Consistency tests of the stability of fundamental couplings and unification scenarios
M. C. Ferreira, O. Frigola, C. J. A. P. Martins +2
We test the consistency of several independent astrophysical measurements of fundamental dimensionless constants. In particular, we compare direct measurements of the fine-structur…
Constraining fundamental physics with combined variations of fundamental constants
A. M. R. V. L. Monteiro, M. C. Ferreira, M. D. Julião +1
We discuss how existing astrophysical measurements of various combinations of the fine-structure constant , the proton-to-electron mass ratio and the proton gyromagnetic rat…
A test of unification towards the radio source PKS1413+135
M. C. Ferreira, M. D. Julião, C. J. A. P. Martins +1
We point out that existing astrophysical measurements of combinations of the fine-structure constant , the proton-to-electron mass ratio and the proton gyromagnetic ratio $g…
Constraints on the CMB temperature redshift dependence from SZ and distance measurements
A. Avgoustidis, G. Luzzi, C. J. A. P. Martins +1
The relation between redshift and the CMB temperature, is a key prediction of standard cosmology, but is violated in many non-standard models. Constraining po…
