Ringing of rapidly rotating black holes in effective field theory
Tom van der Steen, Simon Maenaut, Stef J. B. Husken +5
Within the effective field theory approach to gravity, deviations from general relativity can be systematically described by higher-curvature operators. However, computing the resu…

Quadratic gravity corrections to scalar QNMs of rapidly rotating black holes
Stef J. B. Husken, Tom van der Steen, Simon Maenaut +6
In an effective-field-theory framework for gravity, black-hole quasinormal mode spectra acquire corrections in quadratic-curvature, scalar-tensor extensions of general relativity.…

Good things always come in 3s: trimodality in the binary black-hole chirp-mass distribution supports bimodal black-hole formation
Reinhold Willcox, Fabian R. N. Schneider, Eva Laplace +7
The latest GWTC-4 release from the LIGO-Virgo-KAGRA (LVK) collaboration nearly doubles the known population of double compact object mergers and reveals a new trimodal structure in…
