The JCMT BISTRO Survey: Evidence for Pinched Magnetic Fields in Quiescent Filaments of NGC 1333
Yasuo Doi, Kohji Tomisaka, Tetsuo Hasegawa +33
We investigate the internal 3D magnetic structure of dense interstellar filaments within NGC 1333 using polarization data at from the -fields In STar-forming R…
On planet formation around supermassive black holes and the grain disruption barriers by radiative torques
Nguyen Chau Giang, Thiem Hoang, Le Ngoc Tram +5
It has recently been suggested that planets can form by dust coagulation in the torus of active galactic nuclei (AGN) with low luminosity of $L_{\rm bol}\lesssim 10^{42} erg s^{-1}…
Erosion of Icy Interstellar Objects by Cosmic Rays and Implications for `Oumuamua
Vo Hong Minh Phan, Thiem Hoang, Abraham Loeb
We study the destruction and modification of icy interstellar objects by cosmic rays and gas collisions. Using the cosmic-ray flux measured in the local interstellar medium as well…
The JCMT BISTRO Survey: An 850/450m Polarization Study of NGC 2071IR in OrionB
A-Ran Lyo, Jongsoo Kim, Sarah Sadavoy +143
We present the results of simultaneous 450 m and 850 m polarization observations toward the massive star forming region NGC 2071IR, a target of the BISTRO (B-fields in Star-F…
Effects of grain alignment with magnetic fields on grain growth and the structure of dust aggregates
Thiem Hoang
Dust grains drift through the interstellar medium (ISM) and are aligned with the magnetic field. Here we study the effect of grain alignment and grain motion on grain growth in mol…
Effect of dust rotational disruption by radiative torques on radiation pressure feedback from massive protostars
Thiem Hoang
Radiation pressure on dust is thought to play a crucial role in the formation process of massive stars by acting against gravitational collapse onto the central protostar. However,…
SOFIA observations of 30 Doradus: I -- Far-Infrared dust polarization and implications for grain alignment and disruption by radiative torques
Le Ngoc Tram, Thiem Hoang, Enrique Lopez-Rodriguez +7
Located in the Large Magellanic cloud and mostly irradiated by a massive-star cluster R136, 30 Doradus is an ideal target to test the leading theory of the grain alignment and…
The JCMT BISTRO-2 Survey: The Magnetic Field in the Center of the Rosette Molecular Cloud
Vera Könyves, Derek Ward-Thompson, Kate Pattle +33
We present the first 850 m polarization observations in the most active star-forming site of the Rosette Molecular Cloud (RMC, 1.6 kpc) in the wall of the Rosette Nebula,…
The JCMT BISTRO Survey: The Distribution of Magnetic Field Strengths towards the OMC-1 Region
Jihye Hwang, Jongsoo Kim, Kate Pattle +34
Measurement of magnetic field strengths in a molecular cloud is essential for determining the criticality of magnetic support against gravitational collapse. In this paper, as part…
Revealing the diverse magnetic field morphologies in Taurus dense cores with sensitive sub-millimeter polarimetry
Chakali Eswaraiah, Di Li, Ray S. Furuya +142
We have obtained sensitive dust continuum polarization observations at 850 m in the B213 region of Taurus using POL-2 on SCUBA-2 at the James Clerk Maxwell Telescope (JCMT), as…
