A Lunar Farside Low Radio Frequency Array for Dark Ages 21-cm Cosmology
Jack Burns, Gregg Hallinan, Tzu-Ching Chang +20
An array of low-frequency dipole antennas on the lunar farside surface will probe a unique, unexplored epoch in the early Universe called the Dark Ages. It begins at Recombination…
The DSA-2000 -- A Radio Survey Camera
G. Hallinan, V. Ravi, S. Weinreb +25
We present the DSA-2000: a world-leading radio survey telescope and multi-messenger discovery engine for the next decade. The array will be the first true radio camera, outputting…
FARSIDE: A Low Radio Frequency Interferometric Array on the Lunar Farside
Jack Burns, Gregg Hallinan, Jim Lux +9
FARSIDE (Farside Array for Radio Science Investigations of the Dark ages and Exoplanets) is a Probe-class concept to place a low radio frequency interferometric array on the farsid…
Design and characterization of the Large-Aperture Experiment to Detect the Dark Age (LEDA) radiometer systems
D. C. Price, L. J. Greenhill, A. Fialkov +24
The Large-Aperture Experiment to Detect the Dark Age (LEDA) was designed to detect the predicted O(100)mK sky-averaged absorption of the Cosmic Microwave Background by Hydrogen in…
Bayesian constraints on the global 21-cm signal from the Cosmic Dawn
G. Bernardi, J. T. L. Zwart, D. Price +7
The birth of the first luminous sources and the ensuing epoch of reionization are best studied via the redshifted 21-cm emission line, the signature of the first two imprinting the…
Digital Signal Processing using Stream High Performance Computing: A 512-input Broadband Correlator for Radio Astronomy
J. Kocz, L. J Greenhill, B. R. Barsdell +16
A "large-N" correlator that makes use of Field Programmable Gate Arrays and Graphics Processing Units has been deployed as the digital signal processing system for the Long Wavelen…
A Scalable Hybrid FPGA/GPU FX Correlator
J. Kocz, L. J. Greenhill, B. R. Barsdell +8
Radio astronomical imaging arrays comprising large numbers of antennas, O(10^2-10^3) have posed a signal processing challenge because of the required O(N^2) cross correlation of si…
First Spectroscopic Imaging Observations of the Sun at Low Radio Frequencies with the Murchison Widefield Array Prototype
Divya Oberoi, Lynn D. Matthews, Iver H. Cairns +67
We present the first spectroscopic images of solar radio transients from the prototype for the Murchison Widefield Array (MWA), observed on 2010 March 27. Our observations span the…
Interferometric imaging with the 32 element Murchison Wide-field Array
S. M. Ord, D. A. Mitchell, R. B. Wayth +56
The Murchison Wide-field Array (MWA) is a low frequency radio telescope, currently under construction, intended to search for the spectral signature of the epoch of re-ionisation (…
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…
The Murchison Widefield Array: Design Overview
Colin J. Lonsdale, Roger J. Cappallo, Miguel F. Morales +45
The Murchison Widefield Array (MWA) is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range. It is capable of a wide range of sci…
