Description
This work explores the viability of Hyperconical Modified Gravity (HMG) as a relativistic alternative to the Modified Newtonian Dynamics (MOND) in explaining the dynamics of galaxy clusters, radial accelerations and galaxy rotation curves. By using five datasets (including high-resolution X-ray data and weak-lensing observations), we test HMG's predictions for hydrostatic equilibrium in galaxy clusters and flat rotation curves in galaxies. Our results show that HMG successfully accounts for the observed dynamics in the analysed gravitational systems even beyond 500 kpc and reproduces flat rotation curves on scales of 1 Mpc, outperforming MOND in some cases. These findings suggest that HMG offers a promising framework for understanding gravitational anomalies without invoking dark matter, though further research is needed to refine the model and extend its applicability.
