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…
Ionospheric Attenuation of Polarized Foregrounds in 21 cm Epoch of Reionization Measurements: A Demonstration for the HERA Experiment
Zachary E. Martinot, James E. Aguirre, Saul A. Kohn +1
Foregrounds with polarization states that are not smooth functions of frequency present a challenge to HI Epoch of Reionization (EoR) power spectrum measurements if they are not cl…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
The HERA-19 Commissioning Array: Direction Dependent Effects
Saul A. Kohn, James E. Aguirre, Paul La Plante +64
Foreground power dominates the measurements of interferometers that seek a statistical detection of highly-redshifted HI emission from the Epoch of Reionization (EoR). The chromati…
Reionization Models Classifier using 21cm Map Deep Learning
Sultan Hassan, Adrian Liu, Saul Kohn +3
Next-generation 21cm observations will enable imaging of reionization on very large scales. These images will contain more astrophysical and cosmological information than the power…
Improved 21 cm Epoch Of Reionization Power Spectrum Measurements with a Hybrid Foreground Subtraction and Avoidance Technique
Joshua Kerrigan, Jonathan Pober, Zaki Ali +16
Observations of the 21cm Epoch of Reionization (EoR) signal are dominated by Galactic and extragalactic foregrounds. The need for foreground removal has led to the development of t…
