Fantastic beasts and where to find them: the elusive nature of X-ray quiet black holes
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,...
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...
Vainu Bappu Observatory: the telescope town of India
A popular article describing the history and contributions of the Vainu Bappu Observatory: the telescope town of India. My affair with the observatory is also highlighted in brief.
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.
