The energy spectrum of the CMB is extremely close to that of a perfect blackbody with a temperature of . This is expected because in the early Universe matter and radiation are in thermal equilibrium. However, at redshifts , several mechanisms, both standard and non-standard, can modify the CMB spectrum and introduce departures from a blackbody spectrum. These departures are commonly referred to as CMB spectral distortions and mostly concern the averag…
