Astronomers find cold atomic gas playing peek-a-boo around a powerful quasar

The interaction of radio jets with gas associated with the host galaxy could play an important role in determining their morphology. Such interactions may be more prevalent at high redshifts, when these powerful AGN are still the assembly sites of...


A comparison of the properties of Narrow Line and the Broad Line Seyfert galaxies

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...


Precise Measurement of Flux Density of Radio Emissions from the Sun using Day-time Celestial Radio Sources

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...


What makes radio-quiet AGN radio-quiet? A polarization perspective

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...


Gravitational Waves in an Inhomogeneous Universe

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...


One year of CosmicVarta

CosmicVarta celebrates its first birthday today! Hurray! It was a wonderful year indeed. Today, we take a look back at our journey and briefly talk about our future plans.
