JoXSZ:星系团的联合X-SZ拟合器

JoXSZ: Joint X-SZ fitter for galaxy clusters

Fabio Castagna, Stefano Andreon

摘要:

热Sunyaev-Zeldovich(SZ)效应和星系团X射线辐射的高分辨率观测越来越广泛,为研究星系团内介质的热力学性质提供了独特的条件。我们提出了JoXSZ,贝叶斯前向建模Python代码,旨在共同适应SZ数据和三维X射线数据立方体。JoXSZ能够推导出星系团的热力学配置文件的第一次充分和一致地利用所有信息中包含的观测。JoXSZ将在不久的将来在GitHub上公开发布。

英文摘要:

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 asset to the study of the thermodynamic properties of the intracluster medium. We present JoXSZ, a Bayesian forward-modelling Python code designed to jointly fit the SZ data and the three dimensional X-ray data cube. JoXSZ is able to derive the thermodynamic profiles of galaxy clusters for the first time making full and consistent use of all the information contained in the observations. JoXSZ will be publicly available on GitHub in the near future.
