Particle emission from galactic objects due to interactions with primordial black holes

这是在哥德堡大学与Marek Abramowicz教授和他的工作组合作完成的一个为期两年的项目的提案。任务分配是研究原始黑洞对银河系天体的影响。例如地球、太阳或像白矮星和中子星这样的致密天体。在宇宙的早期阶段，原始黑洞(PBH)被认为已经形成，其中一些至今仍存在。这样的黑洞比典型的天体物理黑洞要小得多。他们有质量的MPBH≥1015g。建议研究这些黑洞在穿越物质时的影响。特别是，计划研究形成激波和吸积环境的可能性。当PBH穿过致密物质，从而引起密度起伏时，就会发生这样的激波。这个项目的最后一步是计算得到的粒子光谱，并将它们与实验数据进行比较。在这里，带电粒子光谱，如质子的光谱，以及光子和中微子光谱，可以与目前GLAST、Pamela和IceCube等实验的数据进行比较。

This is the proposal for a 2-year project to be accomplished at the University of Gothenburg, in collaboration with Prof. Marek Abramowicz and his working group. The assignment of tasks is the investigation of the impact of primordial black holes on astrophysical objects in the Milky Way. Examples are the Earth, the Sun, or compact objects like white dwarfs and neutron stars. In the early phase of the Universe, primordial black holes (PBHs) are believed to have formed, some of them still existing today. Such black holes are much smaller than typical astrophysical black holes. They have a mass of Mpbh ≥ 1015g. The influence of these black holes while traversing matter is proposed to be studied. In particular, the possibility of the formation of shock and accretion environments is planned to be examined. Such shocks can occur when a PBH traverses dense matter and thereby causes density fluctuations. The final step of this project is the calculation of the resulting particle spectra and their comparison with experimental data. Here, charged particle spectra like those of protons, but also photon and neutrino spectra can be compared to data from current experiments like GLAST, PAMELA and IceCube.
