BISTRO: B-fields In STar-forming Regions Observations, an Overview

The BISTRO polarimetric survey is currently being carried out with POL-2 and SCUBA-2 on the James-Clerk-Maxwell Telescope (JCMT). It covers the Gould Belt which comprises most of the nearby star-forming regions. More regions have been added to include more massive clouds. The thermal continuum emission at $850 \mu$m from aligned dust grains is linearly polarized and allows the study of magnetic fields in dense molecular clouds which cannot be covered by optical and near-infrared polarimetry. This paper presents a brief overview of results from nine papers. Topics include the morphology of the magnetic field relative to its host filament or cloud, determination of the relative contributions of large-scale and turbulent field components and the strength of the fields in various regions.
