چکیده
Based on the ROSAT All-Sky Survey we have conducted a large redshift survey as an ESO key programme to identify and secure redshifts for the X-ray brightest clusters found in the southern hemisphere. We present first results for a highly controlled sample for a flux limit of 3 · 10 erg s cm (0.1 2.4 keV) comprising 475 clusters (87% with redshifts). The logN-logS function of the sample shows an almost perfect Euclidian slope and a preliminary X-ray luminosity function is presented.

Here we describe our attempts to establish statistically complete samples of very high redshift galaxies by obtaining photometric redshifts of galaxies in Medium Deep Survey (MDS) fields and photometric and spectroscopic redshifts of galaxies in very deep STIS slitless spectroscopy fields. On the basis of this analysis, we have identified galaxies of redshift z = 4.92 in an MDS field and of red...

We have constructed a full-sky map of the far-infrared suitable for measuring Galactic reddening and extinction ([9]: SFD). The SFD map is based upon extensive re-analysis of data from the COBE/DIRBE and IRAS satellite missions. We demonstrate that the maps can correct for extinction problems in the APM galaxy survey. We also determine the most dust-free regions for conducting cosmic microwave ...

We report on X-ray observations of the young, energetic radio pulsar PSR J1105−6107 obtained using the Rossi X-ray Timing Explorer. Our timing analysis of Proportional Counter Array data finds no evidence for X-ray pulsations from this source. We set a new upper limit on the pulsed X-ray flux from the pulsar of 18% in the 2-10 keV band, for a duty cycle of 0.5. Our improved upper limit supports...

We present results from a search to detect radio emission at 1.4 GHz from gravitationally lensed arcs towards galaxy clusters. Using the FIRST survey observations of galaxy cluster fields, we have clearly detected 1.4 GHz emission at the location of bright arc towards the galaxy cluster Abell 370. The possibility that this emission is associated with a projected galaxy superimposed on the arc c...
