Frame covariance of CMBR lensing in the exact 1+3 covariant radiation hierarchy
Tim Gebbie
The exact covariant Boltzmann hierarchy for the cosmic microwave background contains acceleration, shear and vorticity couplings whose coefficients grow linearly in . W…
The Limits on Cosmological Anisotropies and Inhomogeneities from COBE Data
William Stoeger, Marcelo Araujo, Tim Gebbie
Assuming that the cosmological principle holds, Maartens, Ellis and Stoeger (MES) recently constructed a detailed scheme linking anisotropies in the cosmic background radiation (CM…
1+3 Covariant Cosmic Microwave Background anisotropies II: The almost - Friedmann Lemaitre model
Tim Gebbie, Peter Dunsby, George Ellis
This is the second of a series of papers extending the 1+3 covariant and gauge invariant treatment of kinetic theory to an examination of Cosmic Microwave Background temperature an…
Cosmic microwave background anisotropies: Nonlinear dynamics
Roy Maartens, Tim Gebbie, George Ellis
We develop a new approach to local nonlinear effects in cosmic microwave background anisotropies, and discuss the qualitative features of these effects. New couplings of the baryon…
1+3 Covariant Cosmic Microwave Background anisotropies I: Algebraic relations for mode and multipole representations
Tim Gebbie, George F. R. Ellis
This is the first of a series of papers extending a covariant and gauge invariant (CGI) treatment of kinetic theory in curved space-times to a treatment of Cosmic Background Radiat…
