摘要:

受最近在甚高能(VHE)伽马射线中探测到脉冲星风星云的启发,利用H.E.S.S.获得的数据,对与高能脉冲星相关的VHE伽马射线源进行了系统的搜索。(High能量立体系统)仪器。在脉冲星PSR J1718-3825附近寻找VHE伽马射线源,发现了新的VHE伽马射线源HESS J1718-385。我们报告的结果从HESS数据分析的这个来源和可能的协会与脉冲星和其他波长。我们研究了HESS J1718-385的能谱,该能谱显示出明显的峰。这是第二次观测到来自宇宙源的VHE伽马射线光谱最大值,第一次是船帆座X脉冲星风星云。

英文摘要:

Motivated by recent detections of pulsar wind nebulae in very-high-energy (VHE) gamma rays, a systematic search for VHE gamma-ray sources associated with energetic pulsars was performed, using data obtained with the H.E.S.S. (High Energy Stereoscopic System) instrument. The search for VHE gamma-ray sources near the pulsar PSR J1718-3825 revealed the new VHE gamma-ray source HESS J1718-385. We report on the results from the HESS data analysis of this source and on possible associations with the pulsar and at other wavelengths. We investigate the energy spectrum of HESS J1718-385 that shows a clear peak. This is only the second time a VHE gamma-ray spectral maximum from a cosmic source was observed, the first being the Vela X pulsar wind nebula.
