本白皮书重点关注暗物质搜索中遇到的天体物理系统学。通常在间接和直接暗物质搜索中，天体物理系统学是对暗物质敏感性的主要限制因素。正如暗物质搜索有多种形式一样，背景也有多种形式。我们试图涵盖使用光子（无线电和伽马射线）到宇宙射线、中微子和引力波进行暗物质搜索的主要系统学。例子包括宇宙信使的天体物理来源及其可以模仿暗物质特征的相互作用。反过来，这些又取决于了解宇宙环境（气体分布、磁场配置）以及相关核天体物理学的相应研究。我们还涵盖了用于探测暗物质（从黑洞到矮星系）的天体和星系的天体物理学。最后，我们介绍了与探测暗物质分布和运动学相关的天体物理学背景，这些背景影响了广泛的暗物质研究。未来，多信使天文学的兴起以及利用其研究暗物质的新颖分析方法，将提供各种战略方法来继续增强我们对天体物理背景的理解，从而提高对暗物质的敏感性。
This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysical systematics are a major limiting factor to sensitivity to dark matter. Just as there are many forms of dark matter searches, there are many forms of backgrounds. We attempt to cover the major systematics arising in dark matter searches using photons -- radio and gamma rays -- to cosmic rays, neutrinos and gravitational waves. Examples include astrophysical sources of cosmic messengers and their interactions which can mimic dark matter signatures. In turn, these depend on commensurate studies in understanding the cosmic environment -- gas distributions, magnetic field configurations -- as well as relevant nuclear astrophysics. We also cover the astrophysics governing celestial bodies and galaxies used to probe dark matter, from black holes to dwarf galaxies. Finally, we cover astrophysical backgrounds related to probing the dark matter distribution and kinematics, which impact a wide range of dark matter studies. In the future, the rise of multi-messenger astronomy, and novel analysis methods to exploit it for dark matter, will offer various strategic ways to continue to enhance our understanding of astrophysical backgrounds to deliver improved sensitivity to dark matter.
