Imprints of Large-Scale Structures in the Anisotropies of the Cosmological Gravitational Wave Background We compute the cross-correlation between the anisotropies of the cosmological gravitational wave background (CGWB) and the galaxy density contrast. We show that the cross-correlation is non-zero due t...

From last week arXiv!
Check our new paper (with @rafalafelo.bsky.social) on how Cosmological Gravitational Waves could correlate with Large-Scale Structures, and its potential synergies with Primordial non-Gaussianity.
