The Spectral Energy Distribution and Emission-Line properties of the NLS1 Galaxy Arakelian 564
P. Romano, S. Mathur, T. J. Turner +11
We present the intrinsic spectral energy distribution (SED) of the NLS1 Arakelian 564, constructed with contemporaneous data obtained during a multi-wavelength, multi-satellite obs…
Joint Time--Frequency Analysis: a tool for exploratory analysis and filtering of non-stationary time series
R. Vio, W. Wamsteker
It is the purpose of the paper to describe the virtues of time-frequency methods for signal processing applications, having astronomical time series in mind. Different methods are…
Reddening, Emission-Line, and Intrinsic Absorption Properties in the Narrow-Line Seyfert 1 Galaxy Akn 564
D. M. Crenshaw, S. B. Kraemer, T. J. Turner +14
We use Hubble Space Telescope UV and optical spectra of the narrow-line Seyfert 1 (NLS1) galaxy Akn 564 to investigate its internal reddening and properties of its emission-line an…
The INES System IV: The IUE Absolute Flux Scale
R. Gonzalez-Riestra, A. Cassatella, W. Wamsteker
This paper deals with the definition of the input fluxes used for the calibration of the IUE Final Archive. The method adopted consists on the determination of the shape of the det…
