(American Astronomical Society, 2016)
      Detection of the cosmological neutral hydrogen signal from the Epoch of Reionization, and estimation of its basic physical parameters, is the principal scientific aim of many current low-frequency radio telescopes. Here ...

    • Enabling a High Throughput Real Time Data Pipeline for a Large Radio Telescope Array with GPUs 

      Pfister, Hanspeter; Edgar, Richard G; Mitchell, Daniel A; Ord, Stephen M; Greenhill, Lincoln J.; Clark, Michael A.; Dale, Kevin; Wayth, Randall B. (Elsevier, 2010)
      The Murchison Widefield Array (MWA) is a next-generation radio telescope currently under construction in the remote Western Australia Outback. Raw data will be generated continuously at 5 GiB s\(^{−1}\), grouped into 8 s ...
