Results from EDGES High-band. I. Constraints on Phenomenological Models for the Global 21 cm Signal
TL;DR: In this article, the authors report constraints on the global $21$ cm signal due to neutral hydrogen at redshifts between 14.8 and 6.5 GHz with the EDGES high-band instrument.
Journal ArticleDOI
Calibration of the EDGES High-Band Receiver to Observe the Global 21-cm Signature from the Epoch of Reionization
TL;DR: In this paper, a Monte Carlo approach is used to estimate the sky-average brightness temperature from the 21-cm line emitted during the Epoch of Reionization (EoR) in the redshift range 14 and z & 6.
Journal ArticleDOI
Results from EDGES High-Band. III. New Constraints on Parameters of the Early Universe
Raul A. Monsalve,Anastasia Fialkov,Judd D. Bowman,Alan E. E. Rogers,Thomas J. Mozdzen,Aviad Cohen,Rennan Barkana,Nivedita Mahesh +7 more
TL;DR: In this paper, the authors present new constraints on parameters of cosmic dawn and the epoch of reionization derived from the EDGES High-Band spectrum (90-190$ MHz) by evaluating global $21$ cm signals generated with the Global21cm tool.

TL;DR: Burns et al. as mentioned in this paper presented a strategy for observations of the global spectrum with a realizable instrument placed in a low-altitude lunar orbit, performing night-time 40-120 MHz spectral observations, while on the farside to avoid terrestrial radio frequency interference, ionospheric corruption and solar radio emissions.
Journal ArticleDOI
Calibration of the EDGES High-Band Receiver to Observe the Global 21-cm Signature from the Epoch of Reionization
TL;DR: In this paper, a Monte Carlo approach is used to propagate uncertainties in the receiver calibration measurements to the antenna temperature using a five-term polynomial, which yields residuals of $1$~mK or less at 95% confidence.
