Spectral index of the diffuse radio background between 50 and 100 MHz

Spectral index of the diffuse radio background between 50 and 100 MHz

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 (EDGES) low-band system. EDGES employs a wide beam zenith-pointing dipole antenna centred on a declination of $-26.7^\circ$. We measure the sky …
