    Electron Acceleration Mechanism and the Diffused Radio Emission in Galaxy Clusters
    (Addis Ababa University, 2024-09) Hashim Jemal; Nagessa Tilahun (PhD)
    The study of electron acceleration mechanisms in galaxy clusters is crucial for understanding the origin of diffused radio emission, which provides insights into the physical processes occurring in these massive cosmic structures. As massive structures in the Universe, galaxy clusters are sites of astrophysical processes that facilitate the acceleration of relativistic electrons. The diffuse radio emission, characterized by its synchrotron radiation. Our understanding of galaxy clusters, with implications for the broader study of cosmic evolution and large-scale structure formation is one of the fascinating topics Astrophysics. The extended diffuse radio emissions in clusters are referred to as halos, relics and mini halos. The numbers of these sources grown in recent years making them to discuss their properties and different models for their origin. The origin of these diffuse sources tightly connected to the process that leads to the cluster formation themselves.
