Filter Results
  • Galilean moons & Jupiter positions

    Observational results are presented for Jupiter and its Galilean moons from the Normal Astrograph at Pulkovo Observatory in 2013-2015. The following data are obtained: 154...
  • Gamma-ray emitting jetted AGN

    We considered the fourth catalog of gamma-ray point sources produced by the Fermi Large Area Telescope (LAT) and selected only jetted active galactic nuclei (AGN) or sources...
  • Observations of the Galilean moons

    Results of observations of the Galilean moons of Jupiter were carried out at the Normal Astrograph of the Pulkovo Observatory in 2018. We obtained 452 positions of the Galilean...
  • Galactic plane VERA survey

    In order to search for new VLBI sources in the galactic plane that can be used as phase reference sources in differential VLBI, we conducted 22GHz observations of radio sources...
  • IRAS/SiO sources in the Galactic bulge

    Near-infrared imaging observations of IRAS sources with SiO masers were made with the 2.3-m telescope of the Australian National University at Siding Spring Observatory,...
  • VSOP 5 GHz AGN Survey

    The VSOP mission is a Japanese-led project to image radio sources with sub-milliarcsec resolution by correlating the signal from the orbiting 8-m telescope, HALCA, with a global...
  • IRAS/SiO sources toward Galactic Bulge

    Near-infrared photometric observations in the J-, H-, and K-bands have been made for 86 IRAS sources toward the inner Galactic bulge (|l|<3{deg} and |b|<3{deg}). SiO maser...
  • BVRi'z'JHKs photometry of ERO objects

    We studied the evolution of elliptical galaxies at z>~1 using a sample of 247 Extremely Red Objects (EROs) with R-Ks>3.35 (AB) and Ks<=22.1 (AB) constructed from...
  • Water maser survey of late-type stars

    This paper presents new results of a water maser survey of late-type stellar objects at 22.235GHz with the Kashima 34-m radio telescope. We have detected 179 out of 643 observed...
  • SSA 22 field NIR imaging

    Deep narrow- and broad-band near-infrared imaging observations of the central 2'x2' region of the SSA 22 field were made with the near-infrared camera (CISCO) attached to the...
  • SiO maser survey toward inner Galactic disk

    We present the results of an SiO maser survey for color-selected IRAS sources in the area 40{deg}<l<70{deg} and |b|<10{deg} in the SiO J=1-0, v=1 and 2 transitions...
  • Geneva-Copenhagen Survey of Solar neighbourhood

    (no description available) Cone search capability for table V/117A/newcat (Main catalogue recalibrated data (2007))
  • Catalog of Star-Forming Regions in the Galaxy

    This Catalog of Star-Forming Regions in the Galaxy contains coordinates and fluxes of young objects in the radio and infrared, as well as data on the radial velocities of...
  • SiO maser survey of cold IRAS sources

    We present the results of observations of cold IRAS sources in the Galactic disk area, -10{deg}<l<100{deg} and |b|<5{deg}, in the SiO J=1-0, v=1 and 2 maser lines. SiO...
  • SKY2000 Catalog, Version 4

    The SKYMAP Star Catalog System consists of a Master Catalog stellar database and a collection of utility software designed to create and maintain the database and to generate...
  • Catalog of Cataclysmic Variables

    The Catalog and Atlas of Cataclysmic Variables (Edition 1: Downes & Shara; Edition 2: Downes, Webbink, & Shara) has been a valuable source of information for the...
  • Galactic O star catalog

    We have produced a catalog of 378 Galactic O stars with accurate spectral classifications that is complete for V<8 but includes many fainter stars. The catalog provides...
  • MSX6C Infrared Point Source Catalog

    Version 2.3 of the Midcourse Space Experiment (MSX) Point Source Catalog (PSC), which supersedes the version (1.2) that was released in 1999 (Cat. V/107), contains over 100,000...
  • Catalogue of field contact binary stars

    The catalogue of 361 galactic contact binaries is presented. Enlisted contact binaries are divided into five groups according to the type and quality of the available...
  • Catalog of Cataclysmic Variables

    The Catalog and Atlas of Cataclysmic Variables (Edition 1: Downes & Shara; Edition 2: Downes, Webbink, & Shara) has been a valuable source of information for the...
