论文摘要
发现类星体形成的种子黑洞极具挑战性。但是，应该在本地矮人星系中发现那些未成长为超质量的种子，应作为100-10 $^5 $ m $ _ {\ odot} $的中间质量黑洞（IMBH）。深度多波长度调查的使用表明，矮星系中存在着积极积累IMBH（低质量AGN）的人群，至少在$ z \ sim $ 3中存在。这些星系的黑洞占用部分表明，早期的宇宙种子黑洞是由气体直接塌陷形成的，这是由于低质量端的黑洞 - 糖缩放关系的扁平化而加强的。然而，这种情况受到AGN反馈可以对矮星系产生强烈影响的发现，这种情况质疑，这意味着矮星系中的低质量AGN可能不是早期种子黑洞的未触及的文物。这对种子黑洞形成模型具有重要意义。
Detecting the seed black holes from which quasars formed is extremely challenging; however, those seeds that did not grow into supermassive should be found as intermediate-mass black holes (IMBHs) of 100-10$^5$ M$_{\odot}$ in local dwarf galaxies. The use of deep multiwavelength surveys has revealed that a population of actively accreting IMBHs (low-mass AGN) exists in dwarf galaxies at least out to $z\sim$3. The black hole occupation fraction of these galaxies suggests that the early Universe seed black holes formed from direct collapse of gas, which is reinforced by the possible flattening of the black hole-galaxy scaling relations at the low-mass end. This scenario is however challenged by the finding that AGN feedback can have a strong impact on dwarf galaxies, which implies that low-mass AGN in dwarf galaxies might not be the untouched relics of the early seed black holes. This has important implications for seed black hole formation models.
