Signatures of anisotropic sources in the trispectrum of the cosmic microwave background
Maresuke Shiraishi, Eiichiro Komatsu, Marco Peloso
Soft limits of -point correlation functions, in which one wavenumber is much smaller than the others, play a special role in constraining the physics of inflation. Anisotropic s…
