摘要

摘要我们介绍了SRG空间观测站上的Mikhail Pavlinsky ART-XC望远镜在2019年10月对银河面区域附近的经度(L20场)进行观测时探测到的源的星表。以扫描模式对L20场进行了四次观测,在4-12 keV能段均匀覆盖了总面积为\({\simeq}24\text{ deg}^{2}\)的天空区域,灵敏度中值为\(8\times 10^{-13}\) erg s\({}^{-1}) cm\({}^{-2}\) (探测完整性为50\(\%\))。因此,我们在统计意义上探测到了 29 个 X 射线源,其中 11 个是其他 X 射线天文台以前没有探测到的。初步估计显示,其中 4 个可能属于河外星系。我们还发现SRGA J183220.1\(-\)103508 (CXOGSG J183220.8\(-\)103510)很可能是一个星系团,其中包含一个红移\(z\simeq 0.121\)的明亮射电星系。

SRG/ART-XC Galactic Plane Survey near Galactic Longitude \(\boldsymbol{L\simeq 20^{\circ}}\): Catalog of Sources

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 \(l\simeq 20^{\circ}\) (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 \({\simeq}24\text{ deg}^{2}\) with a median sensitivity of \(8\times 10^{-13}\) erg s\({}^{-1}\) cm\({}^{-2}\) (at 50\(\%\) detection completeness) in the 4–12 keV 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 \(z\simeq 0.121\).
