Abstract:
In recent decades, diffuse X-ray and radio sources have been detected in plenty of galaxy clusters. A strong belief that the energy evolution in galaxy clusters follows self-similarity prompted the researcher to derive empirical correlations, especially with the mass. This has led to extending and predicting observables for the objects for which prior information is insufficient in literature. However, low detectability predicted by such studies negatively impacted the systematic studies of clusters in a wide mass range, leading to a few myths in galaxy cluster physics. Strikingly, the results from numerical simulations and a few recent sensitive observations with telescopes such as uGMRT and LoFAR challenged the notion of self-similarity and energy distribution in clusters, especially towards the lower mass end. In this talk, I will present and discuss some critical findings.
