Predictions for measuring the 21-cm multi-frequency angular power spectrum using SKA-Low
Rajesh Mondal, Abinash Kumar Shaw, Ilian T. Iliev +5
The light-cone (LC) effect causes the mean as well as the statistical properties of the redshifted 21-cm signal to change with frequency (or cosmic t…
Constraining warm dark matter power spectrum using the cross-correlation of HI 21 cm signal and the Lyman- forest
Anjan Kumar Sarkar, Ashis Kumar Pal, Tapomoy Guha Sarkar
We have considered the prospects for measuring the cross Warm Dark Matter (WDM) power spectrum of the redshifted HI 21-cm signal and the Lyman- forest and thereby constraining W…
A method to determine the evolution history of the mean neutral Hydrogen fraction
Rajesh Mondal, Somnath Bharadwaj, Ilian T. Iliev +4
The light-cone (LC) effect imprints the cosmological evolution of the redshifted 21-cm signal along the frequency axis which is the line of sight (L…
An analytical method to simulate the HI 21-cm visibility signal for intensity mapping experiments
Anjan Kumar Sarkar, Somnath Bharadwaj, Visweshwar Ram Marthi
Simulations play a vital role in testing and validating HI 21-cm power spectrum estimation techniques. Conventional methods use techniques like N-body simulations to simulate the s…
Fisher Matrix Based Predictions for Measuring the z = 3.35 Binned 21-cm Power Spectrum using the Ooty Wide Field Array (OWFA)
Anjan Kumar Sarkar, Somnath Bharadwaj, Sk. Saiyad Ali
We use the Fisher matrix formalism to predict the prospects of measuring the redshifted 21-cm power spectrum in different -bins using observations with the upcoming Ooty Wide Fi…
