Atomic processes for astrophysical plasmas [PDF]
, 2016 In this review we summarize the recent calculations and improvements of atomic data that we have carried out for the analysis of astrophysical spectroscopy within the Atomic Processes for Astrophysical Plasmas (APA P) network.

The Journey of Interstellar Dust
, 2007 Interstellar dust particles undergo a complex journey in space. It commences with their formation in stellar outflows or outbursts, but may end in very different ways. Their fates range from sudden "death by destruction" promptly after their formation to

We model the interstellar dust content of the reionization era with a suite of cosmological, fluid-dynamical simulations of galaxies with stellar masses ranging from ∼105 to 109 M ⊙ in the first 1.2 Gyr of the Universe.

, 2020 General theory electromagnetic wave scattering in dusty plasmas is developed. It is found that dust grains change both the electron and ion fluctuations via effective ion-dust and electron-dust absorption and scattering that can be detected by broadening

A detailed study of the reflection nebula, NGC 7023 [PDF]
, 1982 Polarisation and intensity maps in three broad wavebands are presented for the reflection nebula NGC7023. The data are used to investigate the structure, dust distribution and grain characteristics of the material surrounding the central illuminating ...

The Astrophysical JournalA 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

Resonant Instabilities in Astrophysical and Laboratory Dusty Plasmas
The interaction of dust grains with plasmas is of substantial interest in both astrophysical and laboratory contexts. Dust is ubiquitous in astrophysical environments, playing a significant role in the dynamics and chemistry of systems such as molecular ...

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2
The Astrophysical JournalDiffuse 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 ...
