Asymptotic flatness beyond General Relativity
David Maibach
The asymptotic symmetry group of asymptotically flat spacetimes gives rise to balance flux equations that constrain, fully non-perturbatively, the asymptotic strain measured by gra…
Short Gravitational-Wave Transients as Probes of Cosmic Domain Walls
Tore Boybeyi, Doga Veske, David Maibach
GW190521 and GW231123 have been reported as short-duration gravitational-wave transients consistent with very massive binary black hole (BBH) coalescences whose inferred parameters…
Balance flux laws beyond general relativity
David Maibach, Jann Zosso
Balance flux laws of asymptotic symmetries in general relativity provide fully non-perturbative constraint equations on gravitational strain. They have proven useful for constructi…
Across the Horizon: On Gravitational Wave Flux Laws and Tests of Gravity
David Maibach
Motivated by the first detection of gravitational waves, this dissertation develops analytical, numerical, and data analysis techniques to address persistent blind spots in our und…
Signatures of Quantum Gravity in Gravitational Wave Memory
Nils Deppe, Lavinia Heisenberg, Lawrence E. Kidder +6
We study the impact of quantum corrections to gravitational waveforms on the gravitational wave memory effect. In certain quantum gravity theories and semi-classical frameworks, bl…
Echoes from beyond: Detecting gravitational-wave quantum imprints with LISA
Nils Deppe, Lavinia Heisenberg, Henri Inchauspé +7
We assess the prospects for detecting gravitational wave echoes arising due to the quantum nature of black hole horizons with LISA. In a recent proposal, Bekenstein's black hole ar…
