Low-Frequency Measurements of the CMB Spectrum
As part of an extended program to characterize the spectrum of the cosmic microwave background (CMB) at low frequencies, we have performed multiple measurements from a high‐altitude site in Calfornia. On average, these measurements suggests a CMB temperature slightly lower than measurements at highe...
