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.


Insight into the pulsar emmision mechanism using subpulse drifting: Subpulse drifting in PSR J1822−2256

Long after humans figured out that the small bright dots in the night sky were just another sun-like object, and not very long after the discovery of the neutron, in the year 1933, Baade and Zwicky theorized the existence of...


Star-forming S0 Galaxies in SDSS-MaNGA: fading spirals or rejuvenated S0s?

Galaxies are the building blocks of our universe. A comprehensive theory of how galaxies evolve with cosmic time is key to understanding how the universe turns out the way it is today. Decades of observational, theoretical and computational efforts have...
