An empirically constrained Covariant Modified Gravity: exact reconstruction of galactic rotation curves and lensing
Xavier Hérnandez, Sergio Mendoza, Sarahí Silva +1
We present a covariant modified gravity theory which reproduces all the galactic phenomenology usually attributed to dark matter in the low acceleration regime, including the flat…
Approaching the Dark Sector through a bounding curvature criterion
X. Hernandez, R. A. Sussman, L. Nasser
Understanding the observations of dynamical tracers and the trajectories of lensed photons at galactic scales within the context of General Relativity (GR), requires the introducti…
MONDian dynamical modeling of NGC 288 with
X. Hernandez, R. A. M. Cortes, R. Scarpa
NGC 288 is a diffuse Galactic globular cluster, it is remarkable in that its low density results in internal accelerations being below the critical MOND acceleration throug…
Theoretical lower limits on sizes of ultra faint dwarf galaxies from dynamical friction
X. Hernandez
Dwarf spheroidal galaxies are the smallest known stellar systems where under Newtonian interpretations, a significant amount of dark matter is required to explain observed kinemati…
A universal velocity dispersion profile for pressure supported systems: evidence for MONDian gravity across 7 orders of magnitude in mass
R. Durazo, X. Hernandez, B. Cervantes Sodi +1
For any MONDian extended theory of gravity where the rotation curves of spiral galaxies are explained through a change in physics rather than the hypothesis of dark matter, a gener…
Gravitational anomalies signaling the breakdown of classical gravity
X. Hernandez, A. Jimenez, C. Allen
Recent observations for three types of astrophysical systems severely challenge the GR plus dark matter scenario, showing a phenomenology which is what modified gravity theories pr…
