JCMT BISTRO Observations: Magnetic Field Morphology of Bubbles Associated with NGC 6334
Mehrnoosh Tahani, Pierre Bastien, Ray S. Furuya +142
We study the HII regions associated with the NGC 6334 molecular cloud observed in the sub-millimeter and taken as part of the B-fields In STar-forming Region Observations (BISTRO)…
Evolution of the Angular Momentum of Molecular Cloud Cores Formed from Filament Fragmentation
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian
The angular momentum of molecular cloud cores plays an essential role in the star formation process. However, the time evolution of the angular momentum of molecular cloud cores is…
The JCMT BISTRO-2 Survey: Magnetic Fields of the Massive DR21 Filament
Tao-Chung Ching, Keping Qiu, Di Li +154
We present 850 m dust polarization observations of the massive DR21 filament from the B-fields In STar-forming Region Observations (BISTRO) survey, using the POL-2 polarimeter a…
Supervised machine learning on Galactic filaments Revealing the filamentary structure of the Galactic interstellar medium
A. Zavagno, F. -X. Dupé, S. Bensaid +11
Context. Filaments are ubiquitous in the Galaxy, and they host star formation. Detecting them in a reliable way is therefore key towards our understanding of the star formation pro…
On the typical width of Herschel filaments
Ph. André, P. Palmeirim, D. Arzoumanian
Herschel studies suggest that nearby (d < 500 pc) molecular filaments have a typical half-power width ~0.1pc, but this finding has been questioned on the ground that the measured w…
The JCMT BISTRO Survey: A Spiral Magnetic Field in a Hub-filament Structure, Monoceros R2
Jihye Hwang, Jongsoo Kim, Kate Pattle +157
We present and analyze observations of polarized dust emission at 850 m towards the central 1 pc 1 pc hub-filament structure of Monoceros R2 (Mon R2). The data are obta…
The JCMT BISTRO Survey: Multi-wavelength polarimetry of bright regions in NGC 2071 in the far-infrared/submillimetre range, with POL-2 and HAWC+
L. Fanciullo, F. Kemper, K. Pattle +31
Polarized dust emission is a key tracer in the study of interstellar medium and of star formation. The observed polarization, however, is a product of magnetic field structure, dus…
From Bubbles and Filaments to Cores and Disks: Gas Gathering and Growth of Structure Leading to the Formation of Stellar Systems
Jaime E. Pineda, Doris Arzoumanian, Philippe André +8
The study of the development of structures on multiple scales in the cold interstellar medium has experienced rapid expansion in the past decade, on both the observational and the…
B-fields in Star-Forming Region Observations (BISTRO): Magnetic Fields in the Filamentary Structures of Serpens Main
Woojin Kwon, Kate Pattle, Sarah Sadavoy +149
We present 850 m polarimetric observations toward the Serpens Main molecular cloud obtained using the POL-2 polarimeter on the James Clerk Maxwell Telescope (JCMT) as part of th…
Velocity structure of the 50 pc-long NGC 6334 filamentary cloud: Hints of multiple compressions and their impact on the cloud properties?
Doris Arzoumanian, Delphine Russeil, Annie Zavagno +8
[Abridged] The interstellar medium is observed to be organised in filamentary structures, as well as neutral (HI) and ionized (HII) bubbles. The expanding nature of these bubbles m…
Filament coalescence and hub structure in MonR2: Implications to massive star and cluster formation
M. S. N. Kumar, D. Arzoumanian, A. Men'shchikov +3
Here we study the MonR2 star forming region, which has a rich network of filaments joining in a star cluster forming hub, aiming at understanding the hub structure and to examine t…
