  • Radio Spectral Index Distribution in Galaxy Cluster Radio Halos 
    SHWETA, A. (Dept. of Physics, 2019-06)
    Radio Halos are steep spectrum, diffuse, Mpc-sized objects associated with the intra-cluster medium of merging clusters of galaxies. Despite 50 years since their discovery, the energy source of synchrotron emitting electrons ...
  • Galaxy Clusters as Cosmological Probes 
    SHARMA, ARINDAM (2020-04)
    Galaxy clusters form the largest gravitationally bound structures in the Universe. Galaxy clusters form at rare peaks in the initial density fluctuation field in the Universe. Therefore their abundance is very sensitive ...
