HI intensity mapping with the MIGHTEE survey: power spectrum estimates
Sourabh Paul, Mario G. Santos, Junaid Townsend +5
Intensity mapping (IM) with neutral hydrogen is a promising avenue to probe the large scale structure of the Universe. In this paper, we demonstrate that using the 64-dish MeerKAT…
CMB constraints on a physical model of reionization
Tirthankar Roy Choudhury, Suvodip Mukherjee, Sourabh Paul
We study constraints on allowed reionization histories by comparing predictions of a physical semi-numerical model with secondary temperature and polarization anisotropies of the c…
Inevitable imprints of patchy reionization on the cosmic microwave background anisotropy
Sourabh Paul, Suvodip Mukherjee, Tirthankar Roy Choudhury
Reionization of the cosmic neutral hydrogen by the first stars in the Universe is an inhomogeneous process which produces spatial fluctuations in free electron density. These fluct…
