From ANN to BNN: Inferring Reionization Parameters using Uncertainty-aware Emulators of 21-cm Summaries

Yashrajsinh Mahida, Sanjay Kumar Yadav, Suman Majumdar +6

Inferring astrophysical parameters from radio interferometric observations of the redshifted 21-cm signal from the Epoch of Reionization (EoR) is a challenging yet crucial task. Th…

21cm Epoch of Reionisation Power Spectrum with Closure Phase using the Murchison Widefield Array

Himanshu Tiwari, Nithyanandan Thyagarajan, Cathryn M. Trott +1

The radio interferometric closure phases can be a valuable tool for studying cosmological {H\scriptsize{I}}~from the early Universe. Closure phases have the advantage of being immu…

Measuring the global 21-cm signal with the MWA-II: improved characterisation of lunar-reflected radio frequency interference

Himanshu Tiwari, Benjamin McKinley, Cathryn M. Trott +1

Radio interferometers can potentially detect the sky-averaged signal from the Cosmic Dawn (CD) and the Epoch of Reionisation (EoR) by studying the Moon as a thermal block to the fo…

Modelling the energy distribution in CHIME/FRB Catalog-1

Siddhartha Bhattacharyya, Somnath Bharadwaj, Himanshu Tiwari +1

We characterize the intrinsic properties of any FRB using its redshift , spectral index and energy in units of emitted across $2128 - 2848\; {\…

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…

Improving constraints on the reionization parameters using 21-cm bispectrum

Himanshu Tiwari, Abinash Kumar Shaw, Suman Majumdar +2

Radio interferometric experiments aim to constrain the reionization model parameters by measuring the 21-cm signal statistics, primarily the power spectrum. However the Epoch of Re…
