A Generic and Efficient E-field Parallel Imaging Correlator for Next-Generation Radio Telescopes
Nithyanandan Thyagarajan, Adam P. Beardsley, Judd D. Bowman +1
Modern radio telescopes are favouring densely packed array layouts with large numbers of antennas (). Since the complexity of traditional correlators scal…
Foregrounds in Wide-Field Redshifted 21 cm Power Spectra
Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +61
Detection of 21~cm emission of HI from the epoch of reionization, at redshifts z>6, is limited primarily by foreground emission. We investigate the signatures of wide-field measure…
The low-frequency environment of the Murchison Widefield Array: radio-frequency interference analysis and mitigation
A. R. Offringa, R. B. Wayth, N. Hurley-Walker +62
The Murchison Widefield Array (MWA) is a new low-frequency interferometric radio telescope built in Western Australia at one of the locations of the future Square Kilometre Array (…
