First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
Complete Sampling of the Plane with Realistic Radio Arrays: Introducing the RULES Algorithm, with Application to 21 cm Foreground Wedge Removal
Vincent MacKay, Zhilei Xu, Ruby Byrne +1
We introduce the Radio-array Layout Engineering Strategy (RULES), an algorithm for designing radio arrays that achieve complete coverage of the plane, defined as, at mini…
The Murchison Widefield Array Correlator
S. M. Ord, B. Crosse, D. Emrich +64
The Murchison Widefield Array (MWA) is a Square Kilometre Array (SKA) Precursor. The telescope is located at the Murchison Radio--astronomy Observatory (MRO) in Western Australia (…
A survey for transients and variables with the Murchison Widefield Array 32-tile prototype at 154 MHz
M. E. Bell, T. Murphy, D. L. Kaplan +55
We present a search for transient and variable radio sources at 154 MHz with the Murchison Widefield Array 32-tile prototype. Fifty-one images were obtained that cover a field of v…
A study of fundamental limitations to statistical detection of redshifted HI from the epoch of reionization
Nithyanandan Thyagarajan, N. Udaya Shankar, Ravi Subrahmanyan +46
In this paper we explore for the first time the relative magnitudes of three fundamental sources of uncertainty, namely, foreground contamination, thermal noise and sample variance…
A 189 MHz, 2400 square degree polarization survey with the Murchison Widefield Array 32-element prototype
G. Bernardi, L. J. Greenhill, D. A. Mitchell +50
We present a Stokes I, Q and U survey at 189 MHz with the Murchison Widefield Array 32-element prototype covering 2400 square degrees. The survey has a 15.6 arcmin angular resoluti…
The Murchison Widefield Array: solar science with the low frequency SKA Precursor
S. J. Tingay, D. Oberoi, I. Cairns +50
The Murchison Widefield Array is a low frequency (80 - 300 MHz) SKA Precursor, comprising 128 aperture array elements (known as tiles) distributed over an area of 3 km diameter. Th…
The EoR Sensitivity of the Murchison Widefield Array
A. P. Beardsley, B. J. Hazelton, M. F. Morales +48
Using the final 128 antenna locations of the Murchison Widefield Array (MWA), we calculate its sensitivity to the Epoch of Reionization (EoR) power spectrum of red- shifted 21 cm e…
The Murchison Widefield Array
Daniel A. Mitchell, Lincoln J. Greenhill, Stephen M. Ord +57
It is shown that the excellent Murchison Radio-astronomy Observatory site allows the Murchison Widefield Array to employ a simple RFI blanking scheme and still calibrate visibiliti…
