マゼラン雲のOGLE高頻度サーベイから制限される惑星質量原始ブラックホール
天の川銀河バルジで観測された短時間重力マイクロレンズ現象は、浮遊惑星や広軌道を持つ系外惑星ではなく、原始ブラックホールによって引き起こされたものではない可能性が高い。
The Potential of Long-Lived Primordial Black Holes as Dark Matter and Astrophysical Particle Accelerators
Light primordial black holes (PBHs) may still exist as dark matter candidates due to the memory burden effect, and their mergers could produce detectable ultrahigh-energy cosmic rays.
Constraining Primordial Black Holes with High-Energy Neutrinos: Exploring the Impact of the Memory Burden Effect
The observation of high-energy neutrinos offers a novel method for constraining the properties of primordial black holes, particularly in light of the memory burden effect, which could significantly extend their lifespan and influence their detectability.
기억의 짐을 덜어낸 원시 블랙홀: 고에너지 중성미자 관측을 통한 제약
양자 효과로 인해 증발이 억제된 가벼운 원시 블랙홀은 현재까지 존재하며 고에너지 중성미자를 방출할 수 있으며, 이는 암흑 물질 및 초기 우주 연구에 중요한 의미를 지닌다.
Constraints on Primordial Black Holes and Small-Scale Primordial Curvature Perturbations from the Cosmic Microwave Background Measurement of the Effective Number of Relativistic Species
The existence of scalar-induced gravitational waves, generated alongside primordial black holes, could affect the effective number of relativistic species (Neff) in the early universe, providing a novel method to constrain the abundance of primordial black holes and the small-scale primordial curvature power spectrum.
原始ブラックホールにおけるスカラー誘導重力波の追加放射成分としての影響と、Neffを用いた制限
初期宇宙におけるスカラー誘導重力波（SIGW）は、宇宙の相対論的自由度Neffに影響を与える追加の放射成分として機能し、そのエネルギー密度スペクトルは原始ブラックホール（PBH）の形成と密接に関連しているため、Neffの観測データを用いることで、小スケール原始曲率摂動とPBHの存在量に制限を加えることができる。
