Future mmVLBI Research with ALMA: A European vision

R. P. J. Tilanus, T. P. Krichbaum, J. A. Zensus +165

Very long baseline interferometry at millimetre/submillimetre wavelengths (mmVLBI) offers the highest achievable spatial resolution at any wavelength in astronomy. The anticipated…

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…

Probing Unification Scenarios with Atomic Clocks

M. D. Julião, M. C. Ferreira, C. J. A. P. Martins +1

We make use of the comparison between measurements of various pairs of atomic clocks to impose constraints on coupled variations of fundamental constants in severs unification scen…

Fundamental Cosmology in the E-ELT Era

C. J. A. P. Martins, M. C. Ferreira, M. D. Julião +4

The recent observational evidence for the acceleration of the universe demonstrates that canonical theories of cosmology and particle physics are incomplete - if not incorrect - an…

Probing unification scenarios with atomic clocks

M. C. Ferreira, M. D. Julião, C. J. A. P. Martins +1

We discuss the usage of measurements of the stability of nature's fundamental constants coming from comparisons between atomic clocks as a means to constrain coupled variations of…
