Hořava gravity at a Lifshitz point: A progress report

A Wang - International Journal of Modern Physics D, 2017 - World Scientific
Hořava's quantum gravity at a Lifshitz point is a theory intended to quantize gravity by using
traditional quantum field theories. To avoid Ostrogradsky's ghosts, a problem that has been …

Shadows and rings of the Kehagias-Sfetsos black hole surrounded by thin disk accretion

GP Li, KJ He - Journal of Cosmology and Astroparticle Physics, 2021 - iopscience.iop.org
In this paper, under the illumination of thin disk accretion, we have employed the ray-tracing
method to carefully investigate shadows and rings of the Kehagias-Sfetsos (KS) black hole …

[HTML][HTML] An overview of quasinormal modes in modified and extended gravity

F Moulin, A Barrau, K Martineau - Universe, 2019 - mdpi.com
As gravitational waves are now being nearly routinely measured with interferometers, the
question of using them to probe new physics becomes increasingly legitimate. In this article …

TP Sotiriou, M Visser… - Journal of High Energy …, 2009 - iopscience.iop.org
There has been a significant surge of interest in Hořava's model for 3+ 1 dimensional
quantum gravity, this model being based on anisotropic scaling at az= 3 Lifshitz point …

Cosmological test of dark energy parameterizations in Hořava–Lifshitz gravity

H Chaudhary, NU Molla, M Khurana, U Debnath… - The European Physical …, 2024 - Springer
In this work, we assume that the FLRW universe, which is filled with dark matter along with
dark energy, is in the framework of Hořava–Lifshitz (HL) gravity. The dark energy is …

Dark matter as integration constant in Hořava-Lifshitz gravity

S Mukohyama - Physical Review D—Particles, Fields, Gravitation, and …, 2009 - APS
In the nonrelativistic theory of gravitation recently proposed by Hořava, the Hamiltonian
constraint is not a local equation satisfied at each spatial point but an equation integrated …

Analytical quasinormal modes of spherically symmetric black holes in the eikonal regime

MS Churilova - The European Physical Journal C, 2019 - Springer
Quasinormal modes in the high frequency (eikonal) regime can be obtained analytically as
the Mashhoon–Will–Schiutz WKB formula is exact in this case. This regime is interesting …

Thermodynamics and classification of cosmological models in the Horava-Lifshitz theory of gravity

A Wang, Y Wu - Journal of Cosmology and Astroparticle Physics, 2009 - iopscience.iop.org
We study thermodynamics of cosmological models in the Horava-Lifshitz theory of gravity,
and systematically investigate the evolution of the universe filled with a perfect fluid that has …

Detailed balance in Hořava-Lifshitz gravity

G Calcagni - Physical Review D—Particles, Fields, Gravitation, and …, 2010 - APS
We study Hořava-Lifshitz gravity in the presence of a scalar field. When the detailed balance
condition is implemented, a new term in the gravitational sector is added in order to maintain …
