Evolution of the Angular Momentum of Molecular Cloud Cores in Magnetized Molecular Filaments
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian +1
The angular momentum of molecular cloud cores plays a key role in the star formation process. However, the evolution of the angular momentum of molecular cloud cores formed in magn…
Tomographic Imaging of the Sagittarius Spiral Arm's Magnetic Field Structure
Yasuo Doi, Kengo Nakamura, Koji S. Kawabata +16
The Galactic global magnetic field is thought to play a vital role in shaping Galactic structures such as spiral arms and giant molecular clouds. However, our knowledge of magnetic…
Predicting reliable H column density maps from molecular line data using machine learning
Yoshito Shimajiri, Yasutomo Kawanishi, Shinji Fujita +13
The total mass estimate of molecular clouds suffers from the uncertainty in the H-CO conversion factor, the so-called factor, which is used to convert the C…
The JCMT BISTRO Survey: Studying the Complex Magnetic Field of L43
Janik Karoly, Derek Ward-Thompson, Kate Pattle +155
We present observations of polarized dust emission at 850 m from the L43 molecular cloud which sits in the Ophiuchus cloud complex. The data were taken using SCUBA-2/POL-2 on th…
Line emission from filaments in molecular clouds
F. D. Priestley, D. Arzoumanian, A. P. Whitworth
Filamentary structures are often identified in column density maps of molecular clouds, and appear to be important for both low- and high-mass star formation. Theoretically, these…
Insights on the Sun birth environment in the context of star-cluster formation in hub-filament systems
Doris Arzoumanian, Sota Arakawa, Masato I. N. Kobayashi +7
Cylindrical molecular filaments are observed to be the main sites of Sun-like star formation, while massive stars form in dense hubs, at the junction of multiple filaments. The rol…
On the 3D Curvature and Dynamics of the Musca filament
Aidan Kaminsky, Lars Bonne, Doris Arzoumanian +1
Filaments are ubiquitous in the interstellar medium (ISM), yet their formation and evolution remains the topic of intense debate. In order to obtain a more comprehensive view of th…
First BISTRO observations of the dark cloud Taurus L1495A-B10: the role of the magnetic field in the earliest stages of low-mass star formation
Derek Ward-Thompson, Janik Karoly, Kate Pattle +155
We present BISTRO Survey 850 μm dust emission polarisation observations of the L1495A-B10 region of the Taurus molecular cloud, taken at the JCMT. We observe a roughly triangular n…
Witnessing the fragmentation of a filament into prestellar cores in Orion B/NGC 2024
Y. Shimajiri, Ph. André, N. Peretto +3
Recent Herschel observations of nearby clouds have shown that filamentary structures are ubiquitous and that most prestellar cores form in filaments. Probing the density () and…
