Looking for a varying in the Cosmic Microwave Background
P. P. Avelino, C. J. A. P. Martins, G. Rocha +1
We perform a likelihood analysis of the recently released BOOMERanG and MAXIMA data, allowing for the possibility of a time-varying fine-structure constant. We find that in general…
Cosmology with Varying Constants
C. J. A. P. Martins
I motivate and discuss some recent work on theories with varying constants, and consider some possible observational consequences and tests. Particular emphasis is given to models…
Can we predict the fate of the Universe?
P. P. Avelino, J. P. M. de Carvalho, C. J. A. P. Martins
We re-analyze the question of the use of cosmological observations to infer the present state and future evolution of our patch of the universe. In particular, we discuss under whi…
VSL theories and the Doppler peak
P. P. Avelino, C. J. A. P. Martins, G. Rocha
We discuss constraints on so-called `varying speed of light theories' coming from the physics of the early universe. Specifically, we consider the position of the first acoustic pe…
