Temperature and Polarization Patterns in Anisotropic Cosmologies

Understand

We study the coherent temperature and polarization patterns produced in homogeneous but anisotropic cosmological models.

• We show results for all Bianchi types with a Friedman-Robertson-Walker limit (i.e.
• Types I, V, VII$_{0}$, VII$_{h}$ and IX) to illustrate the range of possible behaviour.
• We discuss the role of spatial curvature, shear and rotation in the geodesic equations for each model and establish some basic results concerning the symmetries of the patterns produced.
