Abstract: I will review the observational picture of the various gaseous components in Centaurus A. In addition, I will discuss the relation (if any) of these components and the presence of the radio source and, in particular, the presence of the radio jet. go back .

... The continuum of the Orion Nebula's template contains the nebular contribution plus a combination of Kurucz model atmospheres to simulate the stellar contribution. The fluxes of the UV, optical and near-IR emission lines from different sources are also incorporated into the template (J.R. Walsh, private comm.) The continuum of the planetary nebula has a nebular component and a hot stellar component simulated by an 80000K black body. ...

... Comparative study of Tl-2201 single crystals with different temperatures of superconducting transition by means of specific heat method. Abstract: . The comparison studies of the specific heat of Tl-2201 single crystals with the different oxygen concentration have led to the conclusion that the doping by oxygen, resulting in lowering of T c and increasing of number of paramagnetic centers, leads to diminishing of antiferromagnetic correlations contribution to the specific heat. ...

... The Impact of HST on European Astronomy . ... These range from the study of nearby planets, the processes of star and planet formation, the stellar and interstellar components of galaxies, the discovery that most, if not all, galactic nuclei harbor a massive black hole that profoundly affects their evolution, to the realisation that the universe as a whole is undergoing acceleration as a result of a yet unknown form of dark energy . ... Formation, structure and evolution of galaxies . ...

Next: Data Analysis Applications . ... The past decade has witnessed a movement within the astronomical software community towards Open Systems . ... We present examples of user-customizable systems that can be built from existing tools, based on commonly-used infrastructure: a parameter interface library, FITS file format, Unix, and the X Windows environment. ... However, the currently available parameter file systems have serious limitations when inserted into a heterogeneous environment. ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... Iron abundance in the atmospheres of components of the binary system 41 Draconis . ... 5B Iron abundances, FeI and FeII lines equivalent widths, and microturbulence velocities were found for the components of a highly eccentric spectroscopic and interferometric binary system 41 Dra from high resolution spectra obtained close to the periastron. Weighted mean values of iron abundances in the atmospheres are lgN(Fe) = 7.66 ± 0.03 and lgN(Fe) = 7.72 ± 0.03 for the component a and b, correspondingly. ...

Authors: V.A. Marsakov , T.V. Borkova , . ... It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy. The thick disk and proto-disk subsystems are genetically associated with the Galaxy. ... It is argued that heavy-element enrichment and the collapse of the proto-galactic medium occurred mainly in the period between the formation of the proto-disk halo and thick disk subsystems. ...

... Despite the wide spread use of the terms MTF, CTF, limiting resolution, minimum resolvable target, and contrast to describe CCD image system quality, the terms are often misused and their relations are little understood. ... The modulation transfer function (MTF) is a Fourier transform of the line spread function i.e. its equivalent as an integral sum of sine waves taken over the whole range of spatial frequencies. MTF by its Fourier nature can only be used to operate on sinusoidal frequencies. ...

... We propose that the bimodal nature of the kick velocity distribu­ tion of radio pulsars is connected to the dichotomy between hadronic stars (i.e. neutron stars with no quark matter content) and quark stars. ... Here we propose a scenario in which the low­velocity part of the distribution is connected with normal (hadronic) compact stars, and high­velocity part is formed by objects with some amount of quark matter inside (hybrid or strange stars). ...
