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…

Hydrogen Epoch of Reionization Array (HERA) Phase II Deployment and Commissioning

Lindsay M. Berkhout, Daniel C. Jacobs, Zuhra Abdurashidova +93

This paper presents the design and deployment of the Hydrogen Epoch of Reionization Array (HERA) phase II system. HERA is designed as a staged experiment targeting 21 cm emission m…

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…

Bayesian estimation of cross-coupling and reflection systematics in 21cm array visibility data

Geoff G. Murphy, Philip Bull, Mario G. Santos +76

Observations with radio arrays that target the 21-cm signal originating from the early Universe suffer from a variety of systematic effects. An important class of these are reflect…

Direct Optimal Mapping Image Power Spectrum and its Window Functions

Zhilei Xu, Honggeun Kim, Jacqueline N. Hewitt +79

The key to detecting neutral hydrogen during the epoch of reionization (EoR) is to separate the cosmological signal from the dominating foreground radiation. We developed direct op…

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…
