A Scalable Hybrid FPGA/GPU FX Correlator
Jonathon Kocz,Lincoln J. Greenhill,Benjamin R. Barsdell,Gianni Bernardi,Gianni Bernardi,Andrew Jameson,Michael A. Clark,Michael A. Clark,J. Craig,Danny C. Price,G. B. Taylor,Frank K. Schinzel,Dan Werthimer +12 more
TL;DR: In this paper, a Packetized Correlator architecture that applies Field Programmable Gate Arrays (FPGAs) to the O(N) "F-stage" transforming time domain to frequency domain data, and GPUs to the X-stage performing an outer product among spectra for each antenna is presented.

Scintillation in the Circinus Galaxy H2O Megamasers
Jamie McCallum,Jamie McCallum,Simon Ellingsen,David L. Jauncey,James E. J. Lovell,Lincoln J. Greenhill +5 more
TL;DR: In this paper, the authors present observations of the 22 GHz water vapor megamasers in the Circinus galaxy made with the Tidbinbilla 70 m telescope, which confirm the rapid variability seen earlier by Greenhill et al.

TL;DR: In this paper, the authors carried out multi-wavelength observations of the nearby (z = 0.046) rich, merging galaxy cluster Abell 3376 with the Murchison Widefield Array (MWA) and obtained the spectra of these relics over the frequency range 80-1400 MHz.
