Descrizione

Abstract:The thermal Sunyaev-Zeldovich (SZ) effect and the X-ray
emission offer separate and highly complementary probes of the
thermodynamics of the intracluster medium.
I will present JoXSZ, the first publicly available code designed to
jointly fit SZ and X-ray data coming from various instruments to derive
the thermodynamic profiles of galaxy clusters. JoXSZ follows a fully
Bayesian forward-modelling approach and improves upon most current and
not publicly available analyses.
JoXSZ accounts for beam smearing and data analysis transfer function and
adopts flexible parametrization for the thermodynamic profiles. The code
is written in Python and the users are free to customise their analysis
in accordance with their needs and requirements. JoXSZ is publicly
available on GitHub (https://github.com/fcastagna/joxsz).
