摘要:

冰立方合作组织宣布发现了超过大气背景的中微子通量。由于急剧下降的大气背景光谱,PeV能量的事件最有可能是外星起源。我们提出的多波长特性的六个无线电最亮的耀变体的位置与这些事件一致,使用同期的数据的TANAMI耀变体样本,包括高分辨率图像和光谱能量分布。假设X射线到γ射线的辐射来源于加速质子光生π介子,那么这些辐射源的中微子光度的综合预测值就足以解释这两个观测到的PeV事件。

英文摘要:

The IceCube Collaboration has announced the discovery of a neutrino flux in excess of the atmospheric background. Due to the steeply falling atmospheric background spectrum, events at PeV energies are most likely of extraterrestrial origin. We present the multiwavelength properties of the six radio brightest blazars positionally coincident with these events using contemporaneous data of the TANAMI blazar sample, including high-resolution images and spectral energy distributions. Assuming the X-ray to γ-ray emission originates in the photoproduction of pions by accelerated protons, the integrated predicted neutrino luminosity of these sources is large enough to explain the two detected PeV events.
