Cosmic distance-duality as probe of exotic physics and acceleration
Bruce A. Bassett, Martin Kunz
In cosmology, distances based on standard candles (e.g. supernovae) and standard rulers (e.g. baryon oscillations) agree as long as three conditions are met: (1) photon number is c…
Cosmic acceleration vs axion-photon mixing
Bruce A. Bassett, Martin Kunz
Axion-photon mixing has been proposed as an alternative to acceleration as the explanation for supernovae dimming. We point out that the loss of photons due to this mixing will ind…
Floquet analysis of disk instabilities and superhumps in Cataclysmic Variables
Fabrizio Tamburini, Bruce Bassett, Antonio Bianchini +1
The paper has been deeply reviewed and compeltely re-written.
Radiative constraints on brane quintessence
David Seery, Bruce A. Bassett
We investigate the constraints on quintessence arising from both renormalisable and non-renormalisable couplings where the 5d Planck mass is around the TeV scale. The quintessence…
Mapping the Dark Energy with Varying Alpha
David Parkinson, Bruce A. Bassett, John D. Barrow
Cosmological dark energy is a natural source of variation of the fine structure constant. Using a model-independent approach we show that once general assumptions about the alpha-v…
Application of the Separate Universe Approach to Preheating
Takahiro Tanaka, Bruce Bassett
The dynamics of preheating after inflation has not been clearly understood yet.In particular, the issue of the generation of metric perturbations during preheating on super-horizon…
Aspects of String-Gas Cosmology at Finite Temperature
Bruce A. Bassett, Monica Borunda, Marco Serone +1
We study string-gas cosmology in dilaton gravity, inspired by the fact that it naturally arises in a string theory context. Our main interest is the thermodynamical treatment of th…
