Nonmetricity formulation of general relativity and its scalar-tensor extension [PDF]

open access: yesPhysical Review D, 2018
Einstein's celebrated theory of gravitation can be presented in three forms: general relativity, teleparallel gravity, and the rarely considered before symmetric teleparallel gravity.

Curvature Dynamics in General Relativity

open access: yesUniverse, 2023
The equations of general relativity are recast in the form of a wave equation for the Weyl tensor. This allows reformulation of gravitational wave theory in terms of curvature waves, rather than metric waves.

Review of testing black hole candidates with electromagnetic radiation [PDF]

open access: yesIranian Journal of Physics Research, 2023
Astrophysical black holes are thought to be Kerr solution of general relativity but there is not yet observational evidence to prove them. One can study the emission of electromagnetic waves around them to test their geometry of space time.

What is General Relativity? [PDF]

open access: yes, 2017
General relativity is a set of physical and geometric principles, which lead to a set of (Einstein) field equations that determine the gravitational field, and to the geodesic equations that describe light propagation and the motion of particles on the ...

Tests of General Relativity with GW150914.

open access: yesPhysical Review Letters, 2016
The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to witness the final merger of the binary and the excitation of uniquely ...

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid

open access: yesPhysics Letters B, 2022
We establish the nonlocal generalization of the Israel-Stewart model for the relativistic causal thermodynamics of the cosmic fluid, which evolves in the homogeneous isotropic Universe.

A precise extragalactic test of General Relativity [PDF]

open access: yesScience, 2018
Testing General Relativity on galaxy scales Einstein's theory of gravity, General Relativity (GR), has been tested precisely within the Solar System. However, it has been difficult to test GR on the scale of an individual galaxy. Collett et al. exploited

Phenomenological aspects of black holes beyond general relativity [PDF]

open access: yesPhysical Review D, 2018
While singularities are inevitable in the classical theory of general relativity, it is commonly believed that they will not be present when quantum gravity effects are taken into account in a consistent framework.
