Remarkable small difference between galaxy luminosity distances due to dynamic dark energy. Distances are ratioed to static dark energy (the green line). The red curve is the cosmology of Abdul Karim et al. (2025). Its turnaround is due to matter domination for z > 1. The points are for DM mass loss with Ω_m′ = 0.015. They do not turn around because Ω_m′ is still effective at z > 1. That could be remedied by suitable choice of a PBH IMF.
