Comment on `An extreme critical spacetime: echoing and black-hole perturbations'
Open accessAbstract
We show that the black hole perturbations of the Hayward static solution to the massless Einstein-Klein-Gordon equations are actually gauge artifacts resulting from the linearization of a coordinate transformation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The ω_B modes are spurious, artifacts arising from the linearization of a coordinate transformation, and only the ω_A modes correspond to physical perturbations.
“However, it was later clarified in [287] that the ω B modes are spurious, artifacts arising from the linearization of a coordinate transformation, and only the ω A modes correspond to physical perturbations.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
