论文摘要
在高红移处观察类星体在黑洞形成理论中呈现了一个谜。为了采购此类对象，人们通常依靠在早期存在重种子（$ m \ of 10^{4-6} \，m _ {\ odot} $）。不幸的是，在标准的天体物理环境中，这些重种子的形成很难实现。在这里，我们调查了超导宇宙弦循环是否可以在早期宇宙中获得足够强的过度，以解决这一谜团。 We review a set of direct collapse conditions under which a primordial gas cloud will undergo monolithic collapse into a massive black hole (forming with a mass of $M_{BH} \approx 10^5 \, M_{\odot}$ at $z \approx 300$ in our scenario), and systematically show how superconducting cosmic string loops can satisfy such conditions in regions of the $Gμ-I$参数空间。
The observation of quasars at high redshifts presents a mystery in the theory of black hole formation. In order to source such objects, one often relies on the presence of heavy seeds ($M \approx 10^{4-6} \, M_{\odot}$) in place at early times. Unfortunately, the formation of these heavy seeds are difficult to realize within the standard astrophysical context. Here, we investigate whether superconducting cosmic string loops can source sufficiently strong overdensities in the early universe to address this mystery. We review a set of direct collapse conditions under which a primordial gas cloud will undergo monolithic collapse into a massive black hole (forming with a mass of $M_{BH} \approx 10^5 \, M_{\odot}$ at $z \approx 300$ in our scenario), and systematically show how superconducting cosmic string loops can satisfy such conditions in regions of the $Gμ-I$ parameter space.
