We have built a new model for the lens system SDSS J1004+4112 including the recently measured time delay of the fourth quasar image. This time delay has a...
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...
Using first-of-their-kind observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de...
An international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has discovered a large reservoir of hot gas in the still...
Today in the multiple use hall of IACTEC in La Laguna the XXXII Canary Islands Winter School of Astrophysics, organised by the Instituto de Astrofísica de...
In order to connect galaxy clusters to their progenitor protoclusters, we must constrain the star formation histories within their member galaxies and the...
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...
Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...
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...
