摘要:

一个新的TeV源HESS J1641 - 463是由高能立体系统(H.E.S.S.)在银河系平面偶然发现的。在8.6个标准差的显著性水平上。HESS J1641 - 463的观测是在2004年至2011年之间进行的,在E> 1 TeV时,该源的通量水平为蟹状星云通量的1.7%。HESS J1641 - 463具有1.99 ± 0.13_stat ± 0.20_sys的相当硬的光子指数。HESS J1641 - 463在位置上与射电超新星遗迹SNR G338.5 + 0.1重合,但在钱德拉对该地区的档案观测中没有发现明确的X射线对应物。不同的可能VHE生产方案将在这方面的贡献进行讨论。

英文摘要:

A new TeV source, HESS J1641-463, has been serendipitously discovered in the Galactic plane by the High Energy Stereoscopic System (H.E.S.S.) at a significance level of 8.6 standard deviations. The observations of HESS J1641-463 were performed between 2004 and 2011 and the source has a moderate flux level of 1.7% of the Crab Nebula flux at E > 1 TeV. HESS J1641-463 has a rather hard photon index of 1.99 +- 0.13_stat +- 0.20_sys. HESS J1641-463 is positionally coincident with the radio supernova remnant SNR G338.5+0.1, but no clear X-ray counterpart has been found in archival Chandra observations of the region. Different possible VHE production scenarios will be discussed in this contribution.
