Probing inflationary gravitational waves with cross-correlations: improved forecasting and validation with simulations

Posted by dbos Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Irene Abril-Cabezas, Blake D. Sherwin, , | Summary: We present a follow-up study to the method recently proposed by Namikawa & Sherwin (2023) to probe gravitational waves using cross-correlations between two CMB $B$-modes and a large-scale structure tracer. We first improve on the previous forecast […]
