Eventual flattening of velocity dispersion profiles of some galactic globular clusters (GCs) in the Milky Way cannot be explained in the framework of Newtonian gravity and hence in general theory of relativity in the weak field limit, without resorting to the occurrence of tidal effects. We explore the possibility of explaining such deviation from expected Keplerian fall-off in dispersion profiles within the context of Weyl conformal gravity. We choose a set of 20 GCs for which recent… Expand

Modified gravity theories in light of the anomalous velocity dispersion of NGC1052-DF2
Recent observations of ultra-dwarf galaxy NGC1052-DF2 started an interesting discussion between dark matter hypothesis and modified gravity theories. Reported low velocity dispersion (< 10.5 km/s atExpand
Late-time and Big Bang Nucleosynthesis constraints for generic modified gravity surveys
In this work, a new generic parameterisation for f ( R ) theories is presented. Our proposal for a new equation of state can reproduce an f ( R )-like evolution that describes late and early timeExpand
Testing gravity with the Milky Way: Yukawa potential
We test a Yukawa correction to the Newtonian potential, making use of our own Galaxy - the Milky Way - as a testbed. We include as free parameter the Yukawa strength and range and the dark matter NFWExpand
A `Third' Quantization Constructed for Gauge Theory of Gravity
In general, a global and unique vacuum state cannot be constructed for a curved space. As a remedy, we introduce a curved space background geometry with a Minkowski metric tensor and locally nonzeroExpand
A pr 2 02 1 Gravity as a ‘ Third ’ Quantization Gauge Theory with Minkowski Metric , Non-Zero Torsion and Curvature
It is understood that, in general, a global and unique vacuum state cannot be considered in a curved space. Hence, we have introduced a geometry that, in addition of having non-zero local curvatureExpand
Conformal Weyl gravity via two stages of quasinormal ringing and late-time behavior
Black hole (BH) solution in the conformal Weyl gravity is a generalization of the Schwarzschild spacetime which includes two additional constants appearing when integrating the third orderExpand
Enigmatic velocity dispersions of ultradiffuse galaxies in light of modified gravity theories and the radial acceleration relation
Recent observations of anomalous line-of-sight velocity dispersions of two ultra-diffuse galaxies (UDGs) provide a stringent test for modified gravity theories. While NGC 1052-DF2 exhibits anExpand


Flattened velocity dispersion profiles in Globular Clusters: Newtonian tides or modified gravity?
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 clusters. As theExpand
Using globular clusters to test gravity in the weak acceleration regime
We have carried out a study of the velocity dispersion of the stars in the outskirts of the globular cluster ω Cen, finding that the velocity dispersion remains constant at large radii rather thanExpand
X‐ray clusters of galaxies in conformal gravity
We run adiabatic N-body/hydrodynamical simulations of isolated self-gravitating gas clouds to test whether conformal gravity, an alternative theory to general relativity, is able to explain theExpand

Testing Weyl gravity at galactic and extra-galactic scales
We examine the viability of Weyl conformal gravity as an alternative to the general theory of relativity. By using the extended rotation curve of the Milky Way and velocity dispersions of fourExpand

Conformal gravity has a weak-field limit that augments the Newtonian potential -GM/R by a linear potential γc 2 R/2. Mannheim has shown that an appropriate choice of y enables a satisfying fit to theExpand
