GMRT observation towards detecting the Post-reionization 21-cm signal

Abhik Ghosh, Somnath Bharadwaj, Sk. Saiyad Ali +1

We have analyzed 610 MHz GMRT observations towards detecting the redshifted 21-cm signal from z=1.32. The multi-frequency angular power spectrum C_l(Delta nu) is used to characteri…

Gravitational Wave Detection Using Redshifted 21-cm Observations

Somnath Bharadwaj, Tapomoy Guha Sarkar

A gravitational wave traversing the line of sight to a distant source produces a frequency shift which contributes to redshift space distortion. As a consequence, gravitational wav…
