The distribution of mean and fluctuating magnetic fields in the multiphase interstellar medium [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2017 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 ...

Advances in Space Research, 1982
Abstract For three decades, magnetic fields have been known to permeate interstellar space. Each decade focussed attention on a different problem concerning the role of magnetic fields in star formation, and developed distinct techniques for the solution of the respective problem. A historical perspective of this period is given first.

The Interstellar Magnetic Field
Annual Review of Astronomy and Astrophysics, 1976Direct measurements of the interstellar magnetic field can be made only by measuring its effects on the polarization of radiation. The important effects relevant to the interstellar field are summarized. Measurements of the local field, the field on the galactic scale, the field in clouds and the field in very dense clouds are reviewed.

1987
Methods to observe magnetic fields are considered. Next, results for external galaxies are reviewed; I conclude that most results are questionable. Next, the Galactic field is reviewed. The large-scale field decreases slowly with Galactic radius and z, and has a strength ~ 4 µG near the Sun. It is a roughly circular field, which may reverse one or more

Observations of Interstellar Magnetic Fields
2003This article describes how interstellar magnetic fields are detected, measured, and mapped, the results of such observations, and the role played by interstellar magnetic fields in the physics of the interstellar medium. A goal of the observations is the measurement of the morphology and strengths of the uniform (B u) and random (B r) components of ...

Measurement of the Interstellar Magnetic Field
Nature, 1968The discovery of linear polarization of the radio emission from the pulsating radio stars1 provides an opportunity for the first direct measurement of the average magnetic field over distances of up to 100 pc from the Sun. It has already been shown2,3 that the frequency dispersion in arrival time of the pulses can be entirely explained by a dispersion ...

Interstellar: The Galactic Magnetic Field
Publications of the Astronomical Society of Australia, 1969Over a period of one year from March 1967, the 24-inch rotatable telescope at Siding Spring Observatory was used to make polarization measurements for about 1400 stars, most of which were within 400 pc of the Sun. It was found that the E vectors of the polarization formed quite definite patterns on the sky which could only be produced if the magnetic ...

Interstellar Polarization and Magnetic Fields
1987Since the work of Davis and Greenstein, polarization of starlight is quite generally considered as one of the most spectacular manifestation of the presence of magnetic fields in the interstellar space. If polarization measurements are qualitatively able to indicate the general pattern of the magnetic fields, a quantitative analysis seems more ...

Measurement of Magnetic Fields in Interstellar Clouds
Nature, 1962A new and successful attempt to measure magnetic fields in the Milky Way using the 250-ft radio telescope at Jodrell Bank is reported. The measurements were made by observing the Zeeman splitting of the neutral hydrogen line profiles. The strongest indication of Zeeman splitting was shown by the narrow deep feature of Taurus A.

The effect of magnetic fields on interstellar clouds
Symposium - International Astronomical Union, 1967I should like to say something about the equilibrium of the gas in spiral arms and about the interaction of interstellar clouds. The polarization of the light of distant stars shows that there is a quasi-regular magnetic field inside the clouds, and the Faraday rotation indicates the same for the gas between the clouds.
