First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to per…
Calibration and 21-cm Power Spectrum Estimation in the Presence of Antenna Beam Variations
Ronniy C. Joseph, C. M. Trott, R. B. Wayth +1
Detecting a signal from the Epoch of Reionisation (EoR) requires an exquisite understanding of galactic and extra-galactic foregrounds, low frequency radio instruments, instrumenta…
Science with the Murchison Widefield Array: Phase I Results and Phase II Opportunities
A. P. Beardsley, M. Johnston-Hollitt, C. M. Trott +56
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80300 MHz) southern sky. Since beginning operations in mid 2013, the MWA…
A VOEvent based automatic trigger system for the Murchison Widefield Array
P. J. Hancock, G. E. Anderson, A. Williams +22
The Murchison Widefield Array (MWA) is an electronically steered low frequency (\,MHz) radio interferometer, with a `slew' time less than 8seconds. Low frequency (\…
The status of 21cm interferometric experiments
Cathryn M. Trott, Jonathan C. Pober
Interferometric experiments of the reionization era offer the advantages of measuring power in spatial modes with increased sensitivity afforded by multiple independent sky measure…
Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
A high time resolution study of the millisecond pulsar J2241-5236 at frequencies below 300 MHz
D. Kaur, N. D. R. Bhat, S. E. Tremblay +20
One of the major challenges for pulsar timing array (PTA) experiments is the mitigation of the effects of the turbulent interstellar medium (ISM) from timing data. These can potent…
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Cathryn M. Trott, Catherine A. Watkinson, Christopher H. Jordan +42
We apply two methods to estimate the 21~cm bispectrum from data taken within the Epoch of Reionisation (EoR) project of the Murchison Widefield Array (MWA). Using data acquired wit…
Robust statistics toward detection of the 21 cm signal from the Epoch of Reionisation
Cathryn M. Trott, Shih Ching Fu, Steven Murray +26
We explore methods for robust estimation of the 21 cm signal from the Epoch of Reionisation (EoR). A Kernel Density Estimator (KDE) is introduced for measuring the spatial temperat…
