Broadband measurements of aerosol extinction in the ultraviolet spectral region [PDF]
Atmospheric Measurement Techniques, 2013 Aerosols influence the Earth's radiative budget by scattering and absorbing incoming solar radiation. The optical properties of aerosols vary as a function of wavelength, but few measurements have reported the wavelength dependence of aerosol extinction ...

The Astrophysical Journal, 2023 Interstellar-dust extinction law is essential for interpreting observations. In this work, we investigate the ultraviolet (UV)–mid-infrared (IR) extinction law of the Taurus molecular cloud and its possible variations. We select 504,988 dwarf stars (4200

Au@Ag Dendritic Nanoforests for Surface-Enhanced Raman Scattering Sensing
Nanomaterials, 2021 The effects of Au cores in Ag shells in enhancing surface-enhanced Raman scattering (SERS) were evaluated with samples of various Au/Ag ratios. High-density Ag shell/Au core dendritic nanoforests (Au@Ag-DNFs) on silicon (Au@Ag-DNFs/Si) were synthesized ...

The Ultraviolet Extinction in the GALEX Bands
The Astrophysical Journal, 2018 Abstract Interstellar extinction in ultraviolet is the most severe in comparison with optical and infrared wavebands and a precise determination plays an important role in correctly recovering the ultraviolet brightness and colors of objects.

PROBING THE ROLE OF CARBON IN THE INTERSTELLAR ULTRAVIOLET EXTINCTION [PDF]
The Astrophysical Journal, 2015 We probe the role of carbon in the ultraviolet (UV) extinction by examining the relations between the amount of carbon required to be locked up in dust [C/H]_dust with the 2175 Angstrom extinction bump and the far-UV extinction rise, based on an analysis of the extinction curves along 16 Galactic sightlines for which the gas-phase carbon abundance is ...

Observations of interstellar extinction in the ultraviolet with the OAO satellite [PDF]
Symposium - International Astronomical Union, 1970 We present a preliminary analysis of a number of spectrophotometric scans of reddened and unreddened early-type stars obtained with the OAO-A2 satellite. The principal findings are: (1) all the extinction curves show a ‘bump’ at 1/λ ≈ 4.5; (2) most extinction curves show a minimum at 1/λ ≈ 5.5–6.0; (3) all the extinction curves show a rapid rise in the

Effect of Aerosol Vertical Distribution on the Modeling of Solar Radiation
Remote Sensing, 2022 Default aerosol extinction coefficient profiles are commonly used instead of measured profiles in radiative transfer modeling, increasing the uncertainties in the simulations.

Interstellar Silicon Depletion and the Ultraviolet Extinction [PDF]
The Astrophysical Journal, 2017 Abstract Spinning small silicate grains were recently invoked to account for the Galactic foreground anomalous microwave emission. These grains, if present, will absorb starlight in the far-ultraviolet (UV).

Observed Interstellar Extinction in the Ultraviolet [PDF]
International Astronomical Union Colloquium, 1965 An Observational Program to measure stellar energy distributions - in the ultraviolet between 3000 Å and 1200 Å has recently been completed. The instrumentation used was similar to that reported in reference 1. A necessary preliminary for discussion of this material is some knowledge of the extinction due to interstellar absorption.
