AGNs are very luminous objects at the centre of active galaxies. The inner regions of these galaxies can not be resolved directly, yet the understanding of these regions can be achieved by employing indirect methods. In this study, we employed...
With the gravitational wave observations capturing the coalescence of compact objects, hunting for black holes has taken quite a front-row seat in astronomical observations. Here, we discuss two such detection of black holes in orbit with a main sequence companion,...
During astronomical observation, astronomers measure the amount of energy emitted by astronomical objects. This energy is generally measured in terms of the flux density of the source. At radio frequencies, these measurements are calibrated using calibrator sources, which have known...

My affair with the observatory is also highlighted in brief.
There is a lack of consensus on the origin of radio emission in radio-quiet (RQ) and radio-intermediate (RI) AGN. Primary contenders include low-power radio jets, winds, star-formation and coronal emission. Our multi-frequency, multi-scale radio polarization study has revealed a multi-component...
Space is quite inhomogeneous at small scales. These inhomogeneities may play a significant role in governing the physical phenomena at this scale. Here we have analysed the impact of these inhomogeneities on the Gravitational Wave (GW) observables. For this analysis...
