Quantum gravity represents the frontier where the very large meets the very small, attempting to unify Einstein's theory of gravity with the strange rules of quantum mechanics. This field explores the fundamental fabric of spacetime, seeking to understand how the universe behaves at its most extreme scales, from the heart of black holes to the moment of the Big Bang. Because these concepts often involve complex mathematics, they can feel distant to non-specialists, yet they hold the key to a complete picture of physical reality.
At Gist.Science, we bridge this gap by processing every new preprint in this category directly from arXiv.

Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.
This paper investigates an acoustic black hole within Hayward spacetime derived from relativistic Gross-Pitaevskii theory, numerically analyzing its shadow, quasinormal modes, and analogue Hawking radiation to demonstrate how a tuning parameter enhances emission rates and shadow size while stabilizing oscillation frequencies through effective potential modifications.
This paper investigates the dynamical stability of stationary electrically charged Proca stars by performing numerical evolutions of perturbed configurations, revealing that their fate—ranging from stable equilibrium to collapse into a Reissner–Nordström black hole, migration to a stable branch, or dispersion to infinity—depends on the charge parameter and binding energy.
This paper investigates the analytical dynamics of spinning particles in pp-wave spacetimes, including plane gravitational and impulsive shockwaves, by utilizing specific spin supplementary conditions and Hamiltonian formalisms to establish a relationship between these motions and electromagnetic fields via gauge-gravity duality.
By analyzing the spatial and temporal correlation between 80 LIGO/Virgo/KAGRA binary black hole mergers and six years of Zwicky Transient Facility data, this study constrains the fraction of mergers associated with active galactic nucleus flares to , a result primarily driven by a single candidate counterpart to GW190412 that supports the active galactic nucleus disk formation channel.
This paper develops a formalism for calculating the finite, observer-dependent quantum effective potential in dimensional Euclidean Rindler space and applies it to demonstrate the restoration of spontaneously broken symmetry in three and four dimensions.
This paper investigates the quasinormal modes of tensor perturbations in Maeda-Dadhich Kaluza-Klein black holes within Einstein-Gauss-Bonnet gravity, utilizing the asymptotic iteration and numerical integration methods to reveal how six specific parameters influence the frequencies while finding that the dimension of the compactified space has no significant impact on the modes' lifetime.
This paper introduces a new, fully analytic weak-signal approximation of the Bayes factor for continuous gravitational waves that, by modeling the amplitude prior as a half-Gaussian distribution, achieves computational efficiency comparable to the -statistic while demonstrating state-of-the-art or improved sensitivity across a wide range of coherent and semi-coherent search segment lengths.
Using worldline quantum field theory and modern diagrammatic techniques, this paper derives spinning black hole scattering trajectories up to quadratic order in spins and establishes a new framework for computing radiated angular momentum up to 2PM order, thereby advancing high-precision analytical gravitational wave physics.
This paper investigates the accretion of a collisionless relativistic gas by a rotating Kerr black hole, deriving closed integral expressions for physical observables and demonstrating that while black hole rotation significantly reduces the angular momentum accretion rate, it exerts a smaller, analytically predictable influence on mass and energy accretion rates.
This paper derives an exact kinetic solution for stationary Bondi-type accretion onto a Kerr black hole, providing explicit formulas for mass, energy, and angular momentum accretion rates to analyze black hole growth and spin-down under constant or cosmologically decreasing ambient energy densities.
