Constraining cosmology and ionization history with combined 21 cm power spectrum and global signal measurements
Adrian Liu, Aaron R. Parsons
Improvements in current instruments and the advent of next-generation instruments will soon push observational 21 cm cosmology into a new era, with high significance measurements o…
Eliminating the optical depth nuisance from the CMB with 21 cm cosmology
Adrian Liu, Jonathan R. Pritchard, Rupert Allison +3
Amongst standard model parameters that are constrained by cosmic microwave background (CMB) observations, the optical depth stands out as a nuisance parameter. While provid…
The Cosmic Dawn and Epoch of Reionization with the Square Kilometre Array
L. V. E. Koopmans, J. Pritchard, G. Mellema +42
Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR) (15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of sou…
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…
