Primordial Non-Gaussianity in the Large-Scale Structure of the Universe
Figure 5
Fractional deviation from the Gaussian mass function as a function of the peak height . Different symbols refer to different redshifts as in Figure 4. The curves are the theoretical prediction (25) at with (solid) and (dotted). In the top panel, halos were identified using a spherical overdensity (SO) finder with a redshift-dependent overdensity threshold whereas, in the bottom panel, a Friends-of-Friends (FOF) finding algorithm with linking length was used.
