On the 3D Curvature and Dynamics of the Musca Filament
The 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 ...

Turbulent amplification of interstellar magnetic fields [PDF]
Symposium - 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 ∝ n 1/2 , if the magnetic field is amplified by a ...

THE INTERSTELLAR MAGNETIC FIELD CLOSE TO THE SUN. II. [PDF]
The Astrophysical Journal, 2012 A key indicator of the galactic environment of the Sun is provided by the magnetic field in the interstellar medium (ISM), which influences the shape of the heliosphere. The direction of the nearby interstellar magnetic field (ISMF) is determined from starlight polarized in the ISM.

Obtaining the Strength of the Magnetic Field from E- and B-Modes of Dust Polarization
The Astrophysical Journal, 2023 We perform numerical simulations of supersonic magnetohydrodynamic (MHD) turbulence and calculate Fourier power spectra of E - and B -modes arising from dust polarization. We pay close attention to the ratio of E -mode to B -mode spectra (a.k.a.

Magnetic Fields in Interstellar Masers [PDF]
Symposium - International Astronomical Union, 1990 Zeeman splitting in the spectra of molecular masers that arise in the envelopes of newly formed stars (called interstellar masers) offers a method of estimating the magnetic field in these dense regions (106–1011 cm−3). The magnetic field strengths in regions of OH and H2O masers scale as the square root of the density when compared to the density and ...

Tracing Magnetic Field in Super-Alfvénic Turbulence with Gradient Technique
The Astrophysical JournalSuper-Alfvénic turbulence is important for many astrophysical objects, particularly galaxy clusters. In this paper, we explore the accuracy of synchrotron intensity gradients and X-ray intensity gradients to map magnetic fields in super-Alfvénic ...
