Cosmic microwave background temperature cosmography
C. J. A. P. Martins
The temperature-redshift relation, , is a cornerstone of the standard cosmological model, but it is violated in many physically motivated extensions thereof, e.g. wh…
Varying fundamental constants cosmography
C. J. A. P. Martins
Cosmography is a model-independent phenomenological approach to observational cosmology, relying on Taylor series expansions of physical quantities as a function of the cosmologica…
Current and future cosmological impact of microwave background temperature measurements
C. J. A. P. Martins, A. M. M. Vieira
The redshift dependence of the cosmic microwave background temperature, , is a key prediction of standard cosmology, but this relation is violated in many extensions…
Cosmic Microwave Background Signatures from Current-carrying Cosmic Strings
I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter +1
We continue our studies of the evolution and cosmological consequences of current-carrying cosmic string networks, described by a charge-velocity-dependent one scale (CVOS) model.…
Cosmology and fundamental physics with the ELT-ANDES spectrograph
C. J. A. P. Martins, R. Cooke, J. Liske +20
State-of-the-art 19th century spectroscopy led to the discovery of quantum mechanics, and 20th century spectroscopy led to the confirmation of quantum electrodynamics. State-of-the…
News from the Swampland -- Constraining string theory with astrophysics and cosmology
Nils Schöneberg, Léo Vacher, J. D. F. Dias +2
Our current best guess for a unified theory of gravitation and quantum field theory (string theory) generically predicts a set of requirements for a consistently quantized theory,…
