How Cluster Pressure Profiles Scale: Mass, Redshift, and Intrinsic Scatter

S. Andreon, F. Castagna

[shortened] The thermal pressure profile of the intracluster medium is critical for cluster cosmology and understanding galaxy-cluster astrophysics. We determine the population-ave…

Estimating the heterogeneity of pressure profiles within a complete sample of 55 galaxy clusters: a Bayesian Hierarchical Model

Fabio Castagna, Stefano Andreon, Marco Landoni +1

Galaxy clusters exhibit heterogeneity in their pressure profiles, even after rescaling, highlighting the need for adequately sized samples to accurately capture variations across t…

A Serverless Architecture for Efficient and Scalable Monte Carlo Markov Chain Computation

Fabio Castagna, Alberto Trombetta, Marco Landoni +1

Computer power is a constantly increasing demand in scientific data analyses, in particular when Markov Chain Monte Carlo (MCMC) methods are involved, for example for estimating in…

The flat entropy profile at the outskirts of the Abell 2244 galaxy cluster

S. Andreon, A. Moretti, H. Bohringer +1

Entropy is an advantageous diagnostics to study the thermodynamic history of the intracluster plasma of galaxy clusters. We present the entropy profile of the Abell 2244 galaxy clu…

Many-probes multi-object spatially-resolved analyses of galaxy clusters in the big data era

Fabio Castagna, Stefano Andreon, Alberto Trombetta +1

The thermal Sunyaev-Zeldovich (SZ) effect and the X-ray emission offer separate and highly complementary probes of the thermodynamics of the intracluster medium, particularly on th…
