Self-Generated Magnetic Fields in Galactic Cooling Flows [PDF]

open access: yes, 1997
Interstellar magnetic fields in elliptical galaxies are assumed to have their origin in stellar fields that accompany normal mass loss from an evolving population of old stars.

Cosmic-ray driven dynamo in galaxies [PDF]

open access: yes, 2011
We present recent developments of global galactic-scale numerical models of the Cosmic Ray (CR) driven dynamo, which was originally proposed by Parker (1992).

On the 3D Curvature and Dynamics of the Musca Filament

open access: yesThe Astrophysical Journal, 2023
Filaments are ubiquitous in the interstellar medium, yet their formation and evolution remain the topic of intense debate. In order to obtain a more comprehensive view of the 3D morphology and evolution of the Musca filament, we model the C ^18 O(2-1 ...

The Interstellar Environment of our Galaxy [PDF]

open access: yes, 2001
We review the current knowledge and understanding of the interstellar medium of our galaxy. We first present each of the three basic constituents - ordinary matter, cosmic rays, and magnetic fields - of the interstellar medium, laying emphasis on their ...

Polarisation of submillimetre lines from interstellar medium [PDF]

open access: yes, 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.

TRIANGULATION OF THE INTERSTELLAR MAGNETIC FIELD [PDF]

open access: yesThe Astrophysical Journal, 2015
Determining the direction of the local interstellar magnetic field (LISMF) is important for understanding the heliosphere's global structure, the properties of the interstellar medium, and the propagation of cosmic rays in the local galactic medium. Measurements of interstellar neutral atoms by Ulysses for He and by SOHO/SWAN for H provided some of the

The Galactic distribution of magnetic fields in molecular clouds and HII regions [PDF]

open access: yes, 2006
{Magnetic fields exist on all scales in our Galaxy. There is a controversy about whether the magnetic fields in molecular clouds are preserved from the permeated magnetic fields in the interstellar medium (ISM) during cloud formation. We investigate this

Turbulent amplification of interstellar magnetic fields [PDF]

open access: yesSymposium - International Astronomical Union, 1991
We show that the radiative cooling properties of the interstellar gas lead naturally to a scaling law for the magnetic field of the form B ∝ n1/2, if the magnetic field is amplified by a vigorous injection of turbulent energy due to expanding HII regions, stellar winds, supernova explosions, stellar jets, etc.

Interstellar Polarization Survey. II. General Interstellar Medium

open access: yesThe Astronomical Journal, 2023
Magnetic fields permeate the entire Galaxy and are essential to, for example, the regulation of several stages of the star formation process and cosmic-ray transportation.

Biermann Mechanism in Primordial Supernova Remnant and Seed Fields

open access: yes, 2006
We have studied the generation of magnetic fields by the Biermann mechanism in the pair-instability supernovae explosions of the first stars. The Biermann mechanism produces magnetic fields in the shocked region between the bubble and interstellar medium
