  • Photometry in field of RX J004404.8+411820

    We propose the first association of an optical counterpart with a luminous supersoft X-ray source in M31, RX J0044.0+4118, observed with ROSAT in July 1991. The PSPC position is...
  • RR Lyrae GCVS and TYC2 identifiers

    The Tycho-2 catalogue () provides astrometric and photometric data for the 2.5 million brightest stars in the sky. Therefore it can provide much larger samples than the...
  • Merged catalogue of reflection nebulae

    Several catalogues of reflection nebulae are merged to create a uniform catalogue of 913 objects. It contains revised coordinates, cross-identifications of nebulae and stars, as...
  • Outer Galaxy IRAS sources and 12CO emission

    We examined all of the IRAS sources within the Five College Radio Astronomy Observatory (FCRAO) Outer Galaxy Survey (OGS) region for associated ^12^CO emission (as accounted for...
  • The ISOGAL field FC-01863+00035

    A 0.35x0.29{deg} field centered at l=-18.63{deg}, b=0.35{deg} was observed during the ISOGAL survey by ISOCAM imaging at 7{mu}m and 15{mu}m. 648 objects were detected and their...
  • Runaway carbon stars of Blanco & McCarthy field 37

    We have been recently faced with the problem of cross-identifying stars recorded in historical catalogues with those extracted from recent fully digitized surveys (such as DENIS...
  • Variability in the ROSAT All-Sky Survey

    We present a systematic search for variability among the ROSAT All-Sky Survey (RASS) X-ray sources. We generated lightcurves for about 30000 X-ray point sources detected...
  • Interplanetary Scintillation Pushchino Survey

    Interplanetary scintillating (IPS) radio sources from the Pushchino Survey (PS) in the area of 0.11sr have been cross-identified with objects from the 7C and FIRST catalogues....
  • Hamburg/RASS Cat. of optical ident. V3.0

    We present the Hamburg/RASS Catalogue (HRC) of optical identifications of X-ray sources at high-galactic latitude. The HRC includes all X-ray sources from the ROSAT Bright...
  • 86GHz SiO maser survey in the Inner Galaxy

    We present a compilation and study of DENIS, 2MASS, ISOGAL, MSX and IRAS 1-25 microns photometry for a sample of 441 late-type stars in the inner Galaxy, which we previously...
  • Interplanetary Scintillation Pushchino Survey II

    We present the results of optical identification of 248 interplanetary scintillating (IPS) radio sources from the Pushchino Survey (PS) in the area of 0.11sr with the center at...
  • Precise positions of RR Lyrae Stars with Vmax>12.5

    RR Lyrae stars are of great importance for investigations of Galactic structure. However, a complete compendium of all RR-Lyraes in the solar neighbourhood with accurate...
  • X-ray properties of NGC 300. I.

    X-ray properties of NGC 300 point sources, extracted from 66ks of XMM-Newton data taken in 2000 December and 2001 January. A total of 163 sources were detected in the energy...
  • Optical identification of ROSAT-FSC sources

    The Byurakan/Hamburg/ROSAT Catalogue (BHRC) of the optical identifications of X-ray sources is presented. The BHRC includes all 2791 sources from the ROSAT-FSC () with...
  • Properties of X-ray sources in M31/M33

    We have obtained optical spectra for the 14 brightest optical counterparts of X-ray sources identified by XMM-Newton in the direction of M 31 and for 21 optical counterparts in...
  • Catalogue of Galactic high-mass X-ray binaries

    We present a new edition of the catalogue of high-mass X-ray binaries in the Galaxy. The catalogue contains source name(s), coordinates, finding chart, X-ray luminosity, system...
  • Infrared study of IRAS 14416-5937 region

    We have carried out an infrared study of the southern Galactic massive star-forming region associated with IRAS 14416-5937. This star-forming region has been mapped...
  • The HELLAS2XMM survey. VIII

    We present the results of the photometric and spectroscopic identification of 110 hard X-ray selected sources from 5 additional XMM-Newton fields, nearly doubling the original...
  • Torun catalog of post-AGB and related objects

    With the ongoing AKARI infrared sky survey, of much greater sensitivity than IRAS, a wealth of post-AGB objects may be discovered. It is thus time to organize our present...
  • Catalogue of Galactic low-mass X-ray binaries

    We present a new edition of the catalogue of the low-mass X-ray binaries in the Galaxy and the Magellanic Clouds. The catalogue contains source name(s), coordinates, finding...
