Large HI optical depth and Redshifted 21-cm signal from cosmic dawn
Kanan K. Datta, Raghunath Ghara, Ariful Hoque +1
The HI 21-cm optical depth () can be considerably large as the kinetic and spin temperature of the inter-galactic medium (IGM) is expected to be very low during cosmic dawn. I…
A maximum likelihood estimate of the parameters of the FRB population
Siddhartha Bhattacharyya, Himanshu Tiwari, Somnath Bharadwaj +1
We consider a sample of non-repeating FRBs detected at Parkes, ASKAP, CHIME and UTMOST each of which operates over a different frequency range and has a different detection cr…
CII and HI 21-cm line intensity mapping from the EoR: Impact of the light-cone effect on auto and cross-power spectra
Chandra Shekhar Murmu, Suman Majumdar, Kanan K. Datta
CII line intensity mapping (LIM) is a potential technique to probe the early galaxies from the Epoch of Reionization (EoR). Several experiments e.g. CONCERTO, TIME, CCAT-p are unde…
The Epoch of Reionization 21-cm Bispectrum: The impact of light-cone effects and detectability
Rajesh Mondal, Garrelt Mellema, Abinash Kumar Shaw +2
We study the spherically averaged bispectrum of the 21-cm signal from the Epoch of Reionization (EoR). This metric provides a quantitative measurement of the level of non-Gaussiani…
Redshifted 21-cm bispectrum II: Impact of the spin temperature fluctuations and redshift space distortions on the signal from the Cosmic Dawn
Mohd Kamran, Raghunath Ghara, Suman Majumdar +5
We present a study of the 21-cm signal bispectrum (which quantifies the non-Gaussianity in the signal) from the Cosmic Dawn (CD). For our analysis, we have simulated the 21-cm sign…
Redshifted 21-cm Bispectrum I: Impact of the Redshift Space Distortions on the Signal from the Epoch of Reionization
Suman Majumdar, Mohd Kamran, Jonathan R. Pritchard +4
The bispectrum can quantify the non-Gussianity present in the redshifted 21-cm signal produced by the neutral hydrogen (HI) during the epoch of reionization (EoR). Motivated by thi…
