefly reviewing our current

Magnetic Fields in the Southern Coalsack and Beyond

The Astronomical Journal
Starlight polarimetry, when combined with accurate distance measurements, allows for exploration of the three-dimensional structure of local magnetic fields in great detail.

Applying the Velocity Gradient Technique in NGC 1333: Comparison with Dust Polarization Observations

The Astrophysical Journal
Magnetic fields ( B -fields) are ubiquitous in the interstellar medium (ISM), and they play an essential role in the formation of molecular clouds and subsequent star formation.

Deterministic Propagation of Suprathermal Ions Through the Heliosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The PEPSSI instrument onboard New Horizons is sampling the energy range that bridges pickup and suprathermal He+ ${\mathrm{H}\mathrm{e}}^{+}$ ions for the first time in the outer heliosphere. New Horizons repeatedly encountered structures beyond 30 au that we interpret as the spiral of a corotating interaction region (CIR) for an extended ...

Slope of Magnetic Field–Density Relation as an Indicator of Magnetic Dominance

The Astrophysical Journal
The electromagnetic field is a fundamental force in nature that regulates the formation of stars in the Universe. Despite decades of efforts, a reliable assessment of the importance of the magnetic fields in star formation relations remains missing.
