摘要
LIGO 的发现重新点燃了原初黑洞（BH）可能构成宇宙中部分乃至全部暗物质（DM）的猜想。此类猜想源于：1）观测到的 BH 并合率，2）其不寻常的质量，3）其低/零自旋，以及 4）独立发现的具有高振幅且与未分辨宇宙 X 射线背景（CXB）相干的宇宙红外背景（CIB）涨落信号。在此我们总结利用 2020 年代预期可用的仪器和工具通过电磁观测解决这一重要问题的前景。这些前景有望取得显著且可能关键的进展。我们表明，在未来十年，新的天基和地基电磁仪器结合同步的理论工作，应能为长期考虑的原初 BH 与 DM 之间的联系提供关键启示。具体而言，该计划下的新数据和方法将涉及：I）利用 Euclid 和 WFIRST 高精度探测源扣除后 CIB 的空间谱，及其与利用 eROSITA 和 Athena 的未分辨宇宙 X 射线背景的相干性；II）利用 OGLE、Gaia、LSST 和 WFIRST 对银河系晕 BH 介入引起的银河系恒星微透镜的高级搜寻；III）WFIRST、LSST 以及潜在 Euclid 和 JWST 的即将开展巡天中的超新星（SNe）透镜；IV）为理解下一代 CMB 实验下的 PBH 吸积与演化及其对宇宙微波背景（CMB）各向异性影响的高级理论工作；V）涉及超暗矮星系、脉冲星计时和宇宙类星体透镜的稳定性与性质的更好新样本和理论理解。
