摘要:

利用2010年8月至2014年4月45个月的0.7- 7.0 keV波段数据,给出了国际空间站全天空X射线图像监视器(MAXI)固态狭缝相机(SSC)的第一个源星表。在0.7- 1.85 keV(软)和1.85- 7.0 keV(硬)两个能带内寻找源,极限灵敏度分别达到3和4 mCrab,在软、硬能带分别探测到140和138个源。结合两个能带,170个源被列入MAXI/SSC目录。除两个外,其余的源都被确认为22个星系,包括活动星系核,29个星系团,21个超新星遗迹,75个X射线双星,8颗恒星,5个孤立的双星和9个未分类的天体。将我们目录中最亮端的软带通量与大约20年前进行的ROSAT调查进行比较,发现10%的编目源自ROSAT时代以来改变了通量。

英文摘要:

We present the first source catalog of the Solid-state Slit Camera (SSC) of the Monitor of All-sky X-ray Image (MAXI) mission on the International Space Station, using the 45-month data from 2010 August to 2014 April in 0.7--7.0~keV bands. Sources are searched for in two energy bands, 0.7--1.85~keV (soft) and 1.85--7.0~keV (hard), the limiting sensitivity of 3 and 4~mCrab are achieved and 140 and 138 sources are detected in the soft and hard energy bands, respectively. Combining the two energy bands, 170 sources are listed in the MAXI/SSC catalog. All but 2 sources are identified with 22 galaxies including AGNs, 29 cluster of galaxies, 21 supernova remnants, 75 X-ray binaries, 8 stars, 5 isolated pulsars, and 9 non-categorized objects. Comparing the soft-band fluxes at the brightest end in our catalog with the ROSAT survey, which was performed about 20 years ago, 10\% of the cataloged sources are found to have changed the flux since the ROSAT era.
