The effect of pressure confinement on the maximum mass of rapidly accreting supermassive stars
Lorenz Zwick, Christopher Tiede, Zoltán Haiman
We derive an extension of Chandrasekhar's pulsational stability criterion for relativistic stars with a pressure boundary condition at the surface. We then apply the new criterion…
A parametrized test of general relativity for inspiralling eccentric binaries in LISA
Pankaj Saini, Sylvain Marsat, Lorenz Zwick +2
The space-based detector Laser Interferometer Space Antenna (LISA) will observe inspiralling black hole binaries in the mHz band, many of which may retain orbital eccentricity. In…
Probability of gravitational-wave lensing by intermediate-mass black holes and globular clusters
Luka Vujeva, Jose María Ezquiaga, Rico K. L. Lo +1
Strongly lensed gravitational waves (GWs) are powerful probes of substructure in the lens. Intermediate-mass black holes (IMBHs) are postulated to be efficient lenses that may dist…
Dynamics of Relativistic Binaries in Structured and Stochastic Environments: A Lagrange-Fourier-Hansen Framework
Lorenz Zwick, Conor Dyson, Brian C. Seymour +2
We develop a general framework to characterize non-vacuum perturbations to relativistic binaries in the gravitational-wave (GW) driven regime, for use in GW parameter estimation st…
Multi-messenger and Multi-band Studies of Massive Black Holes: the Synergies Between LISA and SKAO
Pedro R. Capelo, Alberto Mangiagli, Lorenz Zwick +2
Depending on its mass, the same gas-embedded massive black hole (BH) binary can emit gravitational waves (GWs) in one or more bands (nHz and mHz) concurrently, along with electroma…
Orbital eccentricity can make neutron star g-mode resonances observable with current gravitational-wave detectors
János Takátsy, Lorenz Zwick, Pankaj Saini +1
Dynamical tides can provide us vital information about the properties of neutron star (NS) matter. This is particularly true for g-modes, whose frequency and tidal coupling are hig…
Towards gravitational wave parameter inference for binaries with an eccentric companion
Kai Hendriks, Lorenz Zwick, Pankaj Saini +2
We introduce a complete model for dephasing due to line-of-sight acceleration (LOSA) in gravitational wave (GW) signals from stellar-mass binary black holes (BBHs) in three-body sy…
Limits of vacuum-template subtraction for LISA massive black hole binary sources in realistic environments
Lorenz Zwick
We investigate the impact of gravitational wave (GW) dephasing due to gas accretion on the subtraction of massive black hole (MBH) binary signals over 4 yr of LISA data in the cont…
