AI总结:

研究提出通过恒星-物体和气体吸积在核团中形成超大质量黑洞的机制,预测高红移下的潮汐破坏事件率,并解释其对星系核形成的影响。

摘要:

超大质量黑洞(SMBH)的增长可能通过核星团中快速的天体物理黑洞合并发生,这种合并在高红移时形成中间质量黑洞种子。该模型预测的潮汐破坏事件率比紧凑物体捕获高一个数量级。根据我们对SMBH成因的解释,预测的潮汐破坏事件率在高红移时可被探测到。由此产生的密集气体囊状物形成紧凑的星系核,每个核包含一个中心大质量黑洞星,其质量在解析度内与气体、恒星和大质量黑洞相当,如各种小红点光谱特征所推断的。

英文摘要:

Supermassive black hole (SMBH) growth plausibly occurs via runaway astrophysical black hole mergers in nuclear star clusters that form intermediate mass black hole seeds at high redshifts. Such a model yields an order-of-magnitude higher rate of tidal disruption events than that of compact-object captures. Our prediction, normalized to our proposed resolution of SMBH seeding, yields detectable tidal disruption event rates at high redshift. The resulting dense gas cocoons generate compact galactic nuclei, each incorporating a central, massive, black hole star, with comparable masses in gas, stars, and massive black holes within a scale of around a parsec as inferred from the various Little Red Dot spectral signatures.
