  • R magnitude of cluster of galaxies

    We present and discuss optical measurements of the faint end of the galaxy luminosity function down to M_R_=-10 in five different local environments of varying galaxy density...
  • Observations of the distant Kuiper belt

    We present the results of a wide-field survey using the 1.2m Samuel Oschin Telescope at Palomar Observatory. This survey was designed to find the most distant members of the...
  • Chandra X-ray sources in LALA Cetus field

    The 174ks Chandra Advanced CCD Imaging Spectrometer exposure of the Large Area Lyman Alpha Survey (LALA) Cetus field is the second of the two deep Chandra images on LALA fields....
  • SN Ia properties using bolometric light curves

    We present bolometric light curves constructed from multiwavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group,...
  • DA white dwarfs in 2dF QSO Redshift Survey

    We report the spectroscopic identification of close to 1000 hydrogen-rich (DA) white dwarfs discovered in the course of the Anglo-Australian 2dF QSO Redshift Survey (2QZ, Cat....
  • New periodic variables

    Two selection statistics are used to extract new candidate periodic variables from the epoch photometry of the Hipparcos catalogue. The primary selection criterion is a...
  • Distances of white dwarf stars

    The most recent version of the Catalog of Spectroscopically Identified White Dwarfs lists 2249 white dwarf stars. Among these stars are 109 white dwarfs that have either...
  • V light curves of DI UMa

    We report an analysis of photometric behaviour of DI UMa, an extremely active dwarf nova. The observational campaign (completed in 2007) covers five superoutbursts and four...
