What is Adiabatic CMB Cooling Resilience Analysis about?
This study investigates deviations from the standard adiabatic evolution of the cosmic microwave background (CMB) temperature using recent measurements from the Sunyaev-Zeldovich effect and molecular line excitation data across redshifts 0 < z ≲ 6. The findings indicate good consistency with the standard temperature-redshift relation, yielding a present-day CMB monopole temperature of T0 = 2.744 ± 0.019 K and a best-fit value of β = -0.0106 ± 0.0124, supporting the standard cosmological model and providing
