Primordial Non-Gaussianity and Bispectrum Measurements in the Cosmic Microwave Background and Large-Scale Structure

Figure 23

(a) Range of scales probed by different observables compared with for different values of the running parameter , from the study by Lo Verde et al. in [137]. (b) Predictions of DBI models showing the peculiar relation between the amplitude and the running for different values of the parameters of the inflaton Lagrangian. The figure includes the Fisher matrix forecasts for combined CMB and galaxy bispectrum measurements assuming a fiducial , from the study by Sefusatti et al. in [87]; see the reference for further details.
