JCMT BISTRO survey: Magnetic Fields within the Hub-Filament Structure in IC 5146
Jia-Wei Wang, Shih-Ping Lai, Chakali Eswaraiah +130
We present the 850 m polarization observations toward the IC5146 filamentary cloud taken using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and its associated polar…
Does HL Tau Disk Polarization in ALMA Band 3 Come from Radiatively Aligned Grains?
Haifeng Yang, Zhi-Yun Li, Ian W. Stephens +2
Disk polarization in (sub)millimeter dust continuum is a rapidly growing field in the ALMA era. It opens up the exciting possibility of detecting and characterizing magnetic fields…
Two Different Grain Size Distributions within the Protoplanetary Disk around HD 142527 Revealed by ALMA Polarization Observation
Satoshi Ohashi, Akimasa Kataoka, Hiroshi Nagai +7
The origin of polarized emission from protoplanetary disks is uncertain. Three mechanisms have been proposed for such polarized emission: grain alignment with magnetic fields, grai…
Magnetic fields towards Ophiuchus-B derived from SCUBA-2 polarization measurements
Archana Soam, Kate Pattle, Derek Ward-Thompson +121
We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its…
A First Look at BISTRO Observations of The Oph-A core
Jungmi Kwon, Yasuo Doi, Motohide Tamura +119
We present 850 m imaging polarimetry data of the Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2), as part of our…
ALMA observations of polarization from dust scattering in the IM Lup protoplanetary disk
Charles L. H. Hull, Haifeng Yang, Zhi-Yun Li +9
We present 870 m ALMA observations of polarized dust emission toward the Class II protoplanetary disk IM Lup. We find that the orientation of the polarized emission is along the…
