论文摘要
在这项研究中，我们使用HST，Chandra，XMM-Newton和Swift-XRT的档案数据来探测NGC 1672中9（X1-X9）候选ULX的性质。我们的研究侧重于使用基于{\ it Chandra的Optical search sellections and Handrys searchs Searchs Search and conteralsss，侧重于确定的精确源位置，并识别以下chandra}，并识别这些chandra}和searchsss，并识别这些chandra}和search。 X2 A {D X6;在相应的误差半径内确定X1，X5和X7的两个潜在对应物，而未发现其余四个来源的光学对应物。基于光谱能分布（SED），X射线和光学时间分析，获得了有关X1和X2性质的一些证据。
In this study, we use archival data from HST, Chandra, XMM-Newton, and Swift-XRT, to probe the nature of 9 (X1-X9) candidate ULXs in NGC 1672. Our study focuses on using the precise source positions obtained via improved astrometry based on {\it Chandra} and HST observations to search for and identify optical counterparts for these ULXs.Unique optical counterparts are identified for X2 an{d X6; two potential counterparts were determined for X1, X5 and X7 within the respective error radii while no optical counterparts were found for the remaining four sources. Based on spectral energy distributions (SEDs), X-ray and optical temporal analyses, some evidences about the nature of X1 and X2 were obtained.
