摘要:

我们讨论了早期宇宙中超大质量黑洞的形成,以及如何用即将到来的毫米/亚毫米望远镜ALMA探测它们随后的演化。我们首先集中在黑洞形成的化学和辐射条件,特别是考虑辐射捕获和分子解离效应。然后,我们把我们的注意力转向第一个黑洞形成的晕中的磁特性,并表明湍流的存在可能导致一个磁发电机,它可以通过提供一个有效的手段来支持黑洞的形成过程中的角动量。最后,我们专注于可观察到的性能高红移黑洞相对于ALMA,并讨论如何区分化学驱动的星暴和化学驱动的X射线从黑洞。

英文摘要:

We discuss the formation of supermassive black holes in the early universe, and how to probe their subsequent evolution with the upcoming mm/sub-mm telescope ALMA. We first focus on the chemical and radiative conditions for black hole formation, in particular considering radiation trapping and molecular dissociation effects. We then turn our attention towards the magnetic properties in the halos where the first black holes form, and show that the presence of turbulence may lead to a magnetic dynamo, which could support the black hole formation process by providing an efficient means of transporting the angular momentum. We finally focus on observable properties of high-redshift black holes with respect to ALMA, and discuss how to distinguish between chemistry driven by the starburst and chemistry driven by X-rays from the black hole.
