Interstellar Dust Scattering Properties

, 2003
Studies of dust scattering properties in astrophysical objects with Milky Way interstellar dust are reviewed. Such objects are reflection nebulae, dark clouds, and the Diffuse Galactic Light (DGL). To ensure their basic quality, studies had to satisfy four basic criteria to be included in this review.

Polarization‐Selective Metamaterial Absorber for Long‐ to Very Long‐Wavelength Infrared Broadband

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Broadband and polarization‐selective metamaterial absorbers for long‐ to very long‐wavelength infrared light with high extinction ratios are designed and demonstrated, which provide a new method for broadband polarization‐selective absorbers. ABSTRACT Metamaterial absorbers have received extensive research interest and sustained attention due to their ...

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments

Helvetica Chimica Acta, Volume 109, Issue 5, May 2026.
ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Investigation of Interstellar Scintillation of the Millisecond Pulsar B1937+21 with the FAST

The Astrophysical Journal
Pulsar scintillation serves as a valuable tool for investigating interstellar scattering screens and their properties. In this paper, we report on multiepoch interstellar scintillation from the millisecond pulsar B1937+21 (J1939+2134) using Five-hundred ...

Scattering by Interstellar Dust Grains. I. Optical and Ultraviolet [PDF]

The Astrophysical Journal, 2003
Scattering and absorption properties at optical and ultraviolet wavelengths are calculated for an interstellar dust model consisting of carbonaceous grains and amorphous silicate grains. Polarization as a function of scattering angle is calculated for selected wavelengths from the IR to the vacuum UV.

The May 2024 Superstorm Coronal Mass Ejections as Observed by the Psyche Gamma‐Ray and Neutron Spectrometer

Space Weather, Volume 24, Issue 5, May 2026.
Abstract We report new measurements of high‐energy protons ejected by the sun during the May 2024 Ganon superstorm. Our observations were made by the Neutron Spectrometer (NS) on the Psyche spacecraft, which was located at a solar distance of approximately 2 AU and a Sun‐Earth‐Probe separation angle of 75°.

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 ...

The nature of interstellar dust as revealed by light scattering

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.
