Validation of EDGES Low-Band Antenna Beam Model
Nivedita Mahesh, Judd D. Bowman, Thomas J. Mozdzen +4
The response of the antenna is a source of uncertainty in measurements with the Experiment to Detect the Global EoR Signature (EDGES). We aim to validate the beam model of the low-…
Spectral Index of the Diffuse Radio Background Between 50 and 100 MHz
Thomas J. Mozdzen, Nivedita Mahesh, Raul A. Monsalve +2
We report the spectral index of diffuse radio emission between 50 and 100 MHz from data collected with two implementations of the Experiment to Detect the Global EoR Signature (EDG…
Improved Measurement of the Spectral Index of the Diffuse Radio Background Between 90 and 190 MHz
Thomas. J. Mozdzen, Judd. D. Bowman, Raul. A. Monsalve +1
We report absolutely calibrated measurements of diffuse radio emission between 90 and 190 MHz from the Experiment to Detect the Global EoR Signature (EDGES). EDGES employs a wide b…
One-Port Direct/Reverse Method for Characterizing VNA Calibration Standards
Raul A. Monsalve, Alan E. E. Rogers, Thomas J. Mozdzen +1
This paper introduces a one-port method for estimating model parameters of VNA calibration standards. The method involves measuring the standards through an asymmetrical passive ne…
Calibration of the EDGES High-Band Receiver to Observe the Global 21-cm Signature from the Epoch of Reionization
Raul A. Monsalve, Alan E. E. Rogers, Judd D. Bowman +1
The EDGES High-Band experiment aims to detect the sky-average brightness temperature of the -cm signal from the Epoch of Reionization (EoR) in the redshift range $14.8 \gtrsim…
Limits on Foreground Subtraction from Chromatic Beam Effects in Global Redshifted 21 cm Measurements
Thomas J. Mozdzen, Judd D. Bowman, Raul A. Monsalve +1
Foreground subtraction in global redshifted 21 cm measurements is limited by frequency-dependent (chromatic) structure in antenna beam patterns. Chromatic beams couple angular stru…
