Probing 3D Magnetic Fields Using Thermal Dust Polarization and Grain Alignment Theory

The Astrophysical Journal
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

Status of the Stardust ISPE and the Origin of Four Interstellar Dust Candidates [PDF]

, 2012
Some bulk properties of interstellar dust are known through infrared and X-ray observations of the interstellar medium. However, the properties of individual interstellar dust particles are largely unconstrained, so it is not known whether individual ...

The Ultraviolet Slopes of Early Universe Galaxies: The Impact of Bursty Star Formation, Dust, and Nebular Continuum Emission

The Astrophysical Journal
JWST has enabled the detection of the ultraviolet (UV) continuum of galaxies at z > 10, revealing extremely blue, potentially dust-free galaxies. However, interpreting UV spectra is complicated by the well-known degeneracy between stellar ages, dust ...

Interstellar Dust Grain Alignment [PDF]

, 2018
Dust induced polarization is an efficient probe of the interstellar magnetic field. The combination of short wavelength dichroic extinction polarimetry with far-infrared/sub-mm wave emission observations, using modern instruments, allow us to measure the

The interstellar flux gap: From dust to kilometer-scale objects

Context. Three kilometer-sized interstellar objects (ISOs) have been detected transiting the Solar System, and spacecraft have directly measured micrometer-scale interstellar dust (ISD).
