超大质量黑洞

Supermassive Black Holes

Fulvio Melia

摘要:

超大质量黑洞通常被认为是自然界中最具破坏性的力量。但近年来,它们在范式上发生了戏剧性的转变。这些天体可能对早期宇宙结构的形成至关重要,它们催生了恒星形成的爆发和原星系凝聚的成核。大爆炸后产生的所有辐射中可能有一半可以归因于它们,现在已知它们的数量超过3亿。其中最容易接近的是位于我们银河系的中心。在接下来的几页中,我们将研究使我们达到这一点的证据,我们将理解为什么许多人期望在这十年内实际拍摄银河系中心黑洞的事件视界。

英文摘要:

Supermassive black holes have generally been recognized as the most destructive force in nature. But in recent years, they have undergone a dramatic shift in paradigm. These objects may have been critical to the formation of structure in the early universe, spawning bursts of star formation and nucleating proto-galactic condensations. Possibly half of all the radiation produced after the Big Bang may be attributed to them, whose number is now known to exceed 300 million. The most accessible among them is situated at the Center of Our Galaxy. In the following pages, we will examine the evidence that has brought us to this point, and we will understand why many expect to actually image the event horizon of the Galaxy's central black hole within this decade.
