Decoding X-ray observations from centres of galaxy clusters using MCMC

TL;DR

This paper improves the analysis of X-ray data from galaxy cluster centers by correcting pressure fits to account for total gas density, enabling more accurate calculations of local free-fall times.

Contribution

It introduces a correction method for pressure fits in X-ray observations to better estimate free-fall times in galaxy clusters.

Findings

Corrected pressure fits lead to more accurate free-fall time estimates.

The revised method impacts the interpretation of cluster dynamics.

Enhanced modeling of galaxy cluster environments.

Abstract

We correct for the use of electron densities instead of total gas density in the pressure fits which were used to derive the local free-fall times (t$_{\rm ff}$) in the original paper.
