We present X-ray analysis of three short Chandra observations of M87. The basis of this analysis is the search for possible new ultraluminous X-ray sources (ULXs) in M87's globular clusters (GCs) and attempt to quantify possible variability within the observations. We searched Chandra ObsIDs 1808 (2000 July 30, 14 ks) Wilson & Yang, 3975 (2002 November 17, 5 ks) and 3977 (2003 February 4, 5 ks) Harris et al. and identified one previously discovered GC ULX, and two new GC ULX candidates. Analysis of the light-curves revealed no new evidence of variability in these sources for the duration of the observations.

探测 M87 球状星团以燃烧超光 X 射线源

我们介绍了对 M87 的三个短钱德拉观测的 X 射线分析。该分析的基础是在 M87 的球状星团 (GC) 中寻找可能的新超发光 X 射线源 (ULX),并尝试量化观测结果中可能的变异性。我们搜索了 Chandra ObsIDs 1808(2000 年 7 月 30 日,14 ks)Wilson & Yang、3975(2002 年 11 月 17 日,5 ks)和 3977(2003 年 2 月 4 日,5 ks)Harris 等人。并确定了一个先前发现的 GC ULX 和两个新的 GC ULX 候选者。对光曲线的分析表明,在观察期间,这些光源没有变化的新证据。
