Exploring high-redshift proto-clusters with CCAT
Proto-clusters at z>2 - the progenitor environments of today's massive clusters of galaxies - are rare, but exciting laboratories for galaxy evolution studies because they are the sites where the most massive galaxies are being assembled. As such, high-z proto-clusters often appear to be host to extreme activity such as intense star formation and black hole growth.
In this talk I describe our multi-wavelength observations of the best studied proto-cluster at z=3.1, focusing on a very unusual class of object: the Lyman-alpha 'Blobs'. Finally, I describe prospects for using CCAT as a valuable tool in the exploration of galaxy formation in larger samples of high-z proto-clusters.
