The data presented here concerns 39 clusters of southern hemisphere and 13 clusters of northern hemisphere. (4 data files).

We present high time-resolution multicolour observations of the quiescent soft X-ray transients V404 Cyg and XTE J1118+480 obtained with ULTRACAM. The power density spectrum (PDS) of the V404 Cyg data shows a quasi-periodic oscillation (QPO) feature at 0.78 mHz (=21.5 min), whereas the PDS of the XTE J1118+480 data shows a break. We discuss the

We have obtained visible and near-infrared reflectance spectra of asteroid (1951) Lick. According to its spectral characteristics in the visible region, this object has been classified as an A-type asteroid by Bus & Binzel (cite{bus2002b}). Here we present a mineralogical analysis of the reflectance spectrum obtained for this object. We compute

We present new broadband optical and near-infrared CCD imaging together with deep optical intermediate-resolution spectroscopy of the Hickson Compact Group 31. We analyze the morphology and colors of the stellar populations of the galaxies, as well as the kinematics, physical conditions, and chemical composition of the ionized gas in order to get a

We present the results of optical and infrared photometry of the quiescent X-ray transient V404 Cyg during the period 1992-2003.

Modern kinematic diagnostics from high-S/N spectroscopy provide useful tests on the collisionless merger hypothesis for the formation of elliptical galaxies. Bender, Saglia & Gerhard (1994) show that the skewness of the line-of-sight velocity distributions (LOSVD) has opposite sign to the rotation velocity and follows a distinct pattern. Previous N
