High-Redshift Radio Galaxies: Probing the Assembly of Massive Galaxies and Clusters

Andrew J. Humphrey

Abstract
Powerful radio galaxies at high-redshift typically reside in significantly over-dense regions of the Universe (e.g. proto-clusters) and are hosted by giant elliptical galaxies, or their progenitors. Because of this, they can play an important role in helping us to understand the assembly both of massive galaxies and of galaxy clusters; their association with 100-kpc scale Lyman-alpha emitting nebulae also gives us an alternative perspective from which to understand the nature of high-redshift Lyman-alpha 'blobs'. In this seminar I will describe results from several published or ongoing investigations which use high redshift radio galaxies in this capacity, using observations from VLT, Keck, GTC, the James Clerk Maxwell Telescope, and the Atacama Submillimeter Telescope Experiment.
