Three-dimensional magnetic fields of molecular clouds

M Tahani - Frontiers in Astronomy and Space Sciences, 2022 - frontiersin.org
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 …

Starlight-polarization-based tomography of the magnetized ISM: PASIPHAE's line-of-sight inversion method

V Pelgrims, GV Panopoulou, K Tassis… - Astronomy & …, 2023 - aanda.org
We present the first Bayesian method for tomographic decomposition of the plane-of-sky
orientation of the magnetic field with the use of stellar polarimetry and distance. This …

On the Origin of the North Celestial Pole Loop

A Marchal, PG Martin - The Astrophysical Journal, 2023 - iopscience.iop.org
Abstract The North Celestial Pole Loop (NCPL) provides a unique laboratory for studying the
early-stage precursors of star formation. Uncovering its origin is key to understanding the …

SOFIA Observations of 30 Doradus. II. Magnetic Fields and Large-scale Gas Kinematics

L Bonne, Y Hu, E Lopez-Rodriguez… - The Astrophysical …, 2023 - iopscience.iop.org
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 …

Constraining the H2 column densities in the diffuse interstellar medium using dust extinction and HI data

R Skalidis, PF Goldsmith, PF Hopkins… - Astronomy & …, 2024 - aanda.org
Context. Carbon monoxide (CO) is a poor tracer of H 2 in the diffuse interstellar medium
(ISM), where most of the carbon is not incorporated into CO molecules, unlike the situation at …

H i filaments as potential compass needles? Comparing the magnetic field structure of the Small Magellanic Cloud to the orientation of GASKAP-H i filaments

YK Ma, NM McClure-Griffiths, SE Clark… - Monthly Notices of …, 2023 - academic.oup.com
High-spatial-resolution H i observations have led to the realization that the nearby (within
few hundreds of parsecs) Galactic atomic filamentary structures are aligned with the ambient …

CO enhancement by magnetohydrodynamic waves-Striations in the Polaris Flare

R Skalidis, K Gkimisi, K Tassis, GV Panopoulou… - Astronomy & …, 2023 - aanda.org
Context. The formation of molecular gas in interstellar clouds is a slow process, but can be
enhanced by gas compression. Magneto-hydrodynamic (MHD) waves can create …

Magnetic Field at the Galactic Centre from Multi-Wavelength Dust Polarization

MS Akshaya, T Hoang - Monthly Notices of the Royal …, 2024 - academic.oup.com
We have mapped the magnetic field (B-field) for a region of about 30 pc around the centre of
our Galaxy, which encompasses the circumnuclear disk (CND), the minispiral, and the 20 …

Polarized Light from Massive Protoclusters (POLIMAP). I. Dissecting the role of magnetic fields in the massive infrared dark cloud G28. 37+ 0.07

CY Law, JC Tan, R Skalidis, L Morgan… - The Astrophysical …, 2024 - iopscience.iop.org
Magnetic fields may play a crucial role in setting the initial conditions of massive star and

First Extragalactic Detection of Thermal Hydroxyl (OH) 18 cm Emission in M31 Reveals Abundant CO-faint Molecular Gas

MP Busch - The Astrophysical Journal, 2024 - iopscience.iop.org
The most abundant interstellar molecule, molecular hydrogen (H 2), is practically invisible in
cold molecular clouds. Astronomers typically use carbon monoxide (CO) to trace the bulk …
