Constraining single-field inflation with MegaMapper
We forecast the constraints on single-field inflation from the bispectrum of future high-redshift surveys such as MegaMapper. Considering non-local primordial non-Gaussianity (NLPNG), we find that current methods will yield constraints of order σ(fNLeq)≈23, σ(fNLorth)≈12 in a joint power-spectrum an...
