PublicationA New Era of Intracluster Light Studies with JWST
Still largely unexplored, the diffuse light in clusters of galaxies traces the past and ongoing buildup of these massive structures. Here we present the first...

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...
