Optical counterparts of ROSAT X-ray in 2 fields
The optical identification of large number of X-ray sources such as those from the ROSAT All-Sky Survey is challenging with conventional spectroscopic follow-up observations. We... -
XMM sources in NGC1512/1510
The galaxy NGC1512 is interacting with the smaller galaxy NGC1510 and shows a peculiar morphology, characterised by two extended arms immersed in an HI disc whose size is about... -
On the metallicity of open clusters. II.
The literature was searched for [Fe/H] estimates of individual member stars of open clusters (OCs) based on the analysis of high-resolution spectra. The lower limit for spectral... -
XMM sources in M83 (NGC5236)
We present the results obtained from the analysis of three XMM-Newton observations of M83. The aims of the paper are studying the X-ray source populations in M83 and calculating... -
XMM-Newton SSC survey of Galactic Plane
Many different classes of X-ray sources contribute to the Galactic landscape at high energies. Although the nature of the most luminous X-ray emitters is now fairly well... -
Improved astrometry bor BE74 stars
Accurate astrometry is required to reliably cross-match 20th-century catalogues against 21st-century surveys. The present work aims to provide such astrometry for the 625... -
YSOs in 9 LMC star forming regions
We introduce a new set of selection criteria for the identification of infrared bright young stellar object (YSO) candidates and apply them to nine HII regions in the Large... -
MCXC Meta-Catalogue X-ray galaxy Clusters
We present the compilation and properties of a meta-catalogue of X-ray detected clusters of galaxies, the MCXC. This very large catalogue is based on publicly available ROSAT... -
Coordinates for Arp's Baade's Window stars
Identifications and coordinates for all stars in Arp's (1965ApJ...141...43A) finding chart for Baade's Window. For each star Arp's ID is presented, as are 2MASS and OGLE IDs... -
2XMMi/SDSS DR7 cross-correlation
The Survey Science Centre of the XMM-Newton satellite released the first incremental version of the 2XMM catalogue in August 2008. Containing more than 220000 X-ray sources, the... -
SEDs in ADFS (AKARI Deep Field South)
We investigate the nature and properties of far-infrared (FIR) sources in the AKARI Deep Field South (ADF-S). We performed an extensive search for the counterparts to 1000 ADF-S... -
XMM-LSS field optical identifications
The XMM-Large Scale Structure survey field (XMM-LSS) is an extragalactic window surveyed in the X-ray with the XMM-Newton satellite. It has also been observed in the optical... -
XMM-Newton survey of the ELAIS-S1 field. II.
We present the optical identifications and a multi-band catalogue of a sample of 478 X-ray sources detected in the XMM-Newton and Chandra surveys of the central 0.6deg^2^ of the... -
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... -
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... -
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... -
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... -
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... -
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... -
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...
