When Magnetic Fields Sculpt the Sky: The Riegel–Crutcher Cloud in Optical Polarization

The Astrophysical Journal
Filamentary structures are ubiquitous in the interstellar medium, yet the extent to which magnetic fields influence the morphology of cold atomic gas remains an open question.

Synchrotron Polarization of Anisotropic Electron Distribution in GRB Prompt Emission

The Astrophysical Journal
In γ -ray bursts (GRBs), the electron pitch angle ( α ) is usually assumed to be isotropically distributed. However, recent numerical simulations indicate that only the high-energy electrons (with Lorentz factors γ  >  γ _iso ) are distributed ...

The magnetic field of the Radcliffe wave: Starlight polarization at the nearest approach to the Sun

Astronomy & Astrophysics
Aims. We investigate the geometry of the magnetic field toward the Radcliffe wave, a coherent part of the nearby Local Arm of 3 kpc in length recently discovered via three-dimensional dust mapping. Methods. We used archival stellar polarization in the optical and new measurements in the near-infrared to trace the magnetic field as projected on the ...

Mapping the Interstellar Magnetic Field Around the Heliosphere with Polarized Starlight

, 2018
Starlight that becomes linearly polarized by magnetically aligned dust grains provides a viable diagnostic of the interstellar magnetic field (ISMF). A survey is underway to map the local ISMF using data collected at eight observatories in both hemispheres.

B-fields and Dust in Interstellar Filaments Using Dust Polarization (BALLAD-POL). III. Grain Alignment and Disruption Mechanisms in G34.43+0.24 Using Polarization Observations from JCMT/POL-2

The Astrophysical Journal
Polarization of starlight and thermal dust emission due to aligned non-spherical grains helps us to trace magnetic field ( B -field) morphology in molecular clouds and to study grain alignment mechanisms.

B-fields and Dust in Interstellar Filaments Using Dust Polarization (BALLAD-POL). II. Testing the Radiative Torque Paradigm in Musca and OMC-1

The Astrophysical Journal
Polarization of starlight and thermal dust emission caused by aligned dust grains is a valuable tool to characterize magnetic fields ( B -fields) and constrain dust properties. However, the grain alignment physics is not fully understood.
