Abstract
I will present the a first look of the representative 450 micron polarization images taken with the B-fields In STar-forming Region Observations (BISTRO) survey using the POL-2 polarimeter POL-2 in front of the Sub-millimeter Common-User Bolometer Array 2 (SCUBA-2) camera on the James Clerk Maxwell Telescope (JCMT) obtained as of 2018 summer. In the talk, I present the survey’s objectives and the results from the 850-micron linear polarization images of thermal emission from dusts, as well as the 450 micron ones. Typical sensitivity of the POL-2 maps is almost one order of magnitude higher than the previous images, allowing us to detect weakly polarized emission, even e.g., in the periphery of molecular clouds and inside molecular filaments. Clearly BISTRO data stand unique in the sense that they connect spatial scales that can be imaged with the Planck satellite and ALMA. In the talk, a first comparison of the polarization properties measured by the 850 and 450 micron will be presented along with future analysis plans.
