Keywords原始ブラックホール
Outline of Research at the Start

インフレーション中に生成された量子揺らぎを起源とする高密度領域が,宇宙初期に重力崩壊を起こした結果形成されるブラックホールを原始ブラックホール(PBH)と呼ぶ.PBH の存在量はその質量ごとに観測的制限が得られており,そこからインフレーションモデルを制限できる.また,近年は重力波源であるブラックホール連星の起源としても注目されている.本研究では初期揺らぎの統計性を素に,相対論的な非球対称重力崩壊シミュレーションを用いてPBH の質量,角運動量分布を明らかにする方法を提案する.

Outline of Final Research Achievements

Primordial Black Holes are the black holes which formed in the early universe. The purpose of this work is to develop the procedure for the estimation of the abundance of primordial black holes and the typical mass and the angular momentum of them. As for the statistical treatment, we developed the procedure based on the peak theory. We have also developed the numerical simulation of a non-spherical primordial black hole. These achievements give basis of more realistic analysis on the dynamics and the abundance in the future.

Academic Significance and Societal Importance of the Research Achievements

原始ブラックホール(PBH:Primordial Black Hole)は重力波によって観測された連星ブラックホールや暗黒物質の候補として学術的にも社会的にも関心を集めている.PBHがこれらの天体を説明する可能性を追求するためにはPBHの統計的取り扱いとその非線形ダイナミクスの数値的解析が必要不可欠である.本研究課題においては,それらについて今後のより詳細な研究につながる道筋をつけたという点で大きな意義を持つ.
