  • Extinction versus Attenuation — dust_extinction v0. 1. dev176 . . .
    Both dust absorption and scattering out of the line-of-sight are processes that are directly proportional to the amount of dust along the line-of-sight As a result, the ratio of dust extinctions at two different wavelengths does not vary with different amounts of otherwise identical dust
  • Dust in Active Galactic Nuclei - A. Li
    Since a grain absorbs and scatters light most effectively at wavelengths comparable to its size 2 a, the wavelength dependence of extinction ("extinction curve") constrains the dust size distribution
  • Three-dimensional maps of the interstellar dust extinction . . .
    Interstellar dust grains scatter and absorb background light, an effect known as extinction, which is stronger at blue wavelengths than at red wavelengths How much stronger is quantified by the parameter R (V), which depends on the dust composition and size distribution
  • Galactic Dust Reddening and Extinction - IRSA
    This service gives the Galactic dust reddening for a line of sight, returning a reddening map, the corresponding 100 micron intensity, and dust temperature, along with statistics for each The total Galactic visual extinction is estimated and, in Single Location mode, extinctions at multiple wavelengths are estimated
  • Dust Extinction and Reddening - Teach Astronomy
    Ultraviolet light is almost entirely blocked, while dust extinction is much smaller at infrared wavelengths than even for optical wavelengths This is why astronomers use infrared techniques to study star-formation regions
  • Dust Extinction, Attenuation, and Emission (Chapter 4) - Star . . .
    Correctly accounting for the effects of dust allows for more accurate studies of a galaxy's stars and gas while also enabling the study of the dust grains themselves The impact of dust on measurements of individual stars in a galaxy can be straightforwardly modeled as extinguishing the stellar light
  • The origin of the dust extinction curve in milky way-like . . .
    Generally, the extinction law represents a weighted mean of the wavelength dependence of the extinction cross-section by the dust grain size distribution in the ISM The best observational constraints of extinction curves come from nearby sources, owing to the need for well-resolved sightlines
