Hello! I'm Céline Gouin,
postdoctoral research at IAP in Paris
working on Cosmology & Astrophysics

I am working on the large scale structures of the Universe by using both hydrodynamical cosmological simulations and large galaxy surveys.

I am focused on probing galaxy cluster environments, where filaments connect to clusters which are the nodes of the large scale cosmic web.

I am currently working on the influence of large-scale cosmic web environments on the evolution of galaxy clusters, from proto-cluster (z>2) to clusters, in the context of the upcoming WEAVE data.
