abstract

In this paper, we investigate the impact of loop quantum gravity (LQG) on extreme mass-ratio inspirals (EMRIs), and the results indicate that LQG effects cause the orbital decay to occur faster compared to the Schwarzschild case. Furthermore, we use the augmented analytic kludge approach to generate EMRI waveforms and study the LISA's capability to detect the LQG effect with faithfulness. Additionally, employing the Fisher information matrix method for parameter estimation, we estimate that after one year of observation, the uncertainty in $r_0$ reduces to approximately $6.59\times 10^{-4}$ with a signal-to-noise ratio of $49$.

  1. Extreme mass-ratio inspirals and extra dimensions: Insights from modified Teukolsky framework

    gr-qc 2025-07 conditional novelty 5.0 of 10

    A modified Teukolsky equation and the Dudley-Finley approximation give nearly the same LISA detectability bound for the braneworld tidal charge, with MTE mismatches growing faster for high-eccentricity EMRIs.

  2. Shadow constraints of charged black hole with scalar hair and gravitational waves from extreme mass ratio inspirals

    gr-qc 2025-06 conditional novelty 5.0 of 10

    EHT shadow data constrain the EMCS black hole charge and scalar hair to about 0.1 and 0.01 levels, while LISA EMRI waveforms could reach 0.01 and 0.0001 levels.
