Bayesian approach to constraining the properties of ionized bubbles during reionization
Raghunath Ghara, T. Roy Choudhury
A possible way to study the reionization of cosmic hydrogen is by observing the large ionized regions (bubbles) around bright individual sources, e.g., quasars, using the redshifte…

Cosmological implications of the composite spectra of galactic X-ray binaries constructed using MAXI data
Nazma Islam, Raghunath Ghara, Biswajit Paul +2
We have investigated the long term average spectral properties of galactic X-ray binaries in the energy range of 3-20 keV, using long term monitoring data from MAXI -Gas Slit Camer…

Impact of Ly heating on the global 21-cm signal from the Cosmic Dawn
Raghunath Ghara, Garrelt Mellema
The resonance scattering of Ly photons with neutral hydrogen atoms in the intergalactic medium not only couples the spin temperature to the kinetic temperature but also leads to…
