Abstract: | 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. |
