The multi-frequency angular power spectrum in parameter studies of the cosmic 21-cm signal
Rajesh Mondal, Garrelt Mellema, Steven G. Murray +1
The light-cone effect breaks the periodicity and statistical homogeneity (ergodicity) along the line-of-sight direction of cosmological emission/absorption line surveys. The spheri…
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…
Interpreting LOFAR 21-cm signal upper limits at z~9.1 in the context of high-z galaxy and reionisation observations
Bradley Greig, Andrei Mesinger, Léon V. E. Koopmans +11
Using the latest upper limits on the 21-cm power spectrum at from the Low Frequency Array (LOFAR), we explore regions of parameter space which are inconsistent with t…
The impact of non-Gaussianity on the Epoch of Reionization parameter forecast using 21-cm power spectrum measurements
Abinash Kumar Shaw, Somnath Bharadwaj, Rajesh Mondal
Measurements of the Epoch of Reionization (EoR) 21-cm signal hold the potential to constrain models of reionization. In this paper we consider a reionization model with three astro…
