abstract

This article provides a detailed investigation into the motion of the surrounding particles around a polymer black hole in loop quantum gravity (LQG). Using effective potential, the critical bound orbits and innermost stable circular orbits (ISCO) are analyzed. The study finds that the radii and angular momentum of the critical bound orbits decrease with an increase in the parameter $A_\lambda$ which labels the LQG effects, while the energy and angular momentum of the ISCO also decreases with an increase in $A_\lambda$. Based on these findings, we then explore the periodic orbits of the polymer black hole in LQG using rational numbers composed of three integers. Our results show that the rational numbers increase with the energy of particles and decrease with the increase of angular momentum based on a classification scheme. Moreover, compared to a Schwarzschild black hole, the periodic orbits in a polymer black hole in LQG consistently have lower energy, providing a potential method for distinguishing a polymer black hole in LQG from a Schwarzschild black hole. Finally, we also examine the gravitational wave radiations of the periodic orbits of a test object which orbits a supermassive polymer black hole in LQG, which generates intricate GW waveforms that can aid in exhibiting the gravitational structure of the system.

  1. Eccentricity-Modulated Phase Degeneracy and Distinguishability between Dark Matter and Accretion Disk Environmental Effects in EMRIs

    gr-qc 2026-07 conditional novelty 5.5 of 10

    DM dephasing in EMRIs is nearly eccentricity-independent while disk dephasing is strongly suppressed by e0, so residual SNR and distinguishability time favor slightly eccentric orbits for LISA separation of the two effects.

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Keeping the nonareal polymer angular sector in a polymer-quintessence thin-shell wormhole adds a momentum-flux term that reshapes stability, thermodynamics, and cross-throat image branches.

  3. Rational Orbits and Gravitational Waves in Static Spherical Spacetimes: An Open-Source Numerical Framework

    gr-qc 2026-06 conditional novelty 5.0 of 10

    Open-source numerical package for rational orbits and gravitational waves in static spherically symmetric spacetimes, validated on Schwarzschild and applied to an IMBH-Sgr A* EMRI.

    gr-qc 2026-02 reject novelty 4.0 of 10

    A toy model shows that adding a hand-made angle-dependent force to dark-matter spacetimes produces visual chaos and irregular numerical-Kludge waveforms, but the force is not a realistic dark-matter perturbation.

    gr-qc 2025-07 conditional novelty 4.0 of 10

    A new time-frequency consistency test, built by stacking pixel energies along scaled orbital frequency tracks, flags deviations from General Relativity in injections and in GW190814 when higher modes are omitted.

    gr-qc 2025-02 conditional novelty 4.0 of 10

    A Hernquist-like dark matter halo changes the energies, angular momenta, and gravitational waveforms of periodic orbits around a supermassive black hole, compared with vacuum Schwarzschild.

  9. Polymer Black Hole Surrounded by Quintessence

    gr-qc 2025-07 conditional novelty 3.0 of 10

    A polymer black hole with quintessence yields a shadow that can match Sgr A* for many combinations of free parameters while cooling and dimming the black hole.
