... 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 . ...

... Programme . ... Abstract: Globular clusters can probe the formation history of galaxies by providing evidence for the chemical evolution and major episodes of star formation in their host galaxies, by examining their kinematic signatures, as well as their structural parameters. ... The giant elliptical NGC 5128 (Centaurus A), at a mere 4 Mpc away, gives us the only opportunity to study in extensive detail the globular cluster system of a recent merger galaxy. ...

... This represents the first HI selected sample covering the core and the outskirts of a local cluster of galaxies. ... Optically selected samples miss a considerable number of low luminosity, low surface brightness galaxies underestimating by almost a factor 2 the number of HI rich galaxies present in the cluster volume. ... Right: The g band luminosity function for galaxies in the A1367 volume as obtained from the optically (circles) and HI (histogram) selected sample. ...

... Clustering of AGN and QSOs at z=1 . Using galaxies from the DEEP2 Redshift Survey and AGN from the AEGIS/Chandra survey and QSOs from SDSS, I present the cross-correlation function of AGN/QSOs and 'normal' galaxies at z=1. Using the known clustering of DEEP2 galaxies, this leads to an estimate of the bias and typical host dark matter halo mass of AGN/QSOs as a function of X-ray luminosity, which constrains AGN formation models. oral . ...
