SNR SN 1006的TeV发射性质

On the Nature of the TeV Emission from the SNR SN 1006

Miguel Araya, Francisco Frutos-Alfaro

摘要:

我们提出了一个简单的模型,从历史超新星遗迹SN 1006的非热辐射。我们约束同步辐射参数的模型与档案无线电和硬X射线数据。我们的稳态发射模型包括两个群体的电子,这是合理的多频图像的对象。从一组参数,预测正确的同步辐射通量,我们选择那些能够占,部分或全部,为伽马射线发射的源所看到的HESS。我们使用这个模型的结果以及费米天文台施加的最新限制,并得出结论,TeV发射不能用具有单一“软”幂律分布的高能宇宙射线产生的中性π介子衰变来解释(即,颗粒指数大于2左右)。

英文摘要:

We present a simple model for the non-thermal emission from the historical supernova remnant SN 1006. We constrain the synchrotron parameters of the model with archival radio and hard X-ray data. Our stationary emission model includes two populations of electrons, which is justified by multi-frequency images of the object. From the set of parameters that predict the correct synchrotron flux we select those which are able to account, either partly or entirely, for the gamma-ray emission of the source as seen by HESS. We use the results from this model as well as the latest constraints imposed by the Fermi observatory and conclude that the TeV emission cannot be accounted for by neutral pion decay produced by high-energy cosmic rays with a single "soft" power-law distribution (i.e., with a particle index greater than 2 or so).
