    Diffuse Radio Emission in Galaxy Clusters Insights With Primary Electron Model
    (Addis Ababa University, 2024-09) Yadessa Chewaka; Negessa Tilahun
    Diffuse extended radio sources are found as the number of galaxy clusters increases. The radio emission reveals the presence of cosmic rays and magnetic fields in the ICM. The relativistic electrons undergo diffuse radio emission and lose their energy via inverse-Compton and synchrotron losses in a short time, typically having lifetimes of about 0.1 Gyr. They could last for Gyr if significant re-acceleration is involved. Diffuse cluster radio sources are classified into radio halos, cluster radio shocks (relics), and revived AGN fossil plasma sources. This study summarizes the properties of diffuse cluster radio sources, providing significant insights and provides key insights into the complex interplay between relativistic electrons and the surrounding environment, enhancing our learning of cosmic structure formation.
