The 300 galaxy clusters: seeing the unseen

What we see is not what we understand, what we produce is what we know. In this talk, I will present what we know (or don't know) about galaxy clusters by reproducing them with different state-of-the-art hydrodynamic simulations from the300 collaboration project ( In detail, I will focus on 4 different aspects: the cluster dynamical state, the lensing crisis, the predictions with ML and the filamentary structures around the cluster.

Dr Weiguang Cui graduated from Shanghai Astronomical Observatory in 2010. He uses numerical simulations to study and understand our Universe, which includes, but not limits to, galaxy formation, galaxy cluster and group, large-scale structure and cosmology. He has worked in many different places, and he is currently the atracción de talento senior researcher at universidad autonoma de Madrid.
