Accurate parameter inference for the Light-cone Epoch of Reionization 21-cm signal
Suman Pramanick, Anoop Krishna, Rajesh Mondal +1
The light-cone (LC) effect introduces line-of-sight (LoS) statistical inhomogeneity into the 21-cm signal. Consequently, the traditional power spectrum (PS) fails to capture the fu…
Constraining the neutral hydrogen fraction during reionization: Cross-simulation inference using power spectrum and bispectrum
Anoop Krishna, Deepthi Moorkanat, Hiten +1
The redshifted 21-cm signal is a unique probe of the early universe, particularly the Epoch of Reionization (EoR). While the 21-cm power spectrum has been the primary statistic for…
Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
Quantifying and mitigating the effect of snapshot interval in light-cone Epoch of Reionization 21-cm simulations
Suman Pramanick, Rajesh Mondal, Somnath Bharadwaj
The Epoch of Reionization (EoR) neutral Hydrogen (HI) 21-cm signal evolves significantly along the line-of-sight (LoS) due to the light-cone (LC) effect. It is important to accurat…
The Evolving Power Spectrum for the light cone Epoch of Reionization (EoR) 21-cm signal
Suman Pramanick, Somnath Bharadwaj, Khandakar Md Asif Elahi +1
The rapid evolution of the cosmological neutral hydrogen (HI) distribution during the EoR is imprinted along the line of sight (LoS) in the redshifted 21-cm signal due to the light…
