Non-Gaussianity in the Squeezed Three-Point Correlation from the Relativistic Effects
Jaiyul Yoo, Nastassia Grimm, Ermis Mitsou
Assuming a LCDM universe in a single-field inflationary scenario, we compute the three-point correlation function of the observed matter density fluctuation in the squeezed triangu…
