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. ...

... The Observatory, the cupola of which is 480 cm wide, is equipped with a Ritchey-Cretien 500 mm f/7.5 telescope, a 200 mm f/7.5 guide telescope, and a 250 mm f/13 Baker-Schmidt, a ST4 and a ST6 CCD cameras and four computers. ... Up until now we have archived about 600 images from the first observation, and 100 from the second, thanks to the automatic telescope aiming control program written by Vairo Risoldi. ... A.Nakamura, Japan, took CCD image of NGC5775. ...

Next: Widening Access Up: annrep2003 Previous: M.D. Smith, Research Astronomer .

... We present the first results of the application of Positive Matrix Factorization (PMF) to the analysis of molecular line spectra. ... The principles of the method are discussed and some results from the analysis of -spectra from the Thumbprint Nebula are shown. ... The Positive Matrix Factorization . ... Thumbprint Nebula . ... Figure 1: a) The first 20 singular values of a matrix containing the 92 -spectra used in the analysis. b) An example of a factorization of rank one . ...

... 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. ...
