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…

Ringdown Analysis of Rotating Black Holes in Effective Field Theory Extensions of General Relativity
Simon Maenaut, Gregorio Carullo, Pablo A. Cano +4
Quasinormal modes of rapidly rotating black holes were recently computed in a generic effective-field-theory extension of general relativity with higher-derivative corrections. We…

Millilensing induced systematic biases in parameterized tests of General Relativity
Anna Liu, Rohit S. Chandramouli, Otto A. Hannuksela +2
Tests of general relativity (GR) can be systematically biased when our waveform models are inaccurate. We here study systematic biases in tests of general relativity induced by neg…
