SUMMARY

E and B mode polarizations are critical concepts in cosmology, specifically in the study of the Cosmic Microwave Background (CMB). E modes arise from scalar and tensor perturbations, while B modes are exclusively generated by tensor perturbations, such as gravitational waves. The distinction between these modes is essential for understanding temperature anisotropies, which represent variations in temperature across the CMB. For further reading, the resource provided by Berkeley's cosmology department offers valuable insights into these phenomena.

PREREQUISITES
  • Understanding of Cosmic Microwave Background (CMB) theory

Basically as the questions says, can anyone explain what E and B mode polarisations are and homework they differ from temp anisotropies.

I know that E mode are from scalar and tensor perturbations B mode from tensor perturbations (Gwaves). I don't really understand what they are or how they differ from the change in temp.

Any recommended literature would be helpful
