An analysis of the shapes of ultraviolet extinction curves. III - an atlas of ultraviolet extinction curves

open access: yesAstrophysical Journal, Supplement Series, 1990
The basic data needed to produce UV extinction curves for a sample of 78 stars, including spectral types, visual photometry, parameters used to produce fits to the UV extinction curves, distances to the program stars, and line-of-sight H I column densities, are presented.

Ultraviolet Extinction Properties in the Milky Way [PDF]

open access: yesAstrophysical Journal, 2004
We have assembled a homogeneous database of 417 ultraviolet (UV) extinction curves for reddened sightlines having International Ultraviolet Explorer (IUE) spectra. We have combined these with optical and 2MASS photometry allowing estimates of the ratio of total-to-selective extinction, R(V), for the entire sample. Fitzpatrick-Massa (FM) parameters have

The relationship between infrared, optical, and ultraviolet extinction

open access: yesAstrophysical Journal, 1989
The parameterized extinction data of Fitzpatrick and Massa (1986, 1988) for the ultraviolet and various sources for the optical and near-infrared are used to derive a meaningful average extinction law over the 3.5 micron to 0.125 wavelength range which is applicable to both diffuse and dense regions of the interstellar medium.

Dust Plasma Analogue for Interstellar 217.5 nm Extinction [PDF]

open access: yesSerbian Astronomical Journal, 2008
The new ultraviolet (UV) extinction measurements of carbonaceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma polymerized hydrocarbon nanoparticles were already proposed as a new astro analogue, which describe the infrared (

Label-free superior contrast with c-band ultra-violet extinction microscopy

open access: yesLight: Science & Applications, 2023
In 1934, Frits Zernike demonstrated that it is possible to exploit the sample’s refractive index to obtain superior contrast images of biological cells.

One Relation for All Wavelengths: The Far-ultraviolet to Mid-infrared Milky Way Spectroscopic R(V)-dependent Dust Extinction Relationship

open access: yesThe Astrophysical Journal, 2023
Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength-dependent variations seen in Milky Way extinction are strongly correlated with the single parameter R ( V ) = A ( V )/ E ( B − V )

Initial investigation of the wavelength dependence of optical properties measured with a new multi-pass Aerosol Extinction Differential Optical Absorption Spectrometer (AE-DOAS) [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
Atmospheric aerosols directly affect climate by scattering and absorbing radiation. The magnitude of the impact is dependent upon the wavelength of light, but is often estimated near 550 nm.
