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…
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…
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…
