特别报告员谈话:Cosmic Ray直接

Rapporteur Talk: Cosmic Ray Direct

Philipp Mertsch

摘要:

这是第37届国际宇宙线大会(ICRC 2021)关于宇宙线直接追踪的报告,广泛涵盖了与银河系起源的带电宇宙射线(CR)有关的贡献。这里强调的贡献是观测和理论性质,旨在解释当地的流量的CR以及研究更广泛的动力学效应的CR。本文评述了CR电子和正电子、质子和氦以及重核及其同位素的空间实验的新数据。我们涵盖了CR加速的一些模型和它们在银河尺度上的反馈。伽玛射线的漫发射,只要它涉及到在太阳系附近的CR光谱和CR各向异性简要介绍。一些即将进行的和拟议的实验强调接近尾声。

英文摘要:

This is the report on the cosmic ray direct track of the 37th International Cosmic Ray Conference (ICRC 2021), broadly covering the contributions relating to charged cosmic rays (CRs) of Galactic origin. The contributions highlighted here are of both observational and theoretical nature and aim at interpreting the local fluxes of CRs as well as studying the wider dynamical effects of CRs. New data from space-borne experiments on CR electrons and positrons, proton and helium as well as heavier nuclei and their isotopes are reviewed. We cover some models of CR acceleration and their feedback on Galactic scales. Diffuse emission in gamma-rays as far as it concerns the CR spectra in the immediate vicinity of the solar system and CR anisotropies are covered briefly. Some upcoming and proposed experiments are highlighted towards the end.
