Systematic Underestimation of Polarization Angle Dispersion and Its Consequences for Magnetic Field Strength Estimates in Star-forming Regions

The Astrophysical Journal
Polarised dust emission observations are a valuable tool to infer the structure of the magnetic field, and the dispersion of polarization position angles may be used to estimate magnetic field strengths. A natural consequence of magnetodynamic turbulence

Magnetic fields around evolved stars [PDF]

, 2018
There has long been evidence of magnetic fields in the extended envelopes of asymptotic giant branch (AGB) and red supergiant (RSG) stars. These stars are important contributors to the enrichment of the interstellar medium by dust and heavy elements ...

BISTRO Survey: Gravity-dominated and Magnetically Regulated Star Formation in M17 SW

The Astrophysical Journal
We present high-resolution magnetic field maps of the M17 SW molecular cloud using JCMT 850 μ m dust polarization at scale of 14″. The magnetic field exhibits a distinct arc-like structure that encircles three dense clumps (C1, C2, and C3).

Heliosphere in a strong interstellar magnetic field

Journal of Physics: Conference Series, 2017
We present results of MHD simulations of the global structure of the heliosphere for a wide range of the interstellar magnetic field (ISMF) strengths (2-20 µG). For a strong interstellar field, the plasma flow in and around the heliosphere as well as the magnetic field draped over the heliopause have a simple structure, reminiscent of (though not ...

On the vertigo due to static magnetic fields. [PDF]

, 2013
Vertigo is sometimes experienced in and around MRI scanners. Mechanisms involving stimulation of the vestibular system by movement in magnetic fields or magnetic field spatial gradients have been proposed.

Evidence of Gradients of Density and Magnetic Field in the Remnant of Tycho’s Supernova

The Astrophysical Journal
By using surface brightness maps of Tycho’s supernova remnant (SNR) in radio and X-rays, along with the properties of thermal and synchrotron emission, we have derived the postshock density and magnetic field (MF) strength distributions over the ...

Interstellar Filament Detection and Characterization: Methods and Implications for Studies of the Magnetized Interstellar Medium

Galaxies
Filamentary structures are ubiquitous in the interstellar medium and play a key role in the evolution of molecular clouds and star formation. Their morphology and relative orientation with respect to magnetic fields have been widely used as a diagnostic ...
