Ice Coverage of Dust Grains in Cold Astrophysical Environments [PDF]
Physical Review Letters, 2020 Surface processes on cosmic solids in cold astrophysical environments lead to gas-phase depletion and molecular complexity. Most astrophysical models assume that the molecular ice forms a thick multilayer substrate, not interacting with the dust surface.

Probing 3D Magnetic Fields Using Thermal Dust Polarization and Grain Alignment Theory [PDF]
The Astrophysical Journal, 2023 Magnetic fields are ubiquitous in the Universe and are thought to play an important role in various astrophysical processes. Polarization of thermal emission from dust grains aligned with the magnetic field is widely used to measure the 2D magnetic field

Laboratory Studies of Charging Properties of Dust Grains in Astrophysical/Planetary Environments
Journal of Physics: Conference Series, 2012 Dust grains immersed in ambient plasmas and radiation, are charged and coupled to the plasma through electric and magnetic fields. Dust grains in various astrophysical/planetary environments are generally charged by: (a) photoelectric emissions with ...

Modest Dust Settling in the IRAS04302+2247 Class I Protoplanetary Disk [PDF]
Astrophysical Journal, 2023 We present new Very Large Array observations, between 6.8 and 66 mm, of the edge-on Class I disk IRAS04302+2247. Observations at 6.8 mm and 9.2 mm lead to the detection of thermal emission from the disk, while shallow observations at the other ...

Coevolution of Dust and Chemistry in Galaxy Simulations with a Resolved Interstellar Medium [PDF]
Astrophysical Journal, 2023 Nearby dwarf irregular galaxies are ideal laboratories for studying the interstellar medium (ISM) at low metallicity, which is expected to be common for galaxies at very high redshift being observed by JWST. We present the first high-resolution (∼0.2 pc)

Rapid Dust Growth during Hydrodynamic Clumping due to Streaming Instability [PDF]
Astrophysical Journal, 2023 Streaming instability is considered to be one of the dominant processes in promoting planetesimal formation by the gravitational collapse of dust clumps.

Joint Modelling of Dust Scattering and Thermal Emission: The Spider Complex [PDF]
Astrophysical Journal, 2023 Observations across the electromagnetic spectrum of radiative processes involving interstellar dust—emission, absorption, and scattering—are used to constrain the parameters of dust models and more directly to aid in foreground removal of dust for ...
