We investigate how the [O II] properties and the morphologies of galaxies in clusters and groups at z = 0.4-0.8 depend on projected local galaxy density, and compare with the field at similar redshifts and clusters at low z. In both nearby and distant clus ...
Aims. We present spectroscopic observations of galaxies in 15 survey fields as part of the ESO Distant Cluster Survey ( EDisCS). We determine the redshifts and velocity dispersions of the galaxy clusters located in these fields, and we test for possible su ...
We present a study of the population of bright early-type dwarf galaxies in the multiple-cluster system Abell 901/902. We use data from the STAGES survey and COMBO-17 to investigate the relation between the color and structural properties of the dwarfs and ...
Transactional memory (TM) is a promising paradigm for concurrent programming. This paper is an overview of our recent work on defining a theory of TM. We first present a correctness condition of a TM, ensured by most existing TM implementations. Then, we d ...
We present deep Hubble Space Telescope NICMOS 2 F160W band observations of the central 56 '' x 57 '' (14 pc x 14.25 pc) region around R136 in the starburst cluster 30Dor (NGC 2070) located in the Large Magellanic Cloud. Our aim is to derive the stellar ini ...
Context. Although several attempts have been made to identify solar-type members on the main sequence of the nearby open cluster Coma Berenices (Mel 111), the population of the lower main sequence is still poorly known. ...
We find restrictions on the mass and mixing angle of the dark matter sterile neutrinos using x-ray observations of Coma and Virgo galaxy clusters with XMM-Newton satellite. In the absence of clearly detectable line, we present detailed analysis of various ...
We present the first study of large-scale bars in clusters at intermediate redshifts (z = 0.4 - 0.8). We compare the properties of the bars and their host galaxies in the clusters with those of a field sample in the same redshift range. We use a sample of ...

We predict the behaviour of the abundances of ff- elements and iron in the intracluster medium (ICM) as a function of redshift in poor and rich clusters. In order to do that we calculate the detailed chemical evolution of elliptical galaxies by means of on ...
