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

Black Holes in an Effective Field Theory Extension of General Relativity. [PDF]
Physical Review Letters, 2018 Effective field theory methods suggest that some rather general extensions of general relativity include, or are mimicked by, certain higher-order curvature corrections, with coupling constants expected to be small but otherwise arbitrary.

Curvature Dynamics in General Relativity
Universe, 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.

Global Monopole in General Relativity [PDF]
, 2002 We consider the gravitational properties of a global monopole on the basis of the simplest Higgs scalar triplet model in general relativity. We begin with establishing some common features of hedgehog-type solutions with a regular center, independent of ...

Dipolar Particles in General Relativity [PDF]
, 2006 The dynamics of "dipolar particles", i.e. particles endowed with a four-vector mass dipole moment, is investigated using an action principle in general relativity. The action is a specific functional of the particle's world line, and of the dipole moment

A precise extragalactic test of General Relativity [PDF]
Science, 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

Non-linear obstructions for consistent new general relativity [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We revisit the field content and consistency of the New General Relativity family of theories. These theories are constructed in a geometrical framework with a flat and metric-compatible connection, so the affine structure is entirely determined by the ...

Phenomenological aspects of black holes beyond general relativity [PDF]
Physical 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.
