论文摘要
我们提出了费米气泡（FBS）中电磁场的全局结构的模型，这使得质子的常规加速能够达到超高能量。多型磁场和环形磁场以及径向电场的变形结构类似于从活性银河核（AGN）中弹出的喷气机中存在的磁场。在银河系中心观察到的相对论颗粒的强大来源，并与旋转的超质量黑洞（SMBH）SGR A*相关联，可以使FB充满电并保持其活性很长时间。在BH上没有吸积，因此没有相对论射流并不意味着没有BH旋转能量损失。对于FB，BH损失的能量可以保持FB活动。常规的FBS结构可以通过从相对论的喷气喷气机继承而形成，该喷气可能存在于Galaxy $ 10^7 $几年前的活跃过去，也可以通过在银河系的整个生命周期中存在的星系中心附近的过程中形成。发现Fb电磁场中质子的加速符合能量$ e_ {max} \ simeq 10^{17} $ eV，这解释了观察到的gamma范围内Fb的辐射，以及高启动中性中微子的发射。
We propose the model of the global structure of the electromagnetic fields in the Fermi bubbles (FBs), which makes possible the proton regular acceleration up to ultra-high energies. The poloidal and the toroidal magnetic fields, as well as the radial electric field, turn to have a structure similar to fields that exist in jets ejected out from active galactic nuclei (AGN). A powerful source of relativistic particles observed in the centre of the Galaxy and associated with the rotating supermassive black hole (SMBH) Sgr A* can energize the FB and keeps its active for a long time. The absence of accretion onto a BH and thus the absence of a relativistic jet does not mean that there is no loss of rotational energy of BH. In the case of FB, the energy lost by BH can keep the FB activity. The regular FBs structure could be formed by inheritance from a relativistic jet that presumably existed in the active past of the Galaxy $ 10^7 $ years ago, or by processes near the Galaxy centre existing during the entire life cycle of the Galaxy. The acceleration of protons in electromagnetic fields of FB are found up to energies $ E_{max} \simeq 10^{17} $ eV, which explains the observed radiation of FB in the gamma range, as well as the emission of high-energy neutrinos.
