Recently, we have extended the X-ray reflection model relxill to test the spacetime metric in the strong gravitational field of astrophysical black holes. In the present Letter, we employ this extended model to analyze XMM-Newton, NuSTAR, and Swift data of the supermassive black hole in 1H0707-495 and test deviations from a Kerr metric parametrized by the Johannsen deformation parameter $\alpha_{13}$. Our results are consistent with the hypothesis that the spacetime metric around the black hole in 1H0707-495 is described by the Kerr solution.

  1. A Space Mission to Earth's Nearest Black Hole: Reality or Science Fiction?

    gr-qc 2026-07 conditional novelty 4.0

    An interstellar nanocraft mission to a nearby black hole is technologically speculative but potentially feasible within decades and could deliver precision strong-field tests of General Relativity.

  2. Testing black hole metrics with binary black hole inspirals

    gr-qc 2025-10 unverdicted novelty 3.0

    Constraints on deviations from Kerr black hole metrics are derived from binary black hole inspiral waveforms modeled with effective one-body methods and analyzed via the parameterized post-Einsteinian framework.

  3. Physics and Astrophysics of Black Holes with eXTP

    astro-ph.HE 2026-07 accept novelty 2.0

    eXTP’s larger effective area and simultaneous polarimetry will tighten black-hole spin and Kerr-deviation constraints relative to NICER for the same exposure.
