摘要

我们在4颗脉冲星的诞生区域进行了恒星质量黑洞(BH)候选者的搜索。我们分析了现有的光谱、光度和天体测量数据，分离出8个天体，它们表现出与孤立黑洞理论预测相对应的特征。我们还讨论了恒星质量黑洞的观测表现——最近发现的微透镜MOA-2011-BLG-191/OGLE-2011-BLG-0462。利用该天体的现有数据计算其本地星际介质的参数，获得该天体的吸积速率和光度，并构建其理论光谱。光谱与几种仪器的灵敏度水平的比较表明，在未来的几个观测任务中，直接探测这个黑洞的发射是可能的。

Stellar mass black hole candidates in the birthplaces of radio pulsars

We performed a search for stellar-mass black hole (BH) candidates in the birth regions of 4 pulsars. We analyzed the available spectral, photometric and astrometric data to isolate 8 objects that exhibit characteristics corresponding to theoretical predictions for isolated BHs. We also discuss the observational manifestations of a stellar mass BH - the recently discovered microlens MOA-2011-BLG-191/OGLE-2011-BLG-0462. The data available for this object are used to calculate the parameters of its local interstellar medium, obtain the accretion rate and luminosity of the object, and construct its theoretical spectrum. A comparison of the spectrum with the sensitivity levels of several instruments shows that direct detection of the emission from this BH is possible for several future observing missions.
