Dust polarized emission observations of NGC 6334; BISTRO reveals the details of the complex but organized magnetic field structure of the high-mass star-forming hub-filament network
D. Arzoumanian, R. Furuya, T. Hasegawa +145
[Abridged] Filaments and hubs have received special attention recently thanks to studies showing their role in star formation. While the column density and velocity structures of b…
Observations of magnetic fields surrounding LkH 101 taken by the BISTRO survey with JCMT-POL-2
Nguyen Bich Ngoc, Pham Ngoc Diep, Harriet Parsons +146
We report the first high spatial resolution measurement of magnetic fields surrounding LkH 101, a part of the Auriga-California molecular cloud. The observations were taken with…
JCMT POL-2 and BISTRO Survey observations of magnetic fields in the L1689 molecular cloud
Kate Pattle, Shih-Ping Lai, James Di Francesco +26
We present 850m polarization observations of the L1689 molecular cloud, part of the nearby Ophiuchus molecular cloud complex, taken with the POL-2 polarimeter on the James Clerk…
Physical properties of the ambient medium and of dense cores in the Perseus star-forming region derived from Herschel Gould Belt Survey observations
S. Pezzuto, M. Benedettini, J. Di Francesco +20
(Abridged) In this paper, we present analyses of images taken with the Herschel ESA satellite from 70mu to 500mu. We first constructed column density and dust temperature maps. Nex…
Formation of the Musca filament: Evidence for asymmetries in the accretion flow due to a cloud-cloud collision
L. Bonne, S. Bontemps, N. Schneider +11
Context. Dense molecular filaments are ubiquituous in the interstellar medium, yet their internal physical conditions and formation mechanism remain debated. Aims. We study the kin…
Compressed magnetized shells of atomic gas and the formation of the Corona Australis molecular cloud
Andrea Bracco, David Bresnahan, Pedro Palmeirim +4
We present the identification of the previously unnoticed physical association between the Corona Australis molecular cloud (CrA), traced by interstellar dust emission, and two she…
Herschel Gould Belt Survey Observations of Dense Cores in the Cepheus Flare Clouds
James Di Francesco, Jared Keown, Cassandra Fallscheer +17
We present Herschel SPIRE and PACS maps of the Cepheus Flare clouds L1157, L1172, L1228, L1241, and L1251, observed by the Herschel Gould Belt Survey (HGBS) of nearby star-forming…
The census of dense cores in the Serpens region from the Herschel Gould Belt Survey
E. Fiorellino, D. Elia, Ph. André +13
The Herschel Gould Belt survey mapped the nearby (d < 500 pc) star-forming regions to understand better how the prestellar phase influences the star formation process. Here we repo…
Unifying low and high mass star formation through density amplified hubs of filaments
M. S. N. Kumar, P. Palmeirim, D. Arzoumanian +1
Context: Star formation takes place in giant molecular clouds, resulting in mass-segregated young stellar clusters composed of Sun-like stars, brown dwarves, and massive O-type(50-…
The JCMT BISTRO Survey: Magnetic Fields Associated with a Network of Filaments in NGC 1333
Yasuo Doi, Tetsuo Hasegawa, Ray S. Furuya +135
We present new observations of the active star-formation region NGC 1333 in the Perseus molecular cloud complex from the James Clerk Maxwell Telescope B-Fields In Star-forming Regi…
The structure and characteristic scales of molecular clouds
Sami Dib, Sylvain Bontemps, Nicola Schneider +8
The structure of molecular clouds (MCs) holds important clues on the physical processes that lead to their formation and subsequent evolution. While it is well established that tur…
The accretion history of high-mass stars: An ArTéMiS pilot study of Infrared Dark Clouds
N. Peretto, A. Rigby, Ph. André +14
The mass growth of protostars is a central element to the determination of fundamental stellar population properties such as the initial mass function. Constraining the accretion h…
The role of Galactic HII regions in the formation of filaments. High-resolution submilimeter imaging of RCW 120 with ArTéMiS
A. Zavagno, Ph. André, F. Schuller +13
Massive stars and their associated ionized (HII) regions could play a key role in the formation and evolution of filaments that host star formation. However, the properties of fila…
The Herschel view of the dense core population in the Ophiuchus molecular cloud
Bilal Ladjelate, Philippe André, Vera Könyves +13
Herschel observations of nearby clouds in the Gould Belt support a paradigm for low-mass star formation, starting with the generation of molecular filaments, followed by filament f…
