A study of slow and fast radio transients

The thesis focusses on the studies of an enigmatic class of millisecond radio transients, known as fast radio bursts (FRBs) and reports the discoveries of new and farthest FRBs (more than 10 billion light years away). A massive collaborated campaign was conducted for the first time to search for galaxies that host these bursts at different wavelengths. Although, the source of FRBs is still unknown, the discoveries in the thesis have contributed to the diversity of the FRB population and their properties. The thesis also reports the discovery of variable sources in a pilot survey, demonstrating the future capabilities of the next generation radio telescope.
