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 ...

Noncommutative General Relativity [PDF]
Physical Review D, 2005 We define a theory of noncommutative general relativity for canonical noncommutative spaces. We find a subclass of general coordinate transformations acting on canonical noncommutative spacetimes to be volume-preserving transformations.

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.

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

Numerical relativity simulation of GW150914 beyond general relativity [PDF]
Physical Review D, 2020 We produce the first astrophysically-relevant numerical binary black hole gravitational waveform in a higher-curvature theory of gravity beyond general relativity.

Galaxies, 2014 A brief account of the present status of the recent nonlocal generalization of Einstein’s theory of gravitation is presented. The main physical assumptions that underlie this theory are described.

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.

Unimodular gravity vs general relativity: a status report [PDF]
Classical and quantum gravity, 2022 Unimodular gravity (UG) is an alternative to general relativity (GR) which, however, is so closely related to the latter that one can wonder to what extent they are different.
