This investigation aims to understand the physical basis of the galaxy acceleration scale and its implication across redshifts.
Analyzed 149 galaxies with 3152 data points using hierarchical fitting methods.
Developed a parameter-free law to describe effective gravitational dynamics.
Utilized environmental fields from catalogs to compare with galaxy behavior and rotation curves.
The model predicts the local acceleration scale with high accuracy and reproduces rotation curves without free parameters.
Evidence suggests a galaxy-to-galaxy variation in dynamics, supporting the hypothesis of environmental influences.
Additional observations indicate a need for further explorations of the predicted evolution of acceleration relationships.
