Optimized Beam Sculpting with Generalized Fringe-Rate Filters
Aaron R. Parsons, Adrian Liu, Zaki S. Ali +1
We generalize the technique of fringe-rate filtering, whereby visibilities measured by a radio interferometer are re-weighted according to their temporal variation. As the Earth ro…
PAPER-64 Constraints On Reionization II: The Temperature Of The z=8.4 Intergalactic Medium
Jonathan C. Pober, Zaki S. Ali, Aaron R. Parsons +24
We present constraints on both the kinetic temperature of the intergalactic medium (IGM) at z=8.4, and on models for heating the IGM at high-redshift with X-ray emission from the f…
PAPER-64 Constraints on Reionization: The 21cm Power Spectrum at z=8.4
Zaki S. Ali, Aaron R. Parsons, Haoxuan Zheng +20
In this paper, we report new limits on 21cm emission from cosmic reionization based on a 135-day observing campaign with a 64-element deployment of the Donald C. Backer Precision A…
New Limits on Polarized Power Spectra at 126 and 164 MHz: Relevance to Epoch of Reionization Measurements
David Moore, James E. Aguirre, Saul Kohn +15
Polarized foreground emission is a potential contaminant of attempts to measure the fluctuation power spectrum of highly redshifted 21 cm HI emission from the epoch of reionization…
