Simulation-Based Cosmological Mass Calibration of XXL Galaxy Clusters using HSC Weak Lensing
Sut-Ieng Tam, Keiichi Umetsu, Adam Amara +13
We present a cosmological analysis of the X-ray-selected galaxy cluster sample from the XXL survey, employing a simulation-based inference (SBI) framework to jointly constrain cosm…

The Cosmological analysis of X-ray cluster surveys VII. Bypassing scaling relations with Lagrangian Deep Learning and Simulation-based inference
Nicolas Cerardi, Marguerite Pierre, François Lanusse +1
Galaxy clusters, the pinnacle of structure formation in our universe, are a powerful cosmological probe. Several approaches have been proposed to express cluster number counts, but…
