Primary Beam and Dish Surface Characterization at the Allen Telescope Array by Radio Holography
ATA GROUP, Shannon Atkinson, D. C. Backer +46
The Allen Telescope Array (ATA) is a cm-wave interferometer in California, comprising 42 antenna elements with 6-m diameter dishes. We characterize the antenna optical accuracy usi…
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…
The Allen Telescope Array: The First Widefield, Panchromatic, Snapshot Radio Camera for Radio Astronomy and SETI
Jack Welch, Don Backer, Leo Blitz +40
The first 42 elements of the Allen Telescope Array (ATA-42) are beginning to deliver data at the Hat Creek Radio Observatory in Northern California. Scientists and engineers are ac…
A Scalable Correlator Architecture Based on Modular FPGA Hardware, Reuseable Gateware, and Data Packetization
Aaron Parsons, Donald Backer, Henry Chen +9
A new generation of radio telescopes is achieving unprecedented levels of sensitivity and resolution, as well as increased agility and field-of-view, by employing high-performance…
