论文摘要
通过星系组和星系簇扩散的弥散光是由不与任何星系结合的自由浮动恒星制成的。这被称为群内光（ICL），并具有了解这些大结构的演变的重要线索。由于技术和数据处理的进步使我们能够达到前所未有的观察深度，对这一光的研究在过去20年中引起了人们的关注。这一进展导致了该领域的开创性结果，例如指出了ICL的起源及其在星系簇中绘制暗物质的潜力。现在，我们进入了一个深入而广泛的调查时代，该时代有望揭开前所未有的淡淡的宇宙，这增加了我们对ICL的特性的日益了解，从而增加了对宇宙中最大的重力结构的形成。这篇综述的目的是总结有关ICL的最新结果，综合了该领域的当前知识，并提供了可能使未来ICL研究受益的全球视野。
The diffuse light that spreads through groups and clusters of galaxies is made of free-floating stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds important clues for understanding the evolution of these large structures. The study of this light has gained traction in the past 20 years thanks to technological and data processing advances that have permitted us to reach unprecedented observational depths. This progress has led to ground-breaking results in the field, such as pinpointing the origin of the ICL and its potential to map dark matter in clusters of galaxies. We now enter an era of deep and wide surveys that promise to uncover the faint Universe as never seen before, adding to our growing understanding of the properties of the ICL and, consequently, of the formation of the largest gravitationally bound structures in the Universe. The goal of this Review is to summarize the most recent results on ICL, synthesizing the current knowledge in the field and providing a global perspective that may benefit future ICL studies.
