STARFIRE-2: Can we detect the global redshifted 21-cm signal from the cosmic dawn in Earth orbit?

Yogen Pranesh, Mayuri Sathyanarayana Rao, Saurabh Singh

Detecting the redshifted global 21-cm signal from the cosmic dawn (CD) remains a major challenge due to strong terrestrial Radio Frequency Interference (RFI), particularly dominate…

Implications of SARAS3 data for Coulomb-like interacting dark matter

Shikhar Mittal, Prakhar Bansal, Harry Bevins +1

The 21-cm signal from cosmic dawn is a potentially sensitive probe of interactions between dark matter (DM) and baryons. We investigate the implications of the SARAS3 non-detection…

First Results from HERA Phase II

The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83

We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…

Global 21 cm signal: a promising probe of primordial features

Suvedha Suresh Naik, Pravabati Chingangbam, Saurabh Singh +2

Inflationary models that involve bursts of particle production generate bump-like features in the primordial power spectrum of density perturbations. These features influence the e…

Impacts and Statistical Mitigation of Missing Data on the 21cm Power Spectrum: A Case Study with the Hydrogen Epoch of Reionization Array

Kai-Feng Chen, Michael J. Wilensky, Adrian Liu +66

The precise characterization and mitigation of systematic effects is one of the biggest roadblocks impeding the detection of the fluctuations of cosmological 21cm signals. Missing…

A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline

Hugh Garsden, Philip Bull, Mike Wilensky +94

Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. T…

matvis: A matrix-based visibility simulator for fast forward modelling of many-element 21 cm arrays

Piyanat Kittiwisit, Steven G. Murray, Hugh Garsden +95

Detection of the faint 21 cm line emission from the Cosmic Dawn and Epoch of Reionisation will require not only exquisite control over instrumental calibration and systematics to a…
