Evidence for Galaxy dynamics tracing background cosmology below the de Sitter scale of acceleration.

Abstract (from CDS):
Galaxy dynamics probe weak gravity at accelerations below the de Sitter scale of acceleration adS=cH, where c is the velocity of light and H is the Hubble parameter. Low- and high-redshift galaxies hereby offer a novel probe of weak gravity in an evolving cosmology, satisfying H(z)=H0sqrt(1+ωm(6z+12z2+12z3+6z4+(6/5)z5))/(1+z) with matter content ωm=0.2808±0.028 sans tension to H0 in surveys of the local universe. Galaxy rotation curves show anomalous galaxy dynamics in weak gravity aN adS across a transition radius rt=4.7 kpc M111/2(H0/H)12 in galaxies of mass M=1011 M☉M11, where aN is the Newtonian acceleration based on baryonic matter content. We identify this behavior with a holographic origin of inertia from entanglement entropy, which introduces a C0 onset across aN=adS with asymptotic behavior described by a Milgrom parameter satisfying a0=ω0/2π, where ω0=sqrt(1-q)H is a fundamental eigenfrequency of the cosmological horizon. Extending an earlier confrontation with data covering 0.003 aN/adS 1 at redshift z∼0 in Lellie et al., the modest anomalous behavior in the Genzel et al. sample at redshifts 0.854 z 2.282 is found to be mostly due to clustering 0.36 aN/adS 1 close to the C0 onset to weak gravity and an increase of up to 65% in a0.
