用单带强子轻子含时模型研究外光子场对Blazar光谱的影响

Studying the influence of external photon fields on blazar spectra using a one-zone hadro-leptonic time-dependent model

Michael Zacharias

摘要:

最近的中微子与耀变体的关联需要相对论质子与周围软光子场的有效相互作用。然而,在中微子的旁边产生了伽马射线光子,它们与相同的软光子场相互作用,产生电子-正电子对。这种级联的强度对各个能带的光子谱有重要的影响,并对π介子和中微子的产生了严重的限制。在本研究中,我们利用一个新开发的含时单区强子轻子程序(OneHaLe)讨论了外部热光子场(吸积盘、宽线区和尘埃环)对质子-光子相互作用的影响。我们提出了稳态的情况下,以及随时间变化的情况下,发射区域移动通过射流。在这项玩具研究的范围内,外部场可能会扰乱“通常”的双峰耀变体光谱。类似地,移动区域将穿过射流的重要部分,而不会达到先前发现的稳定状态。

英文摘要:

The recent associations of neutrinos with blazars require the efficient interaction of relativistic protons with ambient soft photon fields. However, along side the neutrinos gamma-ray photons are produced which interact with the same soft photon fields producing electron-positron pairs. The strength of this cascade has significant consequences on the photon spectrum in various energy bands and puts severe constraints on the pion and neutrino production. In this study, we discuss the influence of the external thermal photon fields (accretion disk, broad-line region, and dusty torus) on the proton-photon interactions employing a newly developed time-dependent one-zone hadro-leptonic code (OneHaLe). We present steady-state cases, as well as a time-dependent case, where the emission region moves through the jet. Within the limits of this toy study, the external fields can disrupt the ``usual'' double-humped blazar spectrum. Similarly, a moving region would cross significant portions of the jet without reaching the previously-found steady states.
