  • ELAIS: final band-merged catalogue

    The catalog represents the final band-merged European Large-Area ISO Survey (ELAIS) Catalogue at 6.7, 15, 90 and 175{mu}m, and the associated data at U, g', r', i', Z, J, H, K...
  • POINT-AGAPE Survey. M31 variables

    For the purposes of identifying microlensing events, the POINT-AGAPE collaboration has been monitoring the Andromeda galaxy (M31) for three seasons (1999-2001) with the Wide...
  • XMM/CFDS catalogue

    We present the X-ray source catalogues for the XMM surveys of the 3-h and 14-h (also known as the Groth Strip) Canada-France Redshift Survey fields (0.5-10keV flux range...
  • 2dFGRS: Radio galaxies properties

    The clustering properties of local, S_1.4GHz_>=1mJy, radio sources are investigated for a sample of 820 objects drawn from the joint use of the Faint Images of the Radio Sky...
  • uVI photometry of 3 LMC eclipsing binaries

    CCD differential photometry in the Stromgren u, Johnson V and Cousins I bands is presented of three hot, luminous eclipsing binary stars in the Magellanic Clouds. Observations...
  • Chromospherically active binaries

    The kinematics of 237 chromospherically active binaries (CABs) were studied. The sample is heterogeneous with different orbits and physically different components from F to M...
  • The CLASS blazar survey. III.

    We discuss the properties of the sources in the CLASS blazar survey, which aims at the selection of low radio power (P_5GHz_<10^25^W/Hz) blazars. We use Very Large Array...
  • 2dFGRS Percolation-Inferred Galaxy Group (2PIGG)

    The construction of a catalogue of galaxy groups from the Two-degree Field Galaxy Redshift Survey (2dFGRS) is described. Groups are identified by means of a friends-of-friends...
  • Radio-loud QSOs at z~4

    We obtained spectra of 60 red, star-like objects (m_E_<18.8) identified with FIRST radio sources, S_1.4GHz_>1mJy. Eight are quasi-stellar objects (QSOs) with redshift...
  • OGLE II Galactic center proper motions

    We present a proper-motion catalogue of 5080236 stars in 49 Optical Gravitational Lensing Experiment II (OGLE-II) Galactic bulge (GB) fields, covering a range of...
  • Radio and K-band obs. of Ultra-Steep sources

    A sample of 76 ultra-steep spectrum (USS) radio sources is defined from the 843-MHz Sydney University Molonglo Sky Survey (SUMSS) and 1.4-GHz NRAO VLA Sky Survey (NVSS) radio...
  • HIDEEP survey

    We have carried out an extremely long integration time (9000s/beam) 21-cm blind survey of 60deg^2^ in Centaurus using the Parkes multibeam system. We find that the noise...
  • IK photometry of faint Extremely Red Objects

    We present the results from a survey for extremely red objects (EROs) in deep, high-resolution optical images taken from the Hubble Space Telescope (HST) Medium Deep Survey. We...
  • Redshifts of damped Lyman{alpha} absorbers

    We present a study of the evolution of the column density distribution, f(N,z), and total neutral hydrogen mass in high column density quasar absorbers using candidates from a...
  • Variability of the fine-structure constant

    We have previously presented evidence for a varying fine-structure constant, {alpha}, in two independent samples of Keck/HIRES quasi-stellar object (QSO) absorption spectra....
  • Shape of CL 1358+62 galaxies

    Observations of early-type galaxies, both in the local Universe and in clusters at medium redshifts, suggest that these galaxies often contain discs or disc-like structures....
  • Shape statistics of SDSS superclusters

    We study the supercluster shape properties of the recently compiled Sloan Digital Sky Survey (SDSS) cluster catalogue using an approach based on differential geometry. We detect...
  • 100-Mpc-scale structures of radio galaxies

    We present unequivocal evidence for a huge (~80x100x100Mp^3^) superstructure at redshift z=0.27 in the three-dimensional distribution of radio galaxies from the Texas-Oxford...
  • Cooling flows in 207 clusters of galaxies

    In this paper we present an X-ray image deprojection analysis of Einstein Observatory imaging data on 207 clusters of galaxies. The resulting radial profiles for luminosity,...
  • Galaxy clusters from the APM galaxy survey

    We describe the construction of catalogues of galaxy clusters from the APM Galaxy survey using an automated algorithm based on Abell-like selection criteria. We investigate the...
