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…
