Receiver design for the REACH global 21-cm signal experiment

Ian L. V. Roque, Nima Razavi-Ghods, Steven H. Carey +35

We detail the the REACH radiometric system designed to enable measurements of the 21-cm neutral hydrogen line. Included is the radiometer architecture and end-to-end system simulat…

Search for the Epoch of Reionisation with HERA: Upper Limits on the Closure Phase Delay Power Spectrum

Pascal M. Keller, Bojan Nikolic, Nithyanandan Thyagarajan +80

Radio interferometers aiming to measure the power spectrum of the redshifted 21 cm line during the Epoch of Reionisation (EoR) need to achieve an unprecedented dynamic range to sep…

Bayesian jackknife tests with a small number of subsets: Application to HERA 21cm power spectrum upper limits

Michael J. Wilensky, Fraser Kennedy, Philip Bull +2

We present a Bayesian jackknife test for assessing the probability that a data set contains biased subsets, and, if so, which of the subsets are likely to be biased. The test can b…

The REACH radiometer for detecting the 21-cm hydrogen signal from redshift 7.5 to 28

E. de Lera Acedo, D. I. L. de Villiers, N. Razavi-Ghods +31

Observations of the 21-cm line from primordial hydrogen promise to be one of the best tools to study the early epochs of the Universe: the Dark Ages, the Cosmic Dawn, and the subse…

Characterization Of Inpaint Residuals In Interferometric Measurements of the Epoch Of Reionization

Michael Pagano, Jing Liu, Adrian Liu +75

Radio Frequency Interference (RFI) is one of the systematic challenges preventing 21cm interferometric instruments from detecting the Epoch of Reionization. To mitigate the effects…

Improved Constraints on the 21 cm EoR Power Spectrum and the X-Ray Heating of the IGM with HERA Phase I Observations

The HERA Collaboration, Zara Abdurashidova, Tyrone Adams +92

We report the most sensitive upper limits to date on the 21 cm epoch of reionization power spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization…
