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... -
SKY2000 - Master Star Catalog
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... -
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,... -
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... -
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... -
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... -
Southern flat-spectrum sources
Optical identifications have been sought for 198 southern radio sources (73 in Paper I, 06h<RA(B1950)<18h and 125 in Paper II, 18h<RA(B1950)<06h) using new positions... -
Star-forming galaxies in the Coma Cluster
In a field of 1deg radius centered in the Coma cluster of galaxies, UV ({lambda}=2000 A) observations with a 40-cm balloon-borne imaging telescope (FOCA) have provided a list of... -
XMM view of NGC 6231 open cluster
We present the results of an X-ray campaign towards the young open cluster NGC 6231. The XMM-Newton observations, of a total duration of about 180 ks, reveals that NGC 6231 is... -
Astrometric Catalogue 5, LQAC-5
In addition to their great astrophysical interest, quasars represent quasi-ideal reference objects in the celestial sphere with, a priori, a lack of significant proper motion.... -
Stellar content of the ROSAT all-sky survey
We present and apply a method to identify the stellar content of the ROSAT all-sky survey (RASS). We performed a crossmatch between the RASS sources and stellar candidates... -
Optical spectroscopy of 1Jy, S4 and S5 sources
(no description available) Cone search capability for table J/A+AS/105/67/table1 (Observed radio source identifications) -
The UZC-SSRS2 group catalog
We apply a friends-of-friends algorithm to the combined Updated Zwicky Catalog (UZC, Cat. )and Southern Sky Redshift Survey (SSRS2, Cat. ) to construct a catalog of 1168 groups... -
HST photometry of globulars in M81 (NGC 3031)
We perform aperture photometry and profile fitting on 419 globular cluster (GC) candidates with m_V_<=23mag identified in Hubble Space Telescope/Advanced Camera for Surveys... -
Radial velocities in M67. I. 1278 candidate members
We present results from 13776 radial-velocity (RV) measurements of 1278 candidate members of the old (4Gyr) open cluster M67 (NGC 2682). The measurements are the results of a... -
Stellar population in {rho} Oph cloud core
This contribution reports the results of an infrared imaging survey aimed at characterizing the stellar populations associated with the three densest star-forming cores in the... -
Chandra study of Rosette star-forming complex. II.
We explore here the young stellar populations in the Rosette Molecular Cloud (RMC) region with high spatial resolution X-ray images from the Chandra X-ray Observatory, which are... -
AEGIS: demographics of X-ray and optical AGN
We develop a new diagnostic method to classify galaxies into active galactic nucleus (AGN) hosts, star-forming galaxies, and absorption-dominated galaxies by combining the... -
Star-forming regions in NGC 6822 from UV data
We characterize the star formation in the low-metallicity galaxy NGC 6822 over the past few hundred million years, using GALEX far-UV (FUV, 1344-1786{AA}) and near-UV (NUV,... -
