| Abstract | The measurement of present-day temperature of the Cosmic Microwave Background (CMB), T0 = 2.72548± 0.00057 K (1σ), made by the Far-InfraRed Absolute Spectrophotometer (FIRAS) as recalibrated by the Wilkinson Microwave Anisotropy Probe (WMAP), is one of the most precise measurements ever made in Cosmology. On the other hand, estimates of the Hubble Constant, H0, obtained from measurements of the CMB temperature fluctuations assuming the standard ΛCDM model exhibit a large (4.1σ) tension when compared with low-redshift, model-independent observations. Recently, some authors argued that a slightly change in T0 could alleviate or solve the H0-tension problem. Here, we investigate evidence for a hotter or colder universe by performing an independent analysis from currently available temperature-redshift T (z) measurements. Our analysis (parametric and non-parametric) shows a good agreement with the FIRAS measurement and a discrepancy of ≥ 1.9σ from the T0 values required to solve the H0 tension. This result reinforces the idea that a solution of the H0-tension problem in fact requires either a better understanding of the systematic errors on the H0 measurements or new physics. | |||
