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.

$D$ -dimensional aether charged black hole and aether waves in M-subset of Einstein-aether theory

This paper investigates $D$ -dimensional charged black hole solutions and gravitational wave polarizations within a specific M-subset of Einstein-aether theory, revealing a unique aether charge constraint, exact thermodynamic laws, and distinct wave propagation characteristics where spin-2 and spin-1 modes travel at unit speed while the longitudinal mode exhibits linear time dependence rather than behaving as a spin-0 mode.

Geodesic dynamics and multi-inclination images of a non-minimally coupled black hole with a thin accretion disk

This paper investigates the optical properties of a non-minimally coupled Einstein-Yang-Mills black hole with a thin accretion disk, revealing that the coupling parameter significantly alters the ISCO and photon sphere, extends the impact parameter range, enhances redshift, and ultimately produces a weaker observed intensity compared to Schwarzschild and Reissner-Nordström black holes across all inclination angles.

Quintessence-dominated cyclic universe with negative cosmological constant

This paper investigates two non-singular cyclic universe models driven by a negative, time-varying cosmological constant, demonstrating that they can achieve physically acceptable positive energy density evolution and specific dynamical features like pressure sign flipping or phantom divide crossing without violating the null energy condition.

Dynamical Dark Energy models in light of the latest observations

This paper analyzes various dynamical dark energy models against the latest cosmological observations (excluding SH0ES and structure formation data) and finds that the "flipped RVM," along with the $w$ XCDM and threshold RVM models, provides significant evidence for dynamical dark energy comparable to the $w_0w_a$ CDM parameterization, particularly when using DES-Y5 data.

Jet launching from the Kerr black hole magnetosphere: An electrogeodesic approach

This paper presents a fully analytical model of relativistic jet launching from a Kerr black hole's magnetosphere by utilizing the integrability of electrogeodesic motion to derive criteria for stable particle ejection, magnetic frame-dragging effects, and asymptotic blueshift conditions.

Holographic timelike entanglement and subregion complexity with scalar hair

This paper investigates holographic timelike entanglement entropy and subregion complexity in scalar-deformed thermal CFTs dual to hairy black holes, demonstrating that the scalar deformation breaks the imaginary component invariance of HTEE observed in pure AdS, reveals the failure of analytic continuation to reproduce these results, and establishes that timelike subregion complexity remains real-valued with its UV-finite term in BTZ geometry arising entirely from the black hole interior.

Complete asymptotics in the formation of quiescent big bang singularities

This paper unifies three major categories of mathematical results on quiescent big bang singularities by demonstrating that solutions satisfying recent general conditions for big bang formation indeed induce well-defined initial data on the singularity, thereby bridging the gap between stable formation proofs and geometric data construction.

A Unified Interpretation of Supernova, GRB, and QSO Time Dilation Signals in a Generalized Cosmological Time Framework

This paper proposes a Generalized Cosmological Time framework that resolves conflicting time dilation observations by distinguishing between discrete, gravitationally shielded transients (SNe Ia and GRBs) that exhibit geometric path dilation and persistent thermal sources (QSOs) whose signals are masked by intrinsic selection effects.

Electron-positron Pair Production in Global GRMHD Simulations of Black Hole Accretion Flows

This paper presents global 3D GRMHD simulations incorporating pair physics to reveal that electron-positron pairs in black hole accretion flows are primarily generated near the disk midplane and transported via advection to the corona and jets, where they can significantly exceed equilibrium values and potentially regulate coronal temperatures.

Meissner Effect in Kerr--Bertotti--Robinson Spacetime

This paper analytically proves the black-hole Meissner effect for extremal Kerr--Bertotti--Robinson spacetimes by demonstrating that horizon-threading magnetic flux vanishes in the static limit through exact identities derived from the horizon's double-root structure, a result corroborated by geometric arguments and contrasted with other spacetime families.
