Modelling Grain Rotational Disruption by Radiative Torques and Extinction of Active Galactic Nuclei
Nguyen Chau Giang, Thiem Hoang
Extinction curves observed toward individual Active Galactic Nuclei (AGN) usually show a steep rise toward far-ultraviolet (FUV) wavelengths and can be described by the Small Magel…

Gamma-ray Burst Afterglows: Time-Varying Extinction, Polarization, and Colors due to Rotational Disruption of Dust Grains
Thiem Hoang, Nguyen Chau Giang, Le Ngoc Tram
Prompt optical emission of gamma-ray bursts (GRBs) is known to have important effects on the surrounding environment. In this paper, we study rotational disruption and alignment of…

Time-Varying Extinction, Polarization, and Colors of Type Ia Supernovae due to Rotational Disruption of Dust Grains
Nguyen Chau Giang, Thiem Hoang, Le Ngoc Tram
Photometric and polarimetric observations toward type Ia supernovae (SNe Ia) frequently report an unusually low total-to-selective extinction ratio () and small peak…
