A time varying speed of light as a solution to cosmological puzzles
Andreas Albrecht, Joao Magueijo
We consider the cosmological implications of light travelling faster in the early Universe. We propose a prescription for deriving corrections to the cosmological evolution equatio…
Reionization by active sources and its effects on the cosmic microwave background
Jochen Weller, Richard A. Battye, Andreas Albrecht
We investigate the possible effects of reionization by active sources on the cosmic microwave background. We concentrate on the sources themselves as the origin of reionization, ra…
A new statistic for picking out Non-Gaussianity in the CMB
Alex Lewin, Andreas Albrecht, Joao Magueijo
In this paper we propose a new statistic capable of detecting non-Gaussianity in the CMB. The statistic is defined in Fourier space, and therefore naturally separates angular scale…
What is the future of causal models of cosmic structure formation?
Andreas Albrecht
Recent research has severely constrained the standard ``defect'' models of cosmic structure formation. Here I discuss the nature of the problems with defect models, and place this…
