摘要

詹姆斯·韦伯太空望远镜（JWST）的观测带来了一系列突破性的发现，挑战了我们目前对早期星系形成的理解。在134亿到135亿年前的宇宙黎明时期（\(z\sim 11-14\)红移时期），大量的星系被惊人地发现，远远超出了理论预测。此外，在\(z>4\)上发现了许多微弱的agn，其中包含超大质量黑洞。早期宇宙发生了什么？本文概述了这些最新发现。

Early galaxies and supermassive black holes discovered by the James Webb Space Telescope

Observations by the James Webb Space Telescope (JWST) have led to a series of groundbreaking discoveries that challenge our current understanding of early galaxy formation. A large number of galaxies have been surprisingly identified during the epoch of cosmic dawn, the redshift of \(z\sim 11-14\), 13.4 to 13.5 billion years ago, far exceeding theoretical predictions. Additionally, many faint AGNs hosting supermassive black holes have been discovered at \(z>4\). What was happening in the early universe? This article provides an overview of these latest findings.

期刊介绍： Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered. The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing. Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
