چکیده
ABSTRACT We observed the starburst galaxy M82 in 850 µm polarized light with POL-2 polarimeter on James Clerk Maxwell Telescope (JCMT). interpret our polarization geometry as tracing a two-component magnetic field: poloidal component aligned galactic ‘superwind’, extending to height ?350 pc above and below central bar; spiral-arm-aligned, or possibly toroidal, plane of galaxy, which dominates distribution at galactocentric radii ?2 kpc. Comparison results recent High-resolution Airborne Wideband Camera Plus (HAWC+) measurements field dust entrained by superwind suggests that breaks out from galaxy.

Optical and submillimetre observations of Bok globules – tracing the magnetic field from low to high density
We present optical and submillimetre polarimetry data of the Bok globule CB3. We also present optical polarimetry and submillimetre continuum data of the Bok globule CB246. We use each set of polarimetry data to infer the magnetic field orientation in each of the clouds. The optical data can only trace the field orientation in the low density edge regions of clouds, because if the extinction is...

We present an extended analysis of the Submillimetre Common User Bolometer Array (SCUBA) observations of the Hubble Deep Field (HDF), expanding the areal coverage of the Hughes et al. study by a factor of ∼1.8 and containing at least three further sources in addition to the five in that study. We also announce the public release of the reduced data products. The map is the deepest ever made in ...
