      • Analytical Formalism to Study the 21 cm Signal from Cosmic Dawn and Epoch of Reionization 

        Raste, Janakee
        The epoch of Cosmic Dawn and Reionization is one of the most important time periods of the universe when first sources of radiation like stars and galaxies were formed, and they changed the properties of their surrounding ...
      • The Formation and Evolution of Bars, and Its Impact on Galaxy Dynamics 

        Kataria, Sandeep Kumar
        In this thesis we have studied bar formation and evolution using N-body simulations. We have focused on the effect of bulge mass and concentration on bar formation and evolution, and derived a new bar formation criterion. ...
      • Nonlinear and Geometric Properties of Accreting Compact Sources Based on Spectral and Timing Analyses 

        Adegoke, Oluwashina K
        We study the spectro-temporal properties of the black hole X-ray binaries (BHXBs) GRS 1915+105 and IGR J17091-3624 with data from RXTE, Chandra and XMM-Newton. From the analysis result, we propose models of accretion ...
      • Observational study of Core-Collapse Supernovae 

        Singh, Avinash
        The advent of dedicated surveys for studying transient events has invoked a great interest in the study of supernovae (SNe). The rate of discovery of SNe has hence gone up ten-fold relinquishing their diversity. SNe not ...
      • Spectro-temporal signatures of accretion flows around Galactic Black Holes 

        Sreehari, H
        A system of two stars in which one is a black hole (BH) is referred to as a black hole binary (BHB). In a BHB, it is possible to have mass transfer from the secondary star (companion star) to the primary black hole. ...
      • Thermal and Non-thermal Processes in Young Star clusters 

        Gupta, Siddhartha
        Massive stars are energetic sources of radiation and stellar wind. They are mostly born together in dense cold clouds in the interstellar medium (ISM). Regions in the ISM that are densely populated by stars are known as ...
