Developing a Real Time Processing System for HERA
Paul La Plante, Peter K. G. Williams, Joshua S. Dillon
The Hydrogen Epoch of Reionization Array (HERA) is a radio telescope in the Karoo desert of South Africa endeavoring to observe Cosmic Dawn and the Epoch of Reionization. When full…
Measuring HERA's primary beam in-situ: methodology and first results
Chuneeta D. Nunhokee, Aaron R. Parsons, Nicholas S. Kern +64
The central challenge in 21~cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the…
Calibration Schemes with Scaling for Large-N Radio Interferometers Built on a Regular Grid
Deepthi B. Gorthi, Aaron R. Parsons, Joshua S. Dillon
Future generations of radio interferometers targeting the 21\,cm signal at cosmological distances with antennas could face a significant computational challenge in buil…
Redundant-Baseline Calibration of the Hydrogen Epoch of Reionization Array
Joshua S. Dillon, Max Lee, Zaki S. Ali +76
In 21 cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally-smooth astrophysical foregrounds. The Hydrogen Epo…
