A first linear cosmological structure formation scenario under extended gravity
X. Hernandez, M. A. Jimenez
The inability of primordial baryonic density fluctuations, as observed in the cosmic microwave background (CMB), to grow into the present day astronomical structures is well establ…
Isothermal distributions in MONDian gravity as a simple unifying explanation for the ubiquitous density profiles in tenuous stellar halos
X. Hernandez, M. A. Jimenez, C. Allen
That the stellar halo of the Milky Way has a density profile which to first approximation satisfies has been known for a long time. More recently, it has become c…
The massive elliptical galaxy NGC 4649 from the perspective of extended gravity
M. A. Jimenez, G. Garcia, X. Hernandez
Elliptical galaxies are systems where dark matter is usually less necessary to explain observed dynamics than in the case of spiral galaxies, however there are some instances where…
Flattened velocity dispersion profiles in Globular Clusters: Newtonian tides or modified gravity?
X. Hernandez, M. A. Jimenez, C. Allen
Over the past couple of years, a number of observational studies have confirmed the flattening of the radial velocity dispersion profiles for stars in various nearby globular clust…
Wide binaries as a critical test for Gravity theories
X. Hernandez, M. A. Jimenez, C. Allen
Assuming Newton's gravity and GR to be valid at all scales leads to the dark matter hypothesis as a requirement demanded by the observed dynamics and measured baryonic content at g…
Non-relativistic Extended Gravity and its applications across different astrophysical scales
J. C. Hidalgo, S. Mendoza, X. Hernandez +3
Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quan…
The outskirts of globular clusters as modified gravity probes
X. Hernandez, M. A. Jimenez
In the context of theories of gravity modified to account for the observed dynamics of galactic systems without the need to invoke the existence of dark matter, a prediction often…
Wide binaries as a critical test of Classical Gravity
X. Hernandez, M. A. Jimenez, C. Allen
Modified gravity scenarios where a change of regime appears at acceleration scales have been proposed. Since for systems the acceleration drops below $a_{0}…
