在诞生时寻找直接坍缩的黑洞
Finding Direct-Collapse Black Holes at Birth
摘要：
直接坍缩黑洞（DCBH）目前是宇宙中第一批类星体起源的主要竞争者之一，其中300多个现在已经在$z >$ 6发现。但是，在原子冷却的晕中诞生的DCBH本身并不能保证它会在$z \sim$ 7之前成为类星体，晕还必须位于冷吸积流中，或者稍后与一系列其他富含气体的晕合并，这些晕能够为BH的快速增长提供燃料。在这里，我们提出了近红外光度DCBHs出生在冷吸积流中，他们注定要成长到10 $^9$ M $_{\odot}$的$z \sim$ 7。我们的观测结果，这是来自宇宙学模拟与恩佐辐射流体力学，揭示了DCBH可以发现的詹姆斯韦伯太空望远镜在$z \lesssim$ 20和强透镜DCBH可能会发现在未来的宽视场调查的欧几里得和宽视场红外太空望远镜在$z \lesssim$ 15。
英文摘要：
Direct-collapse black holes (DCBHs) are currently one of the leading contenders for the origins of the first quasars in the universe, over 300 of which have now been found at $z >$ 6. But the birth of a DCBH in an atomically-cooling halo does not by itself guarantee it will become a quasar by $z \sim$ 7, the halo must also be located in cold accretion flows or later merge with a series of other gas-rich halos capable of fueling the BH's rapid growth. Here, we present near infrared luminosities for DCBHs born in cold accretion flows in which they are destined to grow to 10$^9$ M$_{\odot}$ by $z \sim$ 7. Our observables, which are derived from cosmological simulations with radiation hydrodynamics with Enzo, reveal that DCBHs could be found by the James Webb Space Telescope at $z \lesssim$ 20 and strongly-lensed DCBHs might be found in future wide-field surveys by Euclid and the Wide-Field Infrared Space Telescope at $z \lesssim$ 15.
