The Precision Array for Probing the Epoch of Reionization: 8 Station Results
Aaron R. Parsons, Donald C. Backer, Richard F. Bradley +12
We are developing the Precision Array for Probing the Epoch of Reionization (PAPER) to detect 21cm emission from the early Universe, when the first stars and galaxies were forming.…
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…
Calibration of Low-Frequency, Wide-Field Radio Interferometers Using Delay/Delay-Rate Filtering
Aaron R. Parsons, Donald C. Backer
We present a filtering technique that can be applied to individual baselines of wide-bandwidth, wide-field interferometric data to geometrically select regions on the celestial sph…
