Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations
N. Barry, M. Wilensky, C. M. Trott +27
Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the M…
PUMA: The Positional Update and Matching Algorithm
J. L. B. Line, R. L. Webster, B. Pindor +2
We present new software to cross-match low-frequency radio catalogues: the Positional Update and Matching Algorithm (PUMA). PUMA combines a positional Bayesian probabilistic approa…
CHIPS: The Cosmological HI Power Spectrum Estimator
Cathryn M. Trott, Bart Pindor, Pietro Procopio +49
Detection of the cosmological neutral hydrogen signal from the Epoch of Reionization, and estimation of its basic physical parameters, is the principal scientific aim of many curre…
Power spectrum analysis of ionospheric fluctuations with the Murchison Widefield Array
Shyeh Tjing Loi, Cathryn M. Trott, Tara Murphy +45
Low-frequency, wide field-of-view (FoV) radio telescopes such as the Murchison Widefield Array (MWA) enable the ionosphere to be sampled at high spatial completeness. We present th…
Measuring Phased-Array Antenna Beampatterns with High Dynamic Range for the Murchison Widefield Array using 137 MHz ORBCOMM Satellites
A. R. Neben, R. F. Bradley, J. N. Hewitt +26
Detection of the fluctuations in 21 cm line emission from neutral hydrogen during the Epoch of Reionization in thousand hour integrations poses stringent requirements on calibratio…
A Digital-Receiver for the Murchison Widefield Array
Thiagaraj Prabu, K. S. Srivani, D. Anish Roshi +55
An FPGA-based digital-receiver has been developed for a low-frequency imaging radio interferometer, the Murchison Widefield Array (MWA). The MWA, located at the Murchison Radio-ast…
