论文摘要
多波长的观测表明,某些星爆星系显示了其中部地区的主要非热贡献。这些活跃的银河核(AGN) - 星堡复合材料具有特殊的兴趣,因为这两种现象本身都是高度能量的宇宙射线的潜在来源,以及相关的伽马射线和中微子发射。在这项工作中,开发了来自AGN Corona以及周环的稳态发射的均质,稳态的两区多通讯器模型,并开发出了周期性的Starburst区域,并随后应用于NGC 1068案例,该案例最近显示了一些高增强中性中性发射的第一指示。在这里,我们表明,如果考虑到Starburst和Agn Corona都可以很好地描述多通电工数据(包括中微子约束在内的伽马射线)的整个频谱。仅使用单个发射区还不够。
Multi-wavelength observations indicate that some starburst galaxies show a dominant non-thermal contribution from their central region. These active galactic nuclei (AGN)-starburst composites are of special interest, as both phenomena on their own are potential sources of highly-energetic cosmic rays and associated gamma-ray and neutrino emission. In this work, a homogeneous, steady-state two-zone multi-messenger model of the non-thermal emission from the AGN corona as well as the circumnuclear starburst region is developed and subsequently applied to the case of NGC 1068, which has recently shown some first indications of high-energy neutrino emission. Here, we show that the entire spectrum of multi-messenger data - from radio to gamma-rays including the neutrino constraint - can be described very well if both, starburst and AGN corona, are taken into account. Using only a single emission region is not sufficient.
