论文摘要

星系合并为星系提供了一种机制,可以有效地将气体和材料驶向其核,并为中心的星爆和超级质量黑洞的积聚。反过来,活跃的核驱动银河尺度流出后来影响宿主星系的演变。与超级黑洞有关的这种变革过程的细节仍然模棱两可,部分原因是在灰尘降低的合并宿主中通常发现的中心晦涩,这也是因为在附近的世界中实验室相对较少,可以深入研究该过程。这篇评论强调了文献的当前状态,即从电磁频谱中的各个窗户中可以看出,在局部发光红外星系中获得超质量黑洞的作用。具体而言,我们讨论了活性核的多波长特征,其相关的进食和反馈过程以及在附近相互作用的星系系统中发现的多个超质量黑洞的含义,从观察性的角度来看,星系进化了星系的演化。最后,我们以未来的前景对低红色和高速度银河合并中的主动核主题如何受益于未来十年中具有无与伦比的分辨能力和灵敏度的下一代观察设施的出现。

Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes. In turn, the active nuclei drive galactic-scale outflows that subsequently impact the evolution of the host galaxies. The details of this transformative process as they pertain to the supermassive black holes remain ambiguous, partially due to the central obscuration commonly found in the dust-reddened merger hosts, and also because there are relatively few laboratories in the nearby universe where the process can be studied in depth. This review highlights the current state of the literature on the role of accreting supermassive black holes in local luminous infrared galaxies as seen from various windows within the electromagnetic spectrum. Specifically, we discuss the multiwavelength signatures of the active nucleus, its associated feeding and feedback processes, and the implications of multiple supermassive black holes found in nearby interacting galaxy systems for galaxy evolution from the observational perspective. We conclude with a future outlook on how the topic of active nuclei in low- and high-redshift galaxy mergers will benefit from the advent of next-generation observing facilities with unparalleled resolving power and sensitivity in the coming decade.
