“…For example, Kirk, Johnstone & Di Francesco (2006) find that most submillimetre cores in the Perseus molecular cloud are fit by Bonner-Ebert spheres with temperatures between 10 and 19 K. In addition, Rumble et al (2015) calculate a mean temperature of ∼15 K for YSOs in the Serpens MWC 297 region, also consistent with observations of the W40 complex (Rumble et al 2016). These higher temperatures, particularly for L1YSO 1, could be caused by the influence of the nearby Sco-Cen OB association, although Pattle et al (2015) do not find such high temperatures in the nearby region of Ophiuchus.…”

We present 450 and 850 μm submillimeter continuum observations of the IC 5146 star-forming region taken as part of the James Clerk Maxwell Telescope Gould Belt Survey. We investigate the location of bright submillimeter (clumped) emission with the larger-scale molecular cloud through comparison with extinction maps, and find that these denser structures correlate with higher cloud column density. Ninety-six individual submillimeter clumps are identified using FellWalker,and their physical properties are examined. These clumps are found to be relatively massive, ranging from 0.5  M to 116  M with a mean mass of 8  M and a median mass of 3.7  M . A stability analysis for the clumps suggests that the majority are (thermally) Jeans stable, withWe further compare the locations of known protostars with the observed submillimeter emission, finding that younger protostars, i.e., Class 0 and I sources, are strongly correlated with submillimeter peaks and that the clumps with protostars are among the most Jeans unstable. Finally, we contrast the evolutionary conditions in the two major star-forming regions within IC 5146: the young cluster associated with the Cocoon Nebula and the more distributed star formation associated with the Northern Streamer filaments. The Cocoon Nebula appears to have converted a higher fraction of its mass into dense clumps and protostars, the clumps are more likely to be Jeans unstable, and a larger fraction of these remaining clumps contain embedded protostars. The Northern Streamer, however, has a larger number of clumps in total and a larger fraction of the known protostars are still embedded within these clumps.

“…Following on from the highly successful first-generation James Clerk Maxwell Telescope (JCMT) Legacy Surveys, including the Gould Belt Legacy Survey (e.g., Ward-Thompson et al 2007Buckle et al 2010;Graves et al 2010;Sadavoy et al 2013;Pattle et al 2015Pattle et al , 2017Rumble et al 2015;Salji et al 2015;Chen et al 2016;Kirk et al 2016;Mairs et al 2016), the JCMT is currently undertaking a series of second-generation surveys, using the latest instruments to be commissioned on the telescope. These include POL-2, an imaging polarimeter for SCUBA-2.…”

We present the first results from the B-fields In STar-forming Region Observations (BISTRO) survey, using the Sub-millimetre Common-User Bolometer Array2 camera, with its associated polarimeter (POL-2), on the James Clerk Maxwell Telescope in Hawaii. We discuss the survey's aims and objectives. We describe the rationale behind the survey, and the questions thatthe survey will aim to answer. The most important of these is the role of magnetic fields in the star formation process on the scale of individual filaments and cores in dense regions. We describe the data acquisition and reduction processes for POL-2, demonstrating both repeatability and consistency with previous data. We present a first-look analysis of the first results from the BISTRO survey in the OMC1 region. We see that the magnetic field lies approximately perpendicular to the famous "integral filament" in the densest regions of that filament. Furthermore, we see an "hourglass" magnetic field morphology extending beyond the densest region of the integral filament into the less-dense surrounding material, and discuss possible causes for this. We also discuss the more complex morphology seen along the Orion Bar region. We examine the morphology of the field along the lower-density northeastern filament. We find consistency with previous theoretical models that predict magnetic fields lying parallel to low-density, non-self-gravitating filaments, and perpendicular to higher-density, self-gravitating filaments.
