Array Element Coupling in Radio Interferometry I: A Semi-Analytic Approach
Alec T. Josaitis, Aaron Ewall-Wice, Nicolas Fagnoni +1
We derive a general formalism for interferometric visibilities, which considers first-order antenna-antenna coupling and assumes steady-state, incident radiation. We simulate such…
Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array
Dara Storer, Joshua S. Dillon, Daniel C. Jacobs +75
We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outlier…
Radio antenna design for sky-averaged 21 cm cosmology experiments: the REACH case
J. Cumner, E. De Lera Acedo, D. I. L. de Villiers +35
Following the reported detection of an absorption profile associated with the 21~cm sky-averaged signal from the Cosmic Dawn by the EDGES experiment in 2018, a number of experiment…
