Testing general relativity in cosmology [PDF]
Living Reviews in Relativity, 2018 We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

Carroll Expansion of General Relativity [PDF]
SciPost Physics, 2022 We study the small speed of light expansion of general relativity, utilizing the modern perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll limit, in which light cones close up. To this end, we first rewrite the

Landauer Principle and General Relativity [PDF]
Entropy, 2020 We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation.

Coincident general relativity [PDF]
Physical Review D, 2017 The Palatini's device is applied to generate teleparallel and symmetric teleparallel theories of gravity. From the latter is discovered an exceptional class which is consistent with a vanishing affine connection.

Hamiltonian formulation of general relativity and post-Newtonian dynamics of compact binaries. [PDF]
Living Rev Relativ, 2018 Hamiltonian formalisms provide powerful tools for the computation of approximate analytic solutions of the Einstein field equations. The post-Newtonian computations of the explicit analytic dynamics and motion of compact binaries are discussed within the

A HERO for General Relativity [PDF]
Universe, 2019 HERO (Highly Eccentric Relativity Orbiter) is a space-based mission concept aimed to perform several tests of post-Newtonian gravity around the Earth with a preferably drag-free spacecraft moving along a highly elliptical path fixed in its plane ...

Decoupling gravitational sources in general relativity: From perfect to anisotropic fluids [PDF]
Physical Review D, 2017 We show the first simple, systematic and direct approach to decoupling gravitational sources in general relativity. As a direct application, a robust and simple way to generate anisotropic solutions for self-gravitating systems from perfect fluid ...

Quantum Gravity in Everyday Life: General Relativity as an Effective Field Theory
Living Reviews in Relativity, 2004 This article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of general relativity as a theory from which precise ...

Microscopic Origin of the Entropy of Black Holes in General Relativity [PDF]
Physical Review X, 2022 We construct an infinite family of microstates with geometric interiors for eternal black holes in general relativity with negative cosmological constant in any dimension.
