B-fields And dust in interstelLar fiLAments using Dust POLarization (BALLAD-POL): IV. Grain alignment mechanisms in Cocoon Nebula (IC 5146) using polarization observations from JCMT/POL-2
Saikhom Pravash, Thiem Hoang, Archana Soam +4
The polarization of starlight and thermal dust emission from aligned non-spherical grains provides a powerful tool for tracing magnetic field morphologies and strengths in diffuse…
Supermassive black hole mass measurement in the spiral galaxy NGC 4736 Using JWST/NIRSpec stellar kinematics
Dieu D. Nguyen, Hai N. Ngo, Tinh Q. T. Le +12
We present accurate mass measurements of the central supermassive black hole (SMBH) in NGC 4736 (M 94).\ We used the ``gold-standard" stellar absorption features (CO band heads) at…
The JCMT BISTRO Survey: The Magnetic Fields of the IC 348 Star-forming Region
Youngwoo Choi, Woojin Kwon, Kate Pattle +150
We present 850 m polarization observations of the IC 348 star-forming region in the Perseus molecular cloud as part of the B-fields In STar-forming Region Observation (BISTRO) s…
Observation of high Doppler velocity wings in the nascent wind of R Doradus
D. T. Hoai, P. T. Nhung, P. Tuan-Anh +4
We study the morpho-kinematics in the nascent wind of AGB star R Doradus in the light of high Doppler velocity wings observed in the spectral lines of several species. We probe dis…
First detection of HS in a protoplanetary disk. The dense GG Tau A ring
N. T. Phuong, E. Chapillon, L. Majumdar +8
Studying molecular species in protoplanetary disks is very useful to characterize the properties of these objects, which are the site of planet formation. We attempt to constrain t…
