Radiometer Calibration using Machine Learning
S. A. K. Leeney, H. T. J. Bevins, E. de Lera Acedo +35
Radiometers are crucial instruments in radio astronomy, forming the primary component of nearly all radio telescopes. They measure the intensity of electromagnetic radiation, conve…
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…
A Southern-Hemisphere all-sky radio transient monitor for SKA-Low prototype stations
M. Sokolowski, R. B. Wayth, N. D. R. Bhat +20
We present the first southern-hemisphere all-sky imager and radio-transient monitoring system implemented on two prototype stations of the low-frequency component of the Square Kil…
The Northern Cross Fast Radio Burst project. I. Overview and pilot observations at 408 MHz
Nicola T. Locatelli, Gianni Bernardi, Germano Bianchi +8
Fast radio bursts remain one of the most enigmatic astrophysical sources. Observations have significantly progressed over the last few years, thanks to the capabilities of new radi…
Signal Processing Firmware for the Low Frequency Aperture Array
Gianni Comoretto, Riccardo Chiello, Matt Roberts +22
The signal processing firmware that has been developed for the Low Frequency Aperture Array component of the Square Kilometre Array is described. The firmware is implemented on a d…
