We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency decomposition. This search is sensitive to bursts of duration much less than a second and with frequency content in the 100-1100 Hz range. It features significant improvements in the

We present high time-resolution multicolour observations of the quiescent soft X-ray transient XTE J1118+480 obtained with ULTRACAM. Superimposed on the double-humped continuum g'- and i'-band light curves are rapid flare events which typically last a few minutes. The power density spectrum of the light curves can be described by a broken power-law

We subjected 106 new high-resolution spectra of the double-lined spectroscopic close binary varepsilon Lup, obtained in a time-span of 17 days from two different observatories, to a detailed study of orbital and intrinsic variations. We derived accurate values of the orbital parameters. We refined the sidereal orbital period to 4.55970d days and

We present the results of the analysis of spectra and photometry for more than 14,000 stars which are part of the second public data release of the Sloan Digital Sky Survey. We discuss the inferred metallicities and distances, which suggest that the formation of the Galactic thick disk took place over a short period of time.

The Isaac Newton Telescope (INT) Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800-deg2 CCD survey of the northern Milky Way spanning the latitude range -5° b + 5° and reaching down to r'~= 20 (10σ). Representative observations and an assessment of point-source data from IPHAS, now underway, are presented. The data obtained
