R[SUB]nu[/SUB]-dependent optical and near-ultraviolet extinction

The correlation of optical-near-infrared photometry for a sample of stars with well-determined ultraviolet extinction is examined. A good correlation is found; in particular, it is found that the value of total-to-selective extinction correlates…

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…

In this paper we analytically study the resonance response of cylindrical subwavelength apertures embedded in metal films at near-UV, optical, and near-IR frequencies. This analysis is concise, and allows accurate and intuitive prediction of both…

Titania is a material with structural flexibility, and as a result, readily forms both crystalline polymorphs and an amorphous structure in thin films grown near room temperature. The goal of this study is to correlate fundamental optical absorption…

The near-ultraviolet (300-360 nm, 33 300-27 800 cm-) absolute absorption cross sections for formaldehyde (CH20) have been measured as a function of temperature (223-293 K), and formaldehyde concentration in nitrogen at 500 Torr. Fourier transform…

A method is presented for obtaining the approximate values of the extinction coefficient of weakly absorbing dielectrics in the near-UV region. In the method we use only the transmittance data of a dielectric plate or film and do not need the…

Asingle-frequency autoscan laser spectrometer operating in the ultraviolet in combinationwith a collimated molecular beam has been used to measurehigh-resolution fluorescence excitation spectra of the 6V, 10V, and 13Vband systems of CS2. The Zeeman…

Template fits to observed galaxy fluxes allow calculation of K-corrections and conversions among observations of galaxies at various wavelengths. We present a method for creating model-based template sets given a set of heterogeneous photometric and…

New values for the quantum yield of silicon in the 3 to 5 eV spectral region are derived from reflectance and photoresponse measurements on oxide/p+/n/n+ photodiode structures. The new values fall between high and low estimates derived from a recent…

We present high-resolution images of the Sun in the near ultraviolet spectral range between 214 nm and 397 nm as obtained from the first science flight of the 1-m Sunrise balloon-borne solar telescope. The quiet-Sun rms intensity contrasts found in…
