Impact and measurability of linear relativistic effects in galaxy surveys
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Olivier Doré
The three-dimensional galaxy power spectrum is a powerful probe of primordial non-Gaussianity (PNG) and additional general relativistic (GR) effects on large scales, which can be c…
