Magnetic fields and UHECR propagation [PDF]
EPJ Web of Conferences, 2023 I review the main observational tools used to detect and measure magnetic fields in the interstellar medium of our Galaxy (considering both the Galactic disk and the Galactic halo), in the interstellar medium of external galaxies, and in the ...

Interstellar Polarization Survey. IV. Characterizing the magnetic field strength and turbulent dispersion using optical starlight polarization in the diffuse interstellar medium [PDF]
The Astronomical JournalAngular dispersion functions are typically used to estimate the fluctuations in polarization angle around the mean magnetic field orientation in dense regions, such as molecular clouds.

A Large Magnetic Hump in the VLISM Observed by Voyager 1 in 2020–2022
The Astrophysical Journal, 2023 Voyager 1 has been moving through the very local interstellar medium (VLISM) for approximately one solar cycle, from 122.58 au on 2012/DOY 238 (August 25) to 158.5 au on 2023.0. Previously, an abrupt increase (“jump”) in the magnetic field strength B and

SOFIA Observations of 30 Doradus. II. Magnetic Fields and Large-scale Gas Kinematics
The Astrophysical Journal, 2023 The heart of the Large Magellanic Cloud, 30 Doradus, is a complex region with a clear core-halo structure. Feedback from the stellar cluster R136 has been shown to be the main source of energy creating multiple parsec-scale expanding-shells in the outer ...

Magnetic Misalignment of Interstellar Dust Filaments
The Astrophysical Journal, 2023 We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields. We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in ...

Plasmoid Instability in the Multiphase Interstellar Medium
The Astrophysical Journal Letters, 2023 The processes controlling the complex clump structure, phase distribution, and magnetic field geometry that develop across a broad range of scales in the turbulent interstellar medium (ISM) remain unclear.

Three-dimensional magnetic fields of molecular clouds
Frontiers in Astronomy and Space Sciences, 2022 To investigate the role of magnetic fields in the evolution of the interstellar medium, formation and evolution of molecular clouds, and ultimately the formation of stars, their three-dimensional (3D) magnetic fields must be probed.

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 ...

Interstellar Polarization Survey. II. General Interstellar Medium
The 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.
