摘要:

H.E.S.S.实验已经报道了从著名的射电星系Cen A中探测到非常高能量(VHE:E>100 GeV)的伽马射线发射。根据这一发现,我们改进了以前的多斑点同步自康普顿(SSC)模型应用于多波长发射从这个源使用新的H.E.S.S.数据Lenain等人的论文中提出的对Cen A的VHE γ射线发射水平的预测与最近的数据非常吻合。进一步的VHE观测Cen A可能会发现变异性,这将使我们的内部喷流模型更加舒适。下一代成像大气切伦科夫望远镜将有助于揭示在Cen A复杂结构中可能存在的VHE发射源。

英文摘要:

The H.E.S.S. experiment has reported the detection of very high energy (VHE: E>100 GeV) gamma-ray emission from the well-known radio-galaxy Cen A. Following this discovery, we refine the previous multi-blob synchrotron self-Compton (SSC) model applied to the multi-wavelength emission from this source using the new H.E.S.S. data. The prediction of the VHE gamma-ray level of emission for Cen A presented in Lenain et al. paper agrees very well in the view of this recent data. Further VHE observations of Cen A might detect variability, which would comfort our inner jet modeling. The next generation of imaging atmospheric Cherenkov telescopes, will help to reveal possible multiple sources of VHE emission in the complex structure of Cen A.
