Multipole invariants and non-Gaussianity
Kate Land, Joao Magueijo
We propose a framework for separating the information contained in the CMB multipoles, , into its algebraically independent components. Thus we cleanly separate informa…
Bouncing Universes with Varying Constants
John D. Barrow, Dagny Kimberly, Joao Magueijo
We investigate the behaviour of exact closed bouncing Friedmann universes in theories with varying constants. We show that the simplest BSBM varying-alpha theory leads to a bouncin…
Cubic anomalies in WMAP
Kate Land, Joao Magueijo
We perform a frequentist analysis of the bispectrum of WMAP first year data. We find clear signal domination up to l=200, with overall consistency with Gaussianity except for the f…
String theories with deformed energy momentum relations, and a possible non-tachyonic bosonic string
Joao Magueijo, Lee Smolin
We consider a prescription for introducing deformed dispersion relations in the bosonic string action. We find that in a subset of such theories it remains true that the embedding…
