X-ray spectral components from a broad band BeppoSAX observation of the Seyfert galaxy IC 4329A
From the spectral analysis of a broadband (0.1–200 keV) BeppoSAX observation of the Seyfert 1 galaxy IC 4329A, the main results obtained are: a) the amount of reflection, together with the intensity of the iron K line, indicate a geometry with a solid angle substantially less than 2π; b) the power law is affected by a cut off with e-folding energy about 270 keV, the fourth individual object so ...
متن کاملDetailed Structural Decomposition of Galaxy Images
We present a two-dimensional (2-D) fitting algorithm (GALFIT) designed to extract structural components from galaxy images, with emphasis on closely modeling light profiles of spatially well-resolved, nearby galaxies observed with the Hubble Space Telescope. Our algorithm improves on previous techniques in two areas, by being able to simultaneously fit a galaxy with an arbitrary number of compo...
متن کاملDecomposition of AGN host galaxy images
We describe an algorithm to decompose deep images of Active Galactic Nuclei into host galaxy and nuclear components. Currently supported are three galaxy models: A de-Vaucouleurs spheroidal, an exponential disc, and a two-component disc+bulge model. Key features of the method are: (semi-)analytic representation of a possibly spatially variable point-spread function; full two-dimensional convolu...
متن کاملAdaptive Decomposition into Mono-Components
The paper reviews some recent progress on adaptive signal decomposition into mono-components that are defined to be the signals of non-negative analytic phase derivatives.
متن کاملEvaluating links through spectral decomposition
Spectral decomposition has been rarely used to investigate complex networks. In this work we apply this concept in order to define two types of linkdirected attacks while quantifying their respective effects on the topology. Several other types of more traditional attacks are also adopted and compared. These attacks had substantially diverse effects, depending on each specific network (models a...
