本文研究费子暗物质形成致密天体的可能性，通过微引力透镜约束质量并分析吸积辐射，认为其非银河系中心GeV过剩来源，但可解释部分缺失重子。
AI 中文摘要
费米子暗物质粒子仍然是宇宙暗物质含量最有力的候选者之一，然而直接探测实验尚未获得任何阳性结果。在这项工作中，我们研究了这类粒子形成由简并压力支持的致密引力束缚天体的可能性。通过对微引力透镜巡天的广泛回顾，我们推导出对这些致密天体质量的约束。我们进一步分析了重子物质向这些天体的吸积过程，并评估了它们的热性质和辐射性质。估算的爆发辐射能量远低于与银河系中心GeV过剩相关的能量，这表明这些致密天体不太可能是观测到的信号的来源。我们的分析表明，混合暗物质和重子物质天体可能潜在地解释目前未观测到的重子物质的一部分，从而为宇宙中缺失重子的一部分提供可能的解释。
英文摘要
Fermionic dark matter particles remain one of the most compelling candidates for the dark matter content of the Universe, yet no positive results have been obtained from direct detection experiments. In this work, we investigate the possibility that such particles form compact gravitationally bound objects supported by degeneracy pressure. Through an extensive review of microlensing surveys, we derive constraints on the masses of these compact objects. We further analyze the accretion of baryonic matter onto these objects and evaluate their thermal and radiative properties. The estimated burst emission is found to be well below the energies associated with the Galactic Center GeV excess, suggesting that these compact objects are unlikely to be the source of the observed signal. Our analysis suggests that admixed dark matter and baryonic matter objects could potentially account for a fraction of the presently unobserved baryonic matter, thereby providing a possible explanation for a fraction of the missing baryons in the Universe.
