Description
Galaxy clusters are the largest gravitationally bounded systems in the universe. Almost 80% of their content is dark matter (DM), while 15% is in the form of hot gas permeating the Intra Cluster Medium (ICM). It is believed that a relativistic population of protons have been accumulated through the formation history of the galaxy clusters. This component should interact with ambient protons and photons producing charged and neutral pions leading to production of secondary electrons and gamma-rays. Here we show the analysis using LHAASO WCDA to search for a diffuse signal in a sample of nearby galaxy clusters.
