Parity Isospectrality of the Kerr--Newman--de Sitter Black Hole
Colin Weller, Dongjun Li, Pratik Wagle +2
Vacuum Kerr perturbations in general relativity have identical even- and odd-parity quasinormal frequencies. We establish this parity isospectrality for linear gravitoelectromagnet…
Analytic Metric for Rotating Black Holes in Higher-Derivative Gravity
Jierui Hu, Dongjun Li, Nicolás Yunes
We turn metric reconstruction into an analytic solver for rotating black holes in modified gravity, bypassing the direct solution of coupled field equations. As an example, in pari…
Chiral symmetry and black hole isospectrality
Colin Weller, Dongjun Li, Pratik Wagle +3
We prove that black-hole isospectrality between linearly independent solutions follows whenever radiative metric and matter perturbations are reconstructed from complex master vari…
Living on the Edge of Effective Field Theory: Near-Extremal Black Holes in Quadratic Gravity
Kelvin Ka-Ho Lam, Gary T. Horowitz, Nicolás Yunes
Near-extremal black holes can amplify higher-derivative corrections to general relativity, making them sharp probes of the perturbative control of gravitational effective field the…
Measuring a Black Hole's Area Immediately after Merger: A Direct-Wave Test of Hawking's Area Law
Adrian Ka-Wai Chung, Kelvin Ka-Ho Lam, Anna Liu +1
Black-hole area is the geometric variable behind horizon thermodynamics. We introduce a gravitational-wave method to infer a Kerr-equivalent horizon area from direct waves in the n…
Cosmology of Gravi-Axions
Stephon Alexander, Gregory Gabadadze, Leah Jenks +1
We show how a mass term for gravitational axions (''gravi-axions'') with a Chern-Simons coupling to gravity can naturally arise due to non-perturbative contributions from Euclidean…
