我们报告了从费米大面积望远镜第三源目录的992个非关联源中选择的39个γ射线源的详细数据分析。为寻找候选毫秒脉冲星（MSPs）而设定的选择标准是具有弯曲光谱和bb50银河系纬度的非变量。从我们的分析中，发现24个源是点状源，没有受到背景源或附近未知源的污染。其中三个，J1544。6 - 1125, J1625。1-0021和J1653。6-0158，这表明它们很可能是msp。J0318的光谱。1+ 0252和J2053。9+ 2922不具有与已知γ射线MSPs相似的性质，因此我们认为它们不是MSPs。还对24个源中的大多数的档案x射线数据进行了分析。其中4个源在其误差圈内发现了x射线物体，16个源没有被探测到。γ射线通量与x射线通量之比或通量上限普遍低于已知的γ射线MSPs，这表明如果γ射线源是MSPs，则没有x射线物体是它们的对应物。为了确定它们的MSP性质，需要对这些源进行深x射线或射电观测。
We report our detailed data analysis of 39 γ-ray sources selected from the 992 unassociated sources in the third Fermi Large Area Telescope Third Source Catalog. The selection criteria, which were set for finding candidate millisecond pulsars (MSPs), are non-variables with curved spectra and> 5 Galactic latitudes. From our analysis, 24 sources were found to be point-like sources not contaminated by background or nearby unknown sources. Three of them, J1544. 6–1125, J1625. 1–0021 and J1653. 6–0158, have been previously studied, indicating that they are likely MSPs. The spectra of J0318. 1+ 0252 and J2053. 9+ 2922 do not have properties similar to known γ-ray MSPs, and we thus suggest that they are not MSPs. Analysis of archival X-ray data for most of the 24 sources was also conducted. Four sources were found with X-ray objects in their error circles, and 16 with no detection. The ratios between the γ-ray fluxes and X-ray fluxes or flux upper limits are generally lower than those of known γ-ray MSPs, suggesting that if the γ-ray sources are MSPs, none of the X-ray objects are their counterparts. Deep X-ray or radio observations of these sources are needed in order to identify their MSP nature.
