B-fields In STar-forming Region Observations (BISTRO): Dual-Wavelength Constraints on Size-Dependent Grain Alignment in Star-Forming Regions
Ray S. Furuya, David Berry, Pierre Bastien +65
We compared 450 and 850 m POL-2 observations from the James Clerk Maxwell Telescope at resolution. The median absolute difference in polarization angle between bands is…
B-fields In STar-forming Region Observations (BISTRO): Technical Foundations for Quantitative 450/850 m JCMT SCUBA-2/POL-2 Polarimetry
Ray S. Furuya, David Berry, Pierre Bastien +59
We present five technical validations of SCUBA-2/POL-2 polarimetry on the James Clerk Maxwell Telescope at 450 and 850 m, using 174 archival fields in 69 molecular cloud regions…
Effects of temperature-dependent optical properties on the determination of interstellar dust masses
Lapo Fanciullo, Jonathan P. Marshall, Francisca Kemper +2
Accurate measurements of interstellar dust mass are key to answering several astrophysical questions. A common method of obtaining the mass is to fit the far-infrared thermal emiss…
Grain alignment and dust evolution physics with polarisation (GRADE-POL). II. On the physical basis of Serkowski and super-Serkowski polarisation spectra
Le Ngoc Tram, Thiem Hoang, B-G Andersson +4
Optical-to-near-infrared interstellar polarisation, induced by aligned dust grains, generally follows a convex wavelength dependence, known as the Serkowski relation. However, obse…
Large Interstellar Polarisation Survey. III. Observational constraints on the structure of grains
Ralf Siebenmorgen, Stefano Bagnulo, Lapo Fanciullo +2
Dust in the diffuse interstellar medium remains incompletely understood with regard to the structure, composition, size distribution, and alignment properties of the grains. Joint…
