The Interstellar Environment of our Galaxy [PDF]

open access: yesReviews of Modern Physics, 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 ...

Interstellar Turbulence I: Observations and Processes

open access: yesAnnual Review of Astronomy and Astrophysics, 2004
This two-part review summarizes interstellar turbulence and its implications. The first part begins with diagnostics and energy sources. Turbulence theory is considered in detail, including the basic fluid equations, solenoidal and compressible modes ...

Eyes in the sky: Interactions between AGB winds and the interstellar magnetic field [PDF]

open access: yes, 2014
We aim to examine the role of the interstellar magnetic field in shaping the extended morphologies of slow dusty winds of Asymptotic Giant-branch (AGB) stars in an effort to pin-point the origin of so-called eye shaped CSE of three carbon-rich AGB stars.

Cosmic-ray driven dynamo in the medium of irregular galaxy [PDF]

open access: yes, 2009
We investigate the cosmic ray driven dynamo in the interstellar medium of irregular galaxy. The observations (Chyzy et al. 2000, 2003) show that the magnetic field in irregular galaxies is present and its value reaches the same level as in spiral ...

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 ...

Measuring interstellar magnetic fields by radio synchrotron emission [PDF]

open access: yes, 2008
Radio synchrotron emission, its polarization and its Faraday rotation are powerful tools to study the strength and structure of interstellar magnetic fields. The total intensity traces the strength and distribution of total magnetic fields.

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).

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

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.
