A milestone of modern cosmology was the prediction and serendipitous discovery of the cosmic microwave background (CMB), the radiation leftover after decoupling from matter in the early evolutionary stages of the Universe. A prediction of the standard hot Big-Bang model is the linear increase with redshift of the black-body temperature of the CMB (TCMB). This radiation excites the rotational levels of some interstellar molecules, including carbon monoxide (CO), which can serve as cosmic…

Estimation of the Cosmic Microwave Background Temperature from Atomic C I and Molecular CO Lines in the Interstellar Medium of Early Galaxies
The linear increase of the cosmic microwave background (CMB) temperature with cosmological redshift, TCMB = T0(1+z), is a prediction of the standard cosmological ΛCDM model. There are currently two

Constraining the evolution of the CMB temperature with SZ measurements from Planck data
The CMB temperature-redshift relation, TCMB(z)=T0(1+z), is a key prediction of the standard cosmology but is violated in many non-standard models. Constraining possible deviations from this law is an

Tests of the CMB temperature-redshift relation, CMB spectral distortions and why adiabatic photon production is hard
In the expanding Universe, the average temperature of the cosmic microwave background (CMB) is expected to depend like TCMB ∝ (1 + z) on redshift z. Adiabatic photon production (or destruction) or
