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…
Thermodynamic evolution of the galaxy cluster IDCS J1426.5+3508
S. Andreon, C. Romero, F. Castagna +8
We present resolved thermodynamic profiles out to 500 kpc, about , of the galaxy cluster IDCS J1426.5+3508 with 40 kpc resolution. Thanks to the combination of Su…
JoXSZ: Joint X-SZ fitting code for galaxy clusters
Fabio Castagna, Stefano Andreon
The thermal Sunyaev-Zeldovich (SZ) effect and the X-ray emission offer separate and highly complementary probes of the thermodynamics of the intracluster medium. We present JoXSZ,…
JoXSZ: Joint X-SZ fitter for galaxy clusters
Fabio Castagna, Stefano Andreon
High-resolution observations of the thermal Sunyaev-Zeldovich (SZ) effect and of the X-ray emission of galaxy clusters are becoming more and more widespread, offering us an unique…
PreProFit -- Pressure Profile Fitter for galaxy clusters
Fabio Castagna, Stefano Andreon
Galaxy cluster analyses based on high-resolution observations of the Sunyaev-Zeldovich (SZ) effect have become common in the last decade. We present PreProFit, the first publicly a…
