Density profiles (left column) and projected density contrasts (right column) of halos of different mass (color coded) at redshift z = 1 for different ULA particle masses (rows) in the extreme case of a ULA-only dark matter sector. Full lines show the total profiles, dashed lines show the corresponding cold dark matter profiles (assumed to follow a Navarro-Frenk-White profile), and dotted lines show the soliton core profile. In the right column, we highlight the scales we use for the weak lensing measurement in white.
