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 <math altimg="si1.svg"><mi>σ</...
