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…
The Aperture Array Verification System 1: System overview and early commissioning results
P. Benthem, R. Wayth, E. de Lera Acedo +51
The design and development process for the Square Kilometre Array (SKA) radio telescope, the Low Frequency Aperture Array component, was progressed during the SKA pre-construction…
Digitizing MEXART -- System Overview and Verification
Alessio Magro, Josef Borg, Riccardo Chiello +7
The Mexican Array Radio Telescope (MEXART), located in the state of Michoacan in Mexico, has been operating in an analog fashion, utilizing a Butler Matrix to generate fixed beams…
Characterization of the SKA1-Low prototype station Aperture Array Verification System 2
Giulia Macario, Giuseppe Pupillo, Gianni Bernardi +16
The low frequency component of the Square Kilometre Array (SKA1-Low) will be an aperture phased array located at the Murchison Radio-astronomy Observatory (MRO) site in Western Aus…
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…
The Formalism in the Geometric Trinity of Gravity
Salvatore Capozziello, Andrew Finch, Jackson Levi Said +1
The geometric trinity of gravity offers a platform in which gravity can be formulated in three analogous approaches, namely curvature, torsion and nonmetricity. In this vein, gener…
