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.
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...
