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…
Design and Commissioning of the LWA1 Radio Telescope
S. W. Ellingson, J. Craig, J. Dowell +2
LWA1 is a new large radio telescope array operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 260 pairs of dipole-type antennas who…
A wide-band, active antenna system for long wavelength radio astronomy
Brian C. Hicks, Nagini Paravastu-Dalal, Kenneth P. Stewart +9
We describe an "active" antenna system for HF/VHF (long wavelength) radio astronomy that has been successfully deployed 256-fold as the first station (LWA1) of the planned Long Wav…
First Light for the First Station of the Long Wavelength Array
G. B. Taylor, S. W. Ellingson, N. E. Kassim +32
The first station of the Long Wavelength Array (LWA1) was completed in April 2011 and is currently performing observations resulting from its first call for proposals in addition t…
The LWA1 Radio Telescope
S. W. Ellingson, G. B. Taylor, J. Craig +10
LWA1 is a new radio telescope operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 258 pairs of dipole-type antennas whose outputs a…
The First Station of the Long Wavelength Array
Patricia Henning, Steven W. Ellingson, Gregory B. Taylor +6
The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz. Upon completion, LWA will consist of 53 phased array "statio…
