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…
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…
RHINO: A large horn antenna for detecting the 21cm global signal
Philip Bull, Ahmed El-Makadema, Hugh Garsden +11
The sky-averaged brightness temperature of the 21cm line from neutral hydrogen provides a sensitive probe of the thermal state of the intergalactic medium, particularly before and…
Mitigating calibration errors from mutual coupling with time-domain filtering of 21 cm cosmological radio observations
N. Charles, N. S. Kern, R. Pascua +80
The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). This has led to the construction of low-frequency radio i…
Investigating Mutual Coupling in the Hydrogen Epoch of Reionization Array and Mitigating its Effects on the 21-cm Power Spectrum
E. Rath, R. Pascua, A. T. Josaitis +78
Interferometric experiments designed to detect the highly redshifted 21-cm signal from neutral hydrogen are producing increasingly stringent constraints on the 21-cm power spectrum…
Sensitivity of Bayesian 21 cm power spectrum estimation to foreground model errors
Jacob Burba, Philip Bull, Michael J. Wilensky +3
Power spectrum estimators are an important tool in efforts to detect the 21 cm brightness temperature fluctuations from neutral hydrogen at early times. An initial detection will l…
High-dimensional inference of radio interferometer beam patterns I: Parametric model of the HERA beams
Michael J. Wilensky, Jacob Burba, Philip Bull +6
Accurate modelling of the primary beam is an important but difficult task in radio astronomy. For high dynamic range problems such as 21cm intensity mapping, small modelling errors…
Statistical estimation of full-sky radio maps from 21cm array visibility data using Gaussian constrained realizations
Katrine A. Glasscock, Philip Bull, Jacob Burba +2
An important application of next-generation wide-field radio interferometers is making high dynamic range maps of radio emission. Traditional deconvolution methods like CLEAN can g…
