论文摘要
原始黑洞（PBHS）是宇宙中暗物质的吸引人的候选人，但受到理论和观察性约束的严重限制。我们将专注于扩展到Kerr黑洞的霍金蒸发极限。特别是，我们将根据索恩（Thorne）的旋转极限，讨论将原始孔和恒星起源的黑色孔区分开的可能性。我们还将回顾各向同性的外层次伽马射线背景约束，并表明``窗口''PBH可以构成所有暗物质，这在很大程度上取决于PBH旋转。最后，我们将考虑所谓的行星9是原始黑洞的可能性。
Primordial Black Holes (PBHs) are appealing candidates for dark matter in the universe but are severely constrained by theoretical and observational constraints. We will focus on the Hawking evaporation limits extended to Kerr black holes. In particular, we will discuss the possibility to distinguish between black holes of primordial and of stellar origins based on the Thorne limit on their spin. We will also review the isotropic extragalactic gamma ray background constraints and show that the ``window'' in which PBHs can constitute all of the dark matter depends strongly on the PBH spin. Finally, we will consider the possibility that the so-called Planet 9 is a primordial black hole.
