These animations display the imprint that homogeneous but anisotropic Bianchi models induce in the cosmic microwave background (CMB).
scalars_movie.mp4 : Bianchi VIIh/VII0 scalar modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)
vectors_movie.mp4: Bianchi VIIh/VII0 vector modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)
tensor_movie.mp4: Bianchi VIIh/VII0 regular tensor modes, imprint on the CMB for varying morphology parameters (matter and dark-energy density, rotation scale of shear principal axes)
Additional fixed parameters for the three animations above:
cold-dark-matter physical density: 0.112
baryon physical density: 0.226
Pattern orientation additionally fixed to put spiral in full view

SVTT_movie.mp4: combinations of Bianchi VIIh/VII0 scalar, vector, regular and irregular tensor modes for varying relative amplitudes of these degrees of freedom and phase angle.
Additional fixed parameters:
cold-dark-matter physical density: 0.112
baryon physical density 0.0226
matter density: 0.27
dark energy density: 0.7
rotation scale of shear principal axes: 0.5
Pattern orientation additionally fixed to put spiral in full view
