Abstract:
We present a catalog of sources detected by the Mikhail Pavlinsky
ART-XC telescope onboard the SRG space observatory during the
observations of the Galactic plane region near a longitude l∼20 deg
(L20 field) in October 2019. The L20 field was observed four times in
the scanning mode, which provided a uniform coverage of the sky region
with a total area of ∼24 sq. deg. with a median sensitivity of
8*10-13erg/s/cm2 (at 50% detection completeness) in the 4-12keV
energy band. As a result, we have detected 29 X-ray sources at a
statistically significant level, 11 of which have not been detected
previously by other X-ray observatories. Preliminary estimates show
that four of them can presumably be extragalactic in nature. We also
show that the source SRGA J183220.1-103508 (CXOGSG J183220.8-103510)
is most likely a galaxy cluster containing a bright radio galaxy at
redshift z∼0.121.
Description:
The catalogue contains 29 sources detected in the 4-12 keV band.

In this study we used data from the Mikhail Pavlinsky ART-XC telescope
onboard the Spectrum--Roentgen--Gamma (SRG) observatory. The SRG
observatory was designed by the Lavochkin Association (enters into the
Roskosmos State Corporation) with the participation of the Deutsches
Zentrum fur Luft- und Raumfahrt (DLR) within the framework of the
Russian Federal Space Program on the order of the Russian Academy of
Sciences. The ART-XC team thanks the Roskosmos State Corporation, the
Russian Academy of Sciences, and the Rosatom State Corporation for
supporting the design and production of the ART-XC telescope and the
Lavochkin Association and partners for the production and work with
the spacecraft and the Navigator platform.
