远距离射电星系及其环境

Distant Radio Galaxies and their Environments

George Miley, Carlos De Breuck

摘要:

本文综述了亮高红移射电星系(HzRGs,z > 2)的性质和性质以及它们所处的环境。HzRGs有几种不同的成分,它们相互作用-相对论等离子体,各种形式的气体,尘埃,恒星和活动星系核(AGN)。这些构建模块提供了关于早期宇宙条件的独特诊断。我们讨论了每种成分的性质。证据表明,HzRGs是大质量的形成中的星系和最亮的星系团星系在本地宇宙的祖先。HzRGs位于早期宇宙的过密区域,经常被原星团包围。我们回顾这些无线电选择原团簇的性质和性质。最后,我们考虑在未来几十年内在该领域的未来进展的潜力。已知的HzRG的概要在附录中给出。

英文摘要:

We review the properties and nature of luminous high-redshift radio galaxies (HzRGs, z > 2) and the environments in which they are located. HzRGs have several distinct constituents which interact with each other - relativistic plasma, gas in various forms, dust, stars and an active galactic nucleus (AGN). These building blocks provide unique diagnostics about conditions in the early Universe. We discuss the properties of each constituent. Evidence is presented that HzRGs are massive forming galaxies and the progenitors of brightest cluster galaxies in the local Universe. HzRGs are located in overdense regions in the early Universe and are frequently surrounded by protoclusters. We review the properties and nature of these radio-selected protoclusters. Finally we consider the potential for future progress in the field during the next few decades. A compendium of known HzRGs is given in an appendix.
