gr-qc papers | Gist.Science

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. Our team provides both plain-language explanations and detailed technical summaries for each paper, ensuring that groundbreaking research is accessible to everyone, from curious students to seasoned researchers. Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.

Relativistic Tidal Dissipation and the Gravitational-wave Signal of a White Dwarf Orbiting an Intermediate-Mass Black Hole

This paper presents a fully relativistic model demonstrating that tidal dissipation in white dwarf–intermediate-mass black hole binaries significantly suppresses orbital energy loss, accelerates eccentricity damping, and induces measurable deviations in gravitational wave signals, thereby offering a crucial framework for understanding multi-messenger observations of these systems.

Universality of the Blandford-Znajek emission in stationary and axisymmetric spacetimes

This paper demonstrates that while the lowest-order Blandford-Znajek jet power is universal across generic stationary and axisymmetric black-hole spacetimes, the next-leading-order corrections depend on the specific spacetime geometry, offering a potential method to distinguish rapidly rotating black holes through combined measurements of jet luminosity and angular velocity.

Polarisation Singularities of Gravitational Waves

This paper extends the theory of polarisation singularities to gravitational waves and higher spin fields, demonstrating that these geometric structures are generic features of wave interference whose dimensionality depends on the field's spin.

OmegaNeuron: Applying GravitySpy Similarity Methods to the Search for LIGO Glitch Witnesses

This paper introduces OmegaNeuron, a machine-learning tool integrated into the gwdetchar package that automates the identification of LIGO glitch witnesses by combining GravitySpy's image similarity methods with Omega Scan's transient analysis to improve detector sensitivity and observation reliability.

Scalar Bosons with Coulomb Potentials in a Space with Dual Topological Defects in Rainbow Gravity

This paper investigates the relativistic quantum dynamics of scalar bosons subject to Coulomb-type potentials in a spacetime featuring both cosmic string and global monopole defects within the framework of Rainbow Gravity, deriving bound-state energy spectra that reveal the interplay between topological defects and energy-dependent spacetime deformations.

Mimetic gravity in the extended objects framework

This paper introduces Lovelock-type brane gravity (LBG) as a second-order extension of geodetic brane gravity within an elasticity framework, demonstrating how it can be reformulated as mimetic embedding gravity where a fictional current generates an effective energy-momentum tensor with perfect fluid characteristics.

Realistic Equations of State Informing Neutron Star Post-Merger Gravitational-Wave Frequencies

By employing realistic relativistic mean field equations of state with consistent thermal treatments, this study demonstrates that post-merger gravitational-wave peak frequencies span 2.5 to 4 kHz, thereby highlighting the necessity for broadband observatories with kilohertz sensitivity and validating the KAGRA high-frequency design over its broadband counterpart.

Photon rings, gravitational lensing, and ISCOs of exotic compact objects in Einstein-scalar-Maxwell theories

This paper investigates the properties and observational signatures of electrically charged exotic compact objects in Einstein-scalar-Maxwell theories, demonstrating their shell-like structure and establishing constraints on model parameters by analyzing photon rings, gravitational lensing, and innermost stable circular orbits.

A 3BF model of quantum gravity coupled to Standard Model matter

This paper presents a rigorous 3BF model of quantum gravity coupled to Standard Model matter within higher gauge theory, achieved by discretizing the action and path integral on a piecewise-flat spacetime manifold to enable a well-defined quantum formulation and preliminary semiclassical analysis.

Acoustic Black Hole in Hayward Spacetime: Shadow, Quasinormal Modes and Analogue Hawking Radiation

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.
