PublicationComprehensive Gas Characterization of a z = 2.5 Protocluster: A Cluster Core Caught in the Beginning of Virialization?
In order to connect galaxy clusters to their progenitor protoclusters, we must constrain the star formation histories within their member galaxies and the...
PublicationDetection and Characterization of Galaxy Systems at Intermediate Redshift.
This thesis is divided into two very related parts. In the first part we implement and apply a galaxy cluster detection method, based on multiband observations...
PublicationEmergence of an Ultrared, Ultramassive Galaxy Cluster Core at z = 4
Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...
PublicationGalaxy pairs and clusters in a lambda CDM universe: Bridging observation and simulation
I use computer simulations to examine the evolution of close galaxy pair counts and the formation of galaxy clusters. I show that the evolution of the close...
PublicationGrowing a `cosmic beast': observations and simulations of MACS J0717.5+3745
We present a gravitational lensing and X-ray analysis of a massive galaxy cluster and its surroundings. The core of MACS J0717.5+3745 (M(R
