Realisation of a low frequency SKA Precursor: The Murchison Widefield Array
S. J. Tingay, R. Goeke, J. N. Hewitt +56
The Murchison Widefield Array is a low frequency (80 - 300 MHz) SKA Precursor, comprising 128 aperture array elements distributed over an area of 3 km diameter. The MWA is located…
Fast Holographic Deconvolution: a new technique for precision radio interferometry
Ian Sullivan, Miguel Morales, Bryna Hazelton +48
We introduce the Fast Holographic Deconvolution method for analyzing interferometric radio data. Our new method is an extension of A-projection/software-holography/forward modeling…
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…
Accelerating Radio Astronomy Cross-Correlation with Graphics Processing Units
M. A. Clark, P. C. La Plante, L. J. Greenhill
We present a highly parallel implementation of the cross-correlation of time-series data using graphics processing units (GPUs), which is scalable to hundreds of independent inputs…
Digital Instrumentation for the Radio Astronomy Community
Aaron Parsons, Dan Werthimer, Donald Backer +21
Time-to-science is an important figure of merit for digital instrumentation serving the astronomical community. A digital signal processing (DSP) community is forming that uses sha…
GPUs for data processing in the MWA
S. Ord, L. Greenhill, R. Wayth +4
The MWA is a next-generation radio interferometer under construction in remote Western Australia. The data rate from the correlator makes storing the raw data infeasible, so the da…
