Magnetic fields in the nearby Universe, as observed in solar and planetary realms, stars, and interstellar starforming nurseries

, 2011
Here I present a survey of planetary, stellar and clumpy interstellar magnetic fields, with an emphasis on discoveries made in the last decade. Ground-based and Earth-satellite observations of magnetic fields in astronomical objects are cataloged, as ...

Infrared polarimetry and the interstellar magnetic field

The Astrophysical Journal, 1989
Une bonne correlation entre la polarisation interstellaire et l'extinction interstellaire est trouvee a 2,2 μm pour toutes les lignes de visee. Un modele de champ magnetique interstellaire est presente, et montre qu'une contribution egale de la composante uniforme et de la composante aleatoire reproduit bien les ...

Tracing magnetic fields with the polarization of submillimeter lines

, 2017
Magnetic fields play important roles in many astrophysical processes. However, there is no universal diagnostic for the magnetic fields in the interstellar medium (ISM) and each magnetic tracer has its limitation.

Anisotropic Diffusion in Pulsar Halos: Interpreting the Asymmetric Morphology of Geminga and Monogem Halos Measured by HAWC

The Astrophysical Journal
Pulsar halos are produced by electrons and positrons diffusing in the interstellar medium around their parent pulsar wind nebulae. Recent observations by High Altitude Water Cherenkov Observatory and Large High Altitude Air Shower Observatory have ...

Magnetic Fields in the Eos Cloud: Dynamically Important Fields in the Interface between Atomic and Molecular Gas

The Astrophysical Journal
The recently discovered Eos molecular cloud is a CO-dark, low-density cloud located at a distance of approximately 94 pc from the Sun which does not appear to have formed stars at any point in its history.

Magnetic Field of a Ring-like Molecular Cloud

The Astronomical Journal
We present a detailed study of the magnetic field structure in the G111 molecular cloud, a ring-like filamentary cloud within the NGC 7538 region. Our analysis combines multiwavelength polarization data and molecular-line observations to investigate the ...

Kinetic theory of interstellar density and magnetic field fluctuations. Relations between interstellar density and magnetic field fluctuations

, 2002
Using linear kinetic plasma theory the relation between electron density and magnetic field fluctuations for low-frequency plasma waves for Maxwellian background distribution functions of arbitrary temperatures in an uniform magnetic field is derived.
