SDSS quasar catalog, sixteenth data release (DR16Q)
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog... -
Interacting galaxies catalogue
The present edition unifies two parts of Catalogue of interacting galaxies by B.A. Vorontsov-Velyaminov (1959VV....C......0V, 1970, 1977A&AS...28....1V). It contains 852... -
Cross-Identifications in Abell and Zwicky clusters
A new identification between Abell and Zwicky clusters of galaxies and vice versa is completed. Two convenient files are generated with necessary data for comparing both... -
MSX Infrared Astrometric Catalog
The MSX Infrared Astrometric Catalog has been contructed as a tool for improving the pointing accuracy of infrared observations. The catalog contains 177,860 astrometric stars,... -
Chromospherically Active Binaries
The catalog contains 206 spectroscopic binary systems with at least one late-type component that shows Ca II H and K emission in its spectrum. These systems include the... -
Extended Hipparcos Compilation (XHIP)
The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources.... -
Catalogue of LMC stars
This catalogue is a compilation of the original data related to stars in the Large Magellanic Cloud (LMC); it concerns essentially the stars brighter than m_pg_=13.5. The list... -
Chromospherically Active Binaries. Third version
Chromospherically Active Binaries (CAB) catalogue have been revised and updated. With 203 new identifications, the number of CAB stars is increased to 409. Catalogue is... -
MEGA-H proper motion catalog
The catalogue MEGA-H is a result of a merging of star lists from the catalogue of stellar proper motions with respect to galaxies in 47 selected areas near the Main Meridional... -
Catalogue of X-ray binaries
We present a catalogue of high-mass X-ray binaries. The catalogue is an updated version of the catalogue of van Paradijs (1995, Cat. ). The new high-mass catalogue contains 130... -
Byurakan-IRAS galaxies (BIG) with SDSS spectra
The sample of Byurakan-IRAS galaxies (BIG) has been created based on optical identifications of IRAS Point Source Catalog (PSC) at high galactic latitudes. As a result, 1178... -
Flare stars in the Pleiades
A brief account is given of the problems in identifying newly discovered variable stars with already known ones. These problems are most acute in dense stellar fields, for... -
Harvard variables
Coordinates and identifications are presented for 726 Harvard Variable stars and suspected variables, discovered or studied by D. Hoffleit and announced in Harvard Bulletins... -
Dolidze S, C, and MS stars positions
In the course of other work I have obtained complete identifications for a problematic list of late-type stars by Dolidze (1975AbaOB..47....3D). The charts were used to make the... -
H-ATLAS DR3 NIR counterparts in SGP field
In this paper, we present the third data release (DR3) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We identify likely near- infrared counterparts to... -
IRAS-TEXAS cross-identifications
A procedure of sampling objects by way of cross-identification of the low-frequency radio catalogue of objects obtained with the aid of the Texas interferometer at the frequency... -
Swift Galactic Plane Survey sourcelist v3
The Swift Galactic Plane Survey team report the detection of 248 point-like X-ray sources (0.3-10keV) in observations covering the final 40% of our survey area (see also... -
Catalog of X-ray active galactic nuclei
A general catalog of active galactic nuclei (AGN) has been created from identified optical sources of X-ray data from the Hamburg-ROSAT Catalog (HRC) and the Byurakan-Hamburg... -
AGN selected from an HRC/BHRC sample. II.
This is a detailed spectral classification of 198 candidate active galactic nuclei (AGN) from a joint HRC/BHRC sample consisting of a combination of the HRC (Hamburg-ROSAT) and... -
Activity types of ROSAT/SDSS galaxies
In this study we carry out detailed spectral classification of 173 AGN candidates from the Joint HRC/BHRC sample, which is a combination of HRC (Hamburg-ROSAT Catalogue) and...
