The Newtonian Fundamental Plane breaks down in the low-acceleration regime. A tight BFJR takes over.

Using ~1400 pressure-supported systems, the BFJR converges to M_bar ∝ σ⁴ around a₀. Consistent with MOND.

A tight mass-velocity dispersion relation (MVDR; black solid line) was found on the BCG-cluster scale, albeit at a larger acceleration scale. Moreover, MaNGA BCGs display almost flat velocity dispersion profiles, even in the innermost region.
