The Dust Echo Emission of Fast Blue Optical Transients and Application to the Near-infrared Excess of AT 2018cow

The Astrophysical Journal
A near-infrared (NIR) excess has been discovered in the emission of the representative fast blue optical transient (FBOT) AT 2018cow. It was suggested that this NIR excess could be emitted by the dust surrounding the source and thus could provide a probe

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2

The Astrophysical Journal
Diffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

Magnetically Aligned Grains as a Ubiquitous Source of Spin-polarized Electrons and Chiral-symmetry-breaking Agents

The Astrophysical Journal
The unique biosignature of life on Earth is the homochirality of organic compounds, such as amino acids, proteins, and sugars. High-energy spin-polarized (spinup or spindown) electrons (SPEs) from the β decay of radioactive nuclei have been proposed as a

Tracing the History of Obscured Star Formation with the SIMBA Cosmological Galaxy Evolution Simulation

The Astrophysical Journal
We explore the cosmic evolution of the fraction of dust-obscured star formation predicted by the simba cosmological hydrodynamic simulations featuring an on-the-fly model for dust formation, evolution, and destruction.

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

Near-infrared [P II] and [Fe II] Emission-line Study of Supernova Remnants in the Magellanic Clouds

The Astronomical Journal
We report findings from near-infrared imaging observations of 17 young and middle-aged supernova remnants (SNRs) in the Magellanic Clouds to examine the impact of SNR shocks on dust destruction and the possible detection of supernova ejecta.
