Resumming Kerr Quasinormal-Mode Frequencies: Accuracy and Breakdown Near Extremality
Jierui Hu, Kent Yagi, Nicolas Yunes
The paper applies Padé and Borel‑Padé resummation to high‑order WKB expansions to compute Kerr black‑hole quasinormal‑mode frequencies, achieving very high accuracy for moderate sp…
Gravitational waves of quasi-circular, inspiraling black hole binaries in an ultralight vector dark-matter environment
Tomás Ferreira Chase, Diana López Nacir, Nicolás Yunes
The gravitational waves emitted by massive black hole binaries can be affected by a variety of environmental effects, which, if detected, could inform astrophysics and cosmology. W…
Constraining dark-sector effects using gravitational waves from compact binary inspirals
Caroline B. Owen, Alexandria Tucker, Yonatan Kahn +1
Gravitational wave observations are a powerful tool to constrain fundamental physics. This work considers dark matter that carries charge under a dark abelian massive vector field.…
Systematic biases due to waveform mismodeling in parametrized post-Einsteinian tests of general relativity: The impact of neglecting spin precession and higher modes
Rohit S. Chandramouli, Kaitlyn Prokup, Emanuele Berti +1
We study the robustness of parametrized post-Einsteinian (ppE) tests of General Relativity (GR) with gravitational waves, due to waveform inaccuracy. In particular, we determine th…
Possible Causes of False General Relativity Violations in Gravitational Wave Observations
Anuradha Gupta, K. G. Arun, Enrico Barausse +40
General relativity (GR) has proven to be a highly successful theory of gravity since its inception. The theory has thrivingly passed numerous experimental tests, predominantly in w…
Better early than never: A new test for superluminal gravitational wave polarizations
Kristen Schumacher, Colm Talbot, Daniel E. Holz +1
In some beyond-Einstein theories of gravity, gravitational waves can contain up to six polarizations, which are allowed to propagate at different speeds faster than light. These di…
