论文摘要
在$ z \ sim $ 15-20的原子冷却光环中,在灾难性的bary子倒塌过程中形成的超大质量原始恒星可能是宇宙中第一个类星体的起源。但是,迄今为止尚无模拟遵循这些光环在足够高或足够长以确定崩溃是否真正产生SMS的时间的分辨率上的演变。在这里,我们报告了原子冷却光环中巴里昂崩溃的新宇宙学模拟,这足以使SMS形成并死于直接浪潮黑洞(DCBHS)。我们发现,建立此类恒星所需的高进口率确实持续到他们的生命结束,并可能促进其BHS的迅速增长。我们的模拟还表明,SMS的二元倍数甚至很小的倍数可以分别以低自旋和高自旋光环形成。这一发现提出了令人兴奋的前景,即从与{\ em James Webb Space望远镜{\ Em James Webb Space望远镜}和接下来的十年中的{\ em James Webb Space望远镜的近红外和潮汐破坏事件中发现引力波和潮汐破坏事件。
Supermassive primordial stars forming during catastrophic baryon collapse in atomically-cooling halos at $z \sim$ 15 - 20 may be the origin of the first quasars in the universe. However, no simulation to date has followed the evolution of these halos at resolutions that are high enough or for times that are long enough to determine if collapse actually produces SMSs. Here we report new cosmological simulations of baryon collapse in atomically-cooled halos for times that are long enough for SMSs to form and die as direct-collapse black holes (DCBHs). We find that the high infall rates required to build up such stars do persist until the end of their lives and could fuel the rapid growth of their BHs thereafter. Our simulations also demonstrate that binary and even small multiples of SMSs can form in low-spin and high-spin halos, respectively. This discovery raises the exciting prospect of detecting gravitational waves from DCBH mergers with LISA and tidal disruption events in the near infrared with the {\em James Webb Space Telescope} and ground-based telescopes in the coming decade.
