Detecting Pulsar Polarization below 100 MHz with the Long Wavelength Array
V. Dike, G. B. Taylor, J. Dowell +1
Using the first station of the Long Wavelength Array (LWA1), we examine polarized pulsar emission between 25 and 88 MHz. Polarized light from pulsars undergoes Faraday rotation as…
Altitudinal dependence of meteor radio afterglows measured via optical counterparts
K. S. Obenberger, J. M. Holmes, J. D. Dowell +4
Utilizing the all-sky imaging capabilities of the LWA1 radio telescope along with a host of all-sky optical cameras, we have now observed 44 optical meteor counterparts to radio af…
Probing Jovian Decametric Emission with the Long Wavelength Array Station 1
T. E. Clarke, C. A. Higgins, Jinhie Skarda +12
New observations of Jupiter's decametric radio emissions have been made with the Long Wavelength Array Station 1 (LWA1) which is capable of making high quality observations as low…
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…
Pulsar Observations Using the First Station of the Long Wavelength Array and the LWA Pulsar Data Archive
K. Stovall, P. S. Ray, J. Blythe +7
We present initial pulsar results from the first station of the Long Wavelength Array (LWA1) obtained during the commissioning period of LWA1 and early science results. We present…
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…
