Aperture mass peak counts for f(R) with fR0 = −10−5 and a varying sum of neutrino masses mν. Data points represent the mean over 256 realisations of each simulated cosmology and are plotted at scales (ϑ1, …, ϑ7 = 0.293′, 0.586′, 1.17′, 2.34′, 4.69′, 9.34′, 18.8′). The abundance of peaks above a 3σ threshold is shown in the left panel, and above a 5σ threshold in the right panel. An order of magnitude more peaks are detected at each scale with the lower threshold, although deviations from ΛCDM, as well as among the different mν cases of f5(R), are more pronounced with the higher threshold. This indicates that differences between models at this redshift are mostly contained in the highest amplitude peaks. Compared to the Map moments, peak counts interestingly do not very well distinguish between models with different neutrino mass, but they do distinguish modified from standard gravity, at least at certain scales.
