Example convergence fields (top row) extracted from the three f5(R) simulations with neutrino mass sums of 0 eV, 0.1 eV, and 0.15 eV. Each map shows the same line of sight for sources at redshift zs = 2.0. Essentially the same structures are seen across all three maps due to identical initial conditions and the common field of view. Subtle differences, however, due to the different model evolutions can also be detected in the peak positions and their morphologies. Aperture mass residuals (bottom row) with respect to the ΛCDM map (not shown) at filtering scale ϑ3 = 1.17′ are shown for each corresponding map above. The compensated starlet filter has the effect of highlighting features with an approximate size of ϑ3. Our aim is to distinguish between these models using differences in the statistics of such aperture mass maps computed at different scales.
