我们提出了一份硬x射线源的目录，这些硬x射线源是用雨燕天文台上的突发警报望远镜（BAT）编码掩模成像仪在前105个月的观测中探测到的。为期105个月的Swift-BAT巡天是一项均匀的硬x射线全天巡天，灵敏度超过90%的天空，在14-195 keV波段超过50%的天空。Swift-BAT为期105个月的目录提供了1632个（422个新探测到的）硬x射线源，在14-195 keV波段高于显著性水平。加上先前已知的硬x射线源，34%（144/422）的新探测被确定为附近星系（）中的Seyfert活动星系核（agn）。其余大部分已确定的源是x射线双星（7%,31）和耀变体/BL Lac天体（10%,43）。作为新版Swift-BAT目录的一部分，我们在在线期刊和Swift-BAT 105个月的网站上发布了每个对象的8通道光谱和每月采样光曲线。
We present a catalog of hard X-ray sources detected in the first 105 months of observations with the Burst Alert Telescope (BAT) coded-mask imager on board the Swift observatory. The 105-month Swift-BAT survey is a uniform hard X-ray all-sky survey with a sensitivity of over 90% of the sky and over 50% of the sky in the 14–195 keV band. The Swift-BAT 105-month catalog provides 1632 (422 new detections) hard X-ray sources in the 14–195 keV band above the significance level. Adding to the previously known hard X-ray sources, 34% (144/422) of the new detections are identified as Seyfert active galactic nuclei (AGNs) in nearby galaxies ( ). The majority of the remaining identified sources are X-ray binaries (7%, 31) and blazars/BL Lac objects (10%, 43). As part of this new edition of the Swift-BAT catalog, we release eight-channel spectra and monthly sampled light curves for each object in the online journal and at the Swift-BAT 105-month website.
