General Framework for Array Noise Analysis and Noise Performance of a Two-Element Interferometer With a Mutual-Coupling Canceler
Leonid Belostotski, Adrian T. Sutinjo, Ravi Subrahmanyan +2
This article investigates the noise performance of a two-element phased array and interferometer containing a recently introduced self-interference canceler, which in the context o…
Astrophysical Constraints from the SARAS3 non-detection of the Cosmic Dawn Sky-Averaged 21-cm Signal
H. T. J. Bevins, A. Fialkov, E. de Lera Acedo +4
Observations of the redshifted 21-cm line of atomic hydrogen have resulted in several upper limits on the 21-cm power spectrum and a tentative detection of the sky-averaged signal…
A Comprehensive Bayesian re-analysis of the SARAS2 data from the Epoch of Reionization
H. T. J. Bevins, E. de Lera Acedo, A. Fialkov +4
We present a Bayesian re-analysis of the sky-averaged 21-cm experimental data from SARAS2 using nested sampling implemented with polychord, spectrally smooth foreground modelling i…
On the detection of a cosmic dawn signal in the radio background
Saurabh Singh, Jishnu Nambissan T., Ravi Subrahmanyan +6
The astrophysics of cosmic dawn, when star formation commenced in the first collapsed objects, is predicted to be revealed as spectral and spatial signatures in the cosmic radio ba…
The Engineering Development Array 2: design, performance and lessons from an SKA-Low prototype station
Randall Wayth, Marcin Sokolowski, Jess Broderick +21
We present the Engineering Development Array 2, which is one of two instruments built as a second generation prototype station for the future Square Kilometre Array Low Frequency A…
A Floating Octave Bandwidth Cone-Disc Antenna for Detection of Cosmic Dawn
Agaram Raghunathan, Ravi Subrahmanyan, N. Udaya Shankar +9
The critical component of radio astronomy radiometers built to detect redshifted 21-cm signals from Cosmic Dawn is the antenna element. We describe the design and performance of an…
