The Correlation Calibration of PAPER-64 data
Tamirat G. Gogo, Yin-Zhe Ma, Piyanat Kittiwisit +21
Observation of redshifted 21-cm signal from the Epoch of Reionization (EoR) is challenging due to contamination from the bright foreground sources that exceed the signal by several…
Characterizing Signal Loss in the 21 cm Reionization Power Spectrum: A Revised Study of PAPER-64
Carina Cheng, Aaron R. Parsons, Matthew Kolopanis +18
The Epoch of Reionization (EoR) is an uncharted era in our Universe's history during which the birth of the first stars and galaxies led to the ionization of neutral hydrogen in th…
Constraining Polarized Foregrounds for EoR Experiments I: 2D Power Spectra from the PAPER-32 Imaging Array
S. A. Kohn, J. Aguirre, C. Nunhokee +15
Current-generation low frequency interferometers constructed with the objective of detecting the high-redshift 21 cm background, aim to generate power spectra of the brightness-tem…
A Per-Baseline, Delay-Spectrum Technique for Accessing the 21cm Cosmic Reionization Signature
Aaron R. Parsons, Jonathan C. Pober, James E. Aguirre +3
A critical challenge in measuring the power spectrum of 21cm emission from cosmic reionization is compensating for the frequency dependence of an interferometer's sampling pattern,…
A Technique for Primary Beam Calibration of Drift-Scanning, Wide-Field Antenna Elements
Jonathan C. Pober, Aaron R. Parsons, Daniel C. Jacobs +6
We present a new technique for calibrating the primary beam of a wide-field, drift-scanning antenna element. Drift-scan observing is not compatible with standard beam calibration r…
