On dark matter - dark radiation interaction and cosmic reionization
Subinoy Das, Rajesh Mondal, Vikram Rentala +1
An intriguing possibility for the dark sector of our universe is that the dark matter particle could interact with a dark radiation component. If the non-gravitational interactions…
Quantifying the non-Gaussianity in the EoR 21-cm signal through bispectrum
Suman Majumdar, Jonathan R. Pritchard, Rajesh Mondal +3
The epoch of reionization (EoR) 21-cm signal is expected to be highly non-Gaussian in nature and this non-Gaussianity is also expected to evolve with the progressing state of reion…
Towards simulating and quantifying the light-cone EoR 21-cm signal
Rajesh Mondal, Somnath Bharadwaj, Kanan K. Datta
The light-cone (LC) effect causes the Epoch of Reionization (EoR) 21-cm signal to evolve significantly along the line of sight (LoS) direction . In…
A fast estimator for the bispectrum and beyond - A practical method for measuring non-Gaussianity in 21-cm maps
Catherine A Watkinson, Suman Majumdar, Jonathan R Pritchard +1
In this paper we establish the accuracy and robustness of a fast estimator for the bispectrum - the "FFT bispectrum estimator". The implementation of the estimator presented here o…
