Abstract:
We present an updated catalog of sources detected by the Mikhail
Pavlinsky ART-XC telescope aboard the Spektrum-Roentgen-Gamma (SRG)
observatory during its all-sky survey. It is based on the data of the
first four and the partially completed fifth scans of the sky
(ARTSS1-5). The catalog comprises 1545 sources detected in the 4-12keV
energy band. The achieved sensitivity ranges between
∼4x10-12erg/s/cm-2 near the ecliptic plane and
∼7x10-13erg/s/cm-2 near the ecliptic poles, which is a ∼30-50%
improvement over the previous version of the catalog based on the
first two all-sky scans (ARTSS12). There are ∼130 objects, excluding
the expected contribution of spurious detections, that were not known
as X-ray sources before the SRG/ART- XC all-sky survey. We provide
information, partly based on our ongoing follow- up optical
spectroscopy program, on the identification and classification of the
majority of the ARTSS1-5 sources (1463), of which 173 are tentative at
the moment. The majority of the classified objects (964) are
extragalactic, a small fraction (30) are located in the Local Group of
galaxies, and 469 are Galactic. The dominant classes of objects in the
catalog are active galactic nuclei (911) and cataclysmic variables
(192).
Description:
The catalogue contains 1545 sources detected in the 4-12 keV band.
