Multiscale Synthetic observations of Polarized dust emission: On the origin of Depolarization effect from Molecular clouds to Starless cores and Constraints on Dust Physics
Nguyen Chau Giang, Thiem Hoang, Blakesley Burkhart +4
Submillimeter observations of polarized dust emission from molecular clouds to starless cores frequently report a decrease in polarization fraction (p) with increasing dust emissio…
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,…
Synthetic Modelling of Polarized Dust Emission in Intermediate-Mass YSOs: II: Effects of Radiative Torque Disruption on Dust Grains in Protostellar Jets/Outflows
Nguyen Chau Giang, V. J. M. Le Gouellec, Thiem Hoang +2
One of the potential explanations for the existence of very large grains (VLGs) in the inner envelope of low/intermediate-mass Class 0/I Young Stellar Object is the migration of VL…
