活动星系核的光子和中微子辐射
Photon and neutrino emission from active galactic nuclei
摘要：
星系中心的超大质量黑洞非常常见。我们知道，它们会旋转、吸积、自旋下降，并喷射出高度相对论性的喷流;那些指向我们的喷流似乎都显示出一个有两个强烈凸起的光谱，一个在TeV光子范围内，一个在X射线范围内--按照第一个凸起的发射频率排序，这就构成了耀变体序列。在这里，我们希望把这个序列解释为电子和质子与磁场和辐射场在相对论性喷流中的第一个强冲击波图样上的联合相互作用。在粒子散射的两个关键假设下，这个概念预测两个基本的最大峰值频率与中心黑洞的质量成比例为$M_{BH}^{-1/2}$，有一个比率为$(m_p/m_e)^{3}$，而光度与质量本身成比例为$M_{BH}$。由于轻子的强烈损失，峰值亮度通常是相同的，但在相等附近有很大的变化。这个模型预测了超高能宇宙射线的大通量，以及大的中微子光度。
英文摘要：
Supermassive black holes in the centers of galaxies are very common. They are known to rotate, accrete, spin down and eject highly relativistic jets; those jets pointed at us all seem to show a spectrum with two strong bumps, one in the TeV photon range, and one in X-rays - ordered by the emission frequency of the first bump this constitutes the blazar sequence. Here we wish to explain this sequence as the combined interaction of electrons and protons with the magnetic field and radiation field at the first strong shockwave pattern in the relativistic jet. With two key assumptions on particle scattering, this concept predicts that the two basic maximum peak frequencies scale with the mass of the central black hole as $M_{BH}^{-1/2}$, have a ratio of $(m_p/m_e)^{3}$, and the luminosities with the mass itself $M_{BH}$. Due to strong losses of the leptons, the peak luminosities are generally the same, but with large variations around equality. This model predicts large fluxes in ultra high energy cosmic rays, and also large neutrino luminosities.
