Dissection of a merger-ringdown waveform in the small-mass-ratio limit
Patrick Bourg, Lorenzo Küchler, Benjamin Leather +6
Work over the past two decades has unveiled the rich phenomenology of black hole binary mergers and subsequent ringdowns, involving a tapestry of quasinormal modes (QNMs), nonlinea…
Not All Resonances Are Created Equal: Prioritizing Tidal Resonances in EMRIs
Béatrice Bonga, Patrick Bourg, Bram ten Brink +2
Tidal perturbations from nearby compact objects can drive resonant "kicks" in extreme-mass-ratio inspirals (EMRIs), imprinting potentially detectable phase shifts in LISA-band grav…
Quadratic quasinormal modes at null infinity on a Schwarzschild spacetime
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
The ringdown of perturbed black holes has been studied since the 1970s, but until recently, studies have focused on linear perturbations. There is now burgeoning interest in nonlin…
Quadratic quasi-normal mode dependence on linear mode parity
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
Quasinormal modes (QNMs) uniquely describe the dominant piece of the gravitational-wave ringdown of postmerger black holes. While the linear QNM regime has been extensively studied…
Multi-domain spectral method for self-force calculations
Rodrigo Panosso Macedo, Patrick Bourg, Adam Pound +1
Second-order self-force calculations will be critical for modelling extreme-mass-ratio inspirals, and they are now known to have high accuracy even for binaries with mass ratios $\…
Simple, efficient method of calculating the Detweiler-Whiting singular field to very high order
Patrick Bourg, Adam Pound, Samuel D. Upton +1
Most self-force calculations rely, in one way or another, on representations of a particle's Detweiler- Whiting singular field. We present a simple method of calculating the singul…
