Inferring radio beams from sparse sampling patterns: a case study with the Murchison Widefield Array
Michael J. Wilensky, Aman Chokshi
Accurate primary-beam models are essential for high-dynamic-range radio experiments, particularly searches for the redshifted 21-cm signal from the Epoch of Reionisation, where bea…
Improved Modeling for Moving Sources of Radio Frequency Interference and Impact on Flagging Strategies
Jade M. Ducharme, Jonathan C. Pober, Michael J. Wilensky
Radio frequency interference (RFI) is a major challenge for low-frequency radio experiments targeting the redshifted 21-cm signal from the Epoch of Reionization. Many important RFI…
High Dimensional Beam Inference II: Inference of a Perturbed HERA Beam from Simulated Visibility Data
Michael J. Wilensky, Philip Bull, Nicolas Fagnoni
Accurate beam modeling is important in many radio astronomy applications. In this paper, we focus on beam modeling for 21-cm intensity mapping experiments using radio interferomete…
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…
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…
