Can missing physics in gravitational waveforms mimic false violations of general relativity?
General theory of relativity proposed by Albert Einstein in 1915 has passed all the experimental and observational tests with flying colors. Gravitational waves from the merger of compact binaries such as black holes and neutron stars provide a unique opportunity...
Using a pseudo-Kerr formalism to study accretion and wind flows around rotating black holes
Hydrodynamic flows around black holes is a fascinating area of research that provides a window into the processes that power relativistic jets and energetic particle acceleration. However, this is a challenging task when studied using the full general relativistic framework....
Exploring the topology of hydrogen distribution in the early universe
We study how galaxies and other sources in the early universe change the neutral universe or InterGalactic Medium (IGM) into the ionized one. We compare different kinds of source models and how they ionize the neutral universe which mainly consists...
Astrophysical autopsy of a cosmic demise
As the saying goes, “न कंचित् शाश्वतम्” (lit. Nothing is permanent), and hence the nature of this universe. The ever-evolving twinkles in the starry night are also non-discriminate towards this concept. If a star is born, it ought to die....
Accounting for the presence of dust in galaxies
Dust is as ubiquitous in galaxies as are stars, gases and dark matter. Although dust forms less than 1% of the mass of the interstellar medium, its importance can be gauged from the fact that dust reprocesses more than half...
Spreading the joy of science - The science outreach activities during the Young Astronomer’s Meeting, 2022
A summary of science outreach performed during the Young Astronomer’s Meeting, 2022.
