论文摘要

高能立体系统(H.E.S.S.)天文台已经对银河平面进行了深入的调查,在此过程中,确认了大量($ \ sim $ 78)TEV $γ$ - 雷来源的存在,其中许多是未识别的。 HESS J1828-099是一个点状的(高斯立场。银河平面调查(HGP)目录。该源也是唯一的,因为它似乎与在其他波长下检测到的任何对象没有任何明显的关联。我们研究了HESS J1828-099与多波长观测数据的性质和关联。高质量X射线二进制(HMXB) - 由PULSAR XTE J1829-098和同伴Be Star组成 - 在X射线和红外乐队早些时候观察到,距离Hess J1828-099的14 $'$'$'$'$'。使用12年的$ \ textit {fermi} $ - lat $γ$ - 雷数据,我们探索了4FGL J1830.2-1005是HESS J1828-099的GEV对应物的可能性。在RXTE置信区域内,陡峭的频谱($α_{Radio} $ = -0.746 $ \ pm $ 0.284)在现有无线电频率调查的数据中检测到合理的对应物。在这封信中,我们首次使用多波长数据进行探测,无论HESS J1828-099,4FGL J1830.2-1005和HMXB系统具有共同的起源。我们的研究表明,HESS J1828-099可能是TEV高质量$γ$ ray二进制来源。

The High Energy Stereoscopic System (H.E.S.S.) observatory has carried a deep survey of the Galactic plane, in the course of which the existence of a significant number of ($\sim$ 78) TeV $γ$-ray sources was confirmed, many of which remain unidentified. HESS J1828-099 is a point-like (Gaussian stand. dev. $<$ 0.07$^{\circ}$) unidentified source among the 17 confirmed point-like sources in the H.E.S.S. Galactic Plane Survey (HGPS) catalog. This source is also unique because it does not seem to have any apparent association with any object detected at other wavelengths. We investigate the nature and association of HESS J1828-099 with multi-wavelength observational data. A high mass X-Ray binary (HMXB) - comprising of pulsar XTE J1829-098 and a companion Be star - has been observed earlier in the X-ray and infrared bands, 14$'$ away from HESS J1828-099. With 12 years of $\textit{Fermi}$-LAT $γ$-ray data, we explore the possibility of 4FGL J1830.2-1005 being the GeV counterpart of HESS J1828-099. Within the RXTE confidence region, a steep spectrum ($α_{radio}$ = - 0.746 $\pm$ 0.284), plausible counterpart is detected in data from existing radio frequency surveys. In this letter, we probe for the first time using multi-wavelength data, whether HESS J1828-099, 4FGL J1830.2-1005 and the HMXB system have a common origin. Our study indicates that HESS J1828-099 might be a TeV high mass $γ$-ray binary source.
