Relativistic Particles in Star-Forming Galaxies

这个项目旨在了解星系的演化是如何被充满星际空间的被称为宇宙射线的相对论性粒子所塑造的。我们对宇宙射线如何与非相对论性星际物质相互作用了解甚少，这反过来又限制了我们对宇宙射线如何影响星系的理解。该项目试图通过计算宇宙射线-物质相互作用如何产生光和中微子来解决这个问题，我们可以使用当前和未来的望远镜观察到这些光和中微子，使我们能够利用这些望远镜的观测结果来解决宇宙射线-物质相互作用的问题。这将解决宇宙射线如何影响星系演化的问题，从而代表了星系形成理论的重大进步。

This project aims to understand how galactic evolution is shaped by the relativistic particles known as cosmic rays that fill interstellar space. We understand only poorly how cosmic rays interact with non-relativistic interstellar matter, which in turn limits our understanding of how they affect galaxies. The project seeks to resolve this question by calculating how cosmic ray-matter interaction gives rise to light and neutrinos that we can observe using current and future telescopes, enabling us to use observations from these telescopes to solve the problem of cosmic ray-matter interaction. This would resolve the question of how cosmic rays shape galaxy evolution, and thus represent a substantial advance in the theory of galaxy formation.
