Disentangling Doppler modulation, aberration and the temperature dipole in the CMB
Pedro da Silveira Ferreira, Miguel Quartin
An observer in relative motion to the Cosmic Microwave Background (CMB) rest frame is sensitive to both aberration and Doppler effects. Both effects introduce similar but non-ident…
First constraints on the intrinsic CMB dipole and our velocity with Doppler and aberration
Pedro da Silveira Ferreira, Miguel Quartin
We test the usual hypothesis that the Cosmic Microwave Background (CMB) dipole, its largest anisotropy, is due to our peculiar velocity with respect to the Hubble flow by measuring…
How Anisotropic is our Universe?
Emory. F. Bunn, Pedro Ferreira, Joseph Silk
Large-scale cosmic microwave background anisotropies in homogeneous, globally anisotropic cosmologies are investigated. We perform a statistical analysis in which the four-year dat…
Causality, randomness, and the microwave background
Andreas Albrecht, David Coulson, Pedro Ferreira +1
Fluctuations in the cosmic microwave background (CMB) temperature are being studied with ever increasing precision. Two competing types of theories might describe the origins of th…
