标题： General relativistic effects on photon spectrum emitted from dark matter halos around primordial black holes

摘要： 我们研究了广义相对论效应对从原初黑洞周围的晕暗物质（或湮没）粒子发射的光谱的影响。 由于黑洞附近的强引力场引起的引力红移，光谱经历了显著的修改，导致展宽现象。 光谱的这种特征性变化呈现出独特的观测标志。 未来对这些光谱特征的观测可能会为包含原初黑洞和粒子暗物质的混合暗物质情景提供关键证据。 显示英文摘要

摘要： We investigate general relativistic effects on the photon spectrum emitted from decaying (or annihilating) particle dark matter in the halo surrounding a primordial black hole. The spectrum undergoes significant modification due to gravitational redshifts, which induces broadening as a result of the intense gravitational field near the black hole. This characteristic alteration in the photon spectrum presents a unique observational signature. Future observations of such spectral features may provide critical evidence for a mixed dark matter scenario, involving both primordial black holes and particle dark matter.
