Radiative torques of irregular grains: Describing the alignment of a grain ensemble
Joonas Herranen, Alex Lazarian, Thiem Hoang
The radiative torque (RAT) mechanism is the most promising way of explaining observed polarization arising from aligned grains. We explore the efficiency of the grain alignment by…
A dynamical constraint on interstellar dust models from radiative torque disruption
Thiem Hoang
Interstellar dust is an essential component of the interstellar medium (ISM) and plays critical roles in astrophysics. Achieving an accurate model of interstellar dust is therefore…
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…
Dust Rotational Dynamics in C-shocks: Rotational Disruption of Nanoparticles by Stochastic Mechanical Torques and Spinning Dust Emission
Thiem Hoang, Le Ngoc Tram
Polycyclic aromatic hydrocarbons (PAHs) and nanoparticles are expected to play an important role in many astrophysical processes due to its dominant surface area, including gas hea…
Magnetic Properties of Dust Grains, Effect of Precession and Radiative Torque Alignment
A Lazarian, Thiem Hoang
Alignment of dust grains in astrophysical environments results in the polarization of starlight as well as the polarization of radiation emitted by dust. We demonstrate the advance…
Rotational Disruption of Dust Grains by Radiative Torques in Strong Radiation Fields
Thiem Hoang, Le Ngoc Tram, Hyeseung Lee +1
Massive stars, supernovae, and kilonovae are among the most luminous radiation sources in the universe. Observations usually show near- to mid-infrared (NIR--MIR, m) e…
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…
Spectropolarimetry of Galactic stars with anomalous extinction sightlines
Aleksandar Cikota, Thiem Hoang, Stefan Taubenberger +8
Highly reddened type Ia Supernovae (SNe Ia) with low total-to-selective visual extinction ratio values, , also show peculiar linear polarization wavelength dependencies with p…
Spinning dust emission from circumstellar disks and its role in excess microwave emission
Thiem Hoang, Lan Nguyen-Quynh, Vinh Nguyen-Anh +1
Electric dipole emission from rapidly spinning polycyclic aromatic hydrocarbons (PAHs) is widely believed as an origin of anomalous microwave emission (AME), but recently it encoun…
The State-of-Play of Anomalous Microwave Emission (AME) Research
Clive Dickinson, Y. Ali-Haïmoud, A. Barr +30
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range -60 GHz. AME was first detected in 1996 and recogni…
Spinup and Disruption of Interstellar Asteroids by Mechanical Torques, and Implications for 1I/2017 U1 (`Oumuamua)
Thiem Hoang, Abraham Loeb, A. Lazarian +1
The discovery of the first interstellar asteroid, 1I/2017 U1 (`Oumuamua), has opened a new era for research on interstellar objects. In this paper, we study the rotational dynamics…
