Non-Gaussian Spectra
Pedro G. Ferreira, Joao Magueijo
Gaussian cosmic microwave background skies are fully specified by the power spectrum. The conventional method of characterizing non-Gaussian skies is to evaluate higher order momen…
Ideal scales for weighing the Universe
Joao Magueijo, M. P. Hobson
We investigate the performance of a large class of cosmic microwave background experiments with respect to their ability to measure various cosmological parameters. We pay special…
The Doppler peaks from a generic defect
Joao Magueijo
We investigate which of the exotic Doppler peak features found for textures and cosmic strings are generic novelties pertaining to defects. We find that the ``out of phase'' textur…
The structure of Doppler peaks induced by active perturbations
Joao Magueijo, Andreas Albrecht, Pedro Ferreira +1
We investigate how the qualitative structure of Doppler peaks in the angular power spectrum of the cosmic microwave anisotropy is affected by basic assumptions going into theories…
Observability of secondary Doppler peaks in the CMBR power spectrum by experiments with small fields
M. P. Hobson, Joao Magueijo
We investigate the effects of finite sky coverage on the spectral resolution in the estimation of the CMBR angular power spectrum . A method is developed for obta…
