  • Study of the Galactic Photon Dominated Region in Rho Ophiuchus A 
    CHOUDHURY, SPANDAN (2018-05)
    Photon Dominated Regions(PDR) are predominantly neutral regions in the interstellar medium(ISM), which contains both atomic and molecular gas. Physical properties of the PDRs are governed primarily by far-ultraviolet photons ...
  • 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 ...
