论文摘要

检测到的高能脉冲星人群的数量正在增长,因此,具有敏捷且具有物理相关的代码来始终如一地分析它很重要。在这里,我们通过包括更好的粒子注入来更新现有的同步性呈辐射模型,尤其是在较大的螺距角粒子主导光谱的情况下,并实施快速准确的最小化技术。后者可以大大提高计算成本,以测试模型增强功能并将模型应用于较大的PULSAR种群。我们成功地使用X射线和$γ$ -Ray数据的脉冲星样品。我们的结果表明,对于每个发射粒子,其轨迹的空间范围很大,并且产生大多数检测到的X射线辐射是光缸的一小部分。我们还通过这种新方法确认,对于检测到的大多数伽马射线脉冲星,同步辐射不可忽略不计。此外,在获得结果的情况下,我们认为J0357+3205和J2055+2539是MEV-Pulsar候选者,建议在此能量频段中进行详尽的观察。

The detected high-energy pulsars' population is growing in number, and thus, having agile and physically relevant codes to analyze it consistently is important. Here, we update our existing synchro-curvature radiation model by including a better treatment of the particle injection, particularly where the large pitch angle particles dominate the spectra, and by implementing a fast and accurate minimization technique. The latter allows a large improvement in computational cost, needed to test model enhancements and to apply the model to a larger pulsar population. We successfully fit the sample of pulsars with X-ray and $γ$-ray data. Our results indicate that, for every emitting particle, the spatial extent of their trajectory where the pitch angle is large and most of the detected X-ray radiation is produced is a small fraction of the light cylinder. We also confirm with this new approach that synchrotron radiation is not negligible for most of the gamma-ray pulsars detected. In addition, with the results obtained, we argue that J0357+3205 and J2055+2539 are MeV-pulsar candidates and are suggested for exhaustive observations in this energy band.
