Description
The BISTRO (B-fields in Star-Forming Region Observations) Survey, a JCMT Large Program mapping Galactic star-forming regions with the POL-2 polarimeter, has constructed the largest extant sample of magnetic fields in star-forming region observed at sub-arc minute resolution. I will present a range of recent results from the survey, showing the similarities and differences between magnetic fields in a wide range of star-forming environments, from isolated prestellar cores, through low-mass filaments, massive infrared-dark clouds, to the Galactic Centre. I will discuss the evolution of magnetised molecular clouds to gravitational instability, and the emerging evidence for interactions between magnetic fields and stellar feedback across size scales.
