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…
Galactic Dust Polarization in Turbulent Multiphase ISM: On the Origin of the Asymmetry
Yue Hu, Bao Truong, Thiem Hoang +1
Polarized thermal emission from Galactic dust is the dominant foreground for CMB polarization measurements at high frequencies, with its statistical properties shaped by the interp…
3D B-fieLds in the InterStellar medium and Star-forming regions (3D-BLISS): I. Using Starlight Polarization in the Massive IRDC Filament G11.11-0.12
Bao Truong, Thiem Hoang, Nguyen Bich Ngoc +3
Measuring three-dimensional magnetic fields (3D B-fields) is essential to understand the formation and evolution of the interstellar medium and multi-scale star formation; however,…
Grain alignment and dust evolution physics with polarisation (GRADE-POL). I. Dust polarisation modelling for isolated starless cores
Le Ngoc Tram, Thiem Hoang, Alex Lazarian +6
The polarisation of light induced by aligned interstellar dust serves as a significant tool in investigating cosmic magnetic fields, dust properties, and poses a challenge in chara…
Probing 3D magnetic fields using starlight polarization and grain alignment theory
Bao Truong, Thiem Hoang
Polarization of starlight induced by dust grains aligned with the magnetic field (hereafter B-field) is widely used to measure the two-dimensional B-fields projected onto the plane…
Evidence of Grain Alignment by Magnetically Enhanced Radiative Torques from Multiwavelength Dust Polarization Modeling of HL Tau
Nguyen Tat Thang, Pham Ngoc Diep, Thiem Hoang +4
Atacama Large Millimeter/Submillimeter Array (ALMA) has revolutionized the field of dust polarization in protoplanetary disks across multiple wavelengths. Previous observations and…
Probing 3D magnetic fields using thermal dust polarization and grain alignment theory
Thiem Hoang, Bao Truong
Magnetic fields are ubiquitous in the universe and are thought to play an important role in various astrophysical processes. Polarization of thermal dust emission from dust grains…
Numerical modeling of thermal dust polarization from aligned grains in the envelope of evolved stars with updated POLARIS
Bao Truong, Thiem Hoang, Nguyen Chau Giang +3
Magnetic fields are thought to influence the formation and evolution of circumstellar envelopes around evolved stars. Thermal dust polarization from aligned grains is a promising t…
Effects of Barnett magnetic dipole-dipole interaction on grain growth and destruction
Thiem Hoang, Bao Truong
Rapidly spinning magnetic grains can acquire large magnetic dipole moments due to the Barnett effect. Here we study the new effect of Barnett magnetic dipole-dipole interaction on…
B-fields And dust in interstelLar fiLAments using Dust POLarization (BALLAD-POL): I. The massive filament G11.11-0.12 observed by SOFIA/HAWC+
Nguyen Bich Ngoc, Pham Ngoc Diep, Thiem Hoang +8
We report the first measurement of polarized thermal dust emission toward the entire early and massive Infrared Dark Cloud G11.110.12 taken by the polarimeter SOFIA/HAWC+ at 214…
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}…
Modeling extinction and reddening effects by circumstellar dust in the Betelgeuse envelope in the presence of radiative torque disruption
Bao Truong, Le Ngoc Tram, Thiem Hoang +9
Circumstellar dust is formed and evolved within the envelope of evolved stars, including Asymptotic Giant Branch (AGB) and Red Supergiant (RSG). The extinction of stellar light by…
