Kerr metric perturbations for second-order self-force theory
Benjamin Leather, Samuel D. Upton, Patrick Bourg +8
We present a calculation of the first-order metric perturbation arising from a point mass moving on a circular, equatorial orbit in Kerr spacetime. The metric perturbation is speci…
LISA science ground segment conventions
Quentin Baghi, Stanislas Babak, Leor Barack +23
This document sets out the conventions used for data simulations, waveforms, and analysis pipelines within the Distributed Data Processing Centre (DDPC) of the Laser Interferometer…
Constants of motion in gravitational self-force theory
David Trestini, Zachary Nasipak, Adam Pound
Synergies between self-force theory and other approaches to the gravitational two-body problem have traditionally relied on calculations of gauge-invariant observables as functions…
Systematic errors in fast relativistic waveforms for Extreme Mass Ratio Inspirals
Hassan Khalvati, Philip Lynch, Ollie Burke +3
Accurate modeling of \gls{EMRIs} is essential for extracting reliable information from future space-based gravitational wave observatories. Fast waveform generation frameworks adop…
Metric reconstruction and the Hamiltonian for eccentric, precessing binaries in the small-mass-ratio limit
Zachary Nasipak
We calculate the first-order (in the mass-ratio) metric perturbation produced by a small body on an eccentric, precessing bound orbit about a Kerr black hole. We reconstruct the me…
The Fast and the Frame-Dragging: Efficient waveforms for asymmetric-mass eccentric equatorial inspirals into rapidly-spinning black holes
Christian E. A. Chapman-Bird, Lorenzo Speri, Zachary Nasipak +13
Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient wav…
Connecting scattering, monodromy, and MST's renormalized angular momentum for the Teukolsky equation in Kerr spacetime
Zachary Nasipak
The Teukolsky equation describes perturbations of Kerr spacetime and is central to the study of rotating black holes and gravitational waves. In the frequency domain, the Teukolsky…
KerrGeoPy: A Python Package for Computing Timelike Geodesics in Kerr Spacetime
Seyong Park, Zachary Nasipak
KerrGeoPy is a Python package which computes both stable and plunging timelike geodesics in Kerr spacetime using analytic solutions to the geodesic equation that are written in ter…
BHPWAVE: An adiabatic gravitational waveform model for compact objects undergoing quasi-circular inspirals into rotating massive black holes
Zachary Nasipak
We present {bhpwave}: a new Python-based, open-source tool for generating the gravitational waveforms of stellar-mass compact objects undergoing quasi-circular inspirals into rotat…
Adiabatic evolution due to the conservative scalar self-force during orbital resonances
Zachary Nasipak
We calculate the scalar self-force experienced by a scalar point-charge orbiting a Kerr black hole along -resonant geodesics. We use the self-force to calculate the averaged ra…
Advancing the Landscape of Multimessenger Science in the Next Decade
Kristi Engel, Tiffany Lewis, Marco Stein Muzio +91
The last decade has brought about a profound transformation in multimessenger science. Ten years ago, facilities had been built or were under construction that would eventually dis…
Resonant self-force effects in extreme-mass-ratio binaries: A scalar model
Zachary Nasipak, Charles R. Evans
Extreme-mass ratio inspirals (EMRIs), compact binaries with small mass ratios , will be important sources for low-frequency gravitational wave detectors. Almost all EMRIs w…
Repeated faint quasinormal bursts in extreme-mass-ratio inspiral waveforms: Evidence from frequency-domain scalar self-force calculations on generic Kerr orbits
Zachary Nasipak, Thomas Osburn, Charles R. Evans
We report development of a code to calculate the scalar self-force on a scalar-charged particle moving on generic bound orbits in the Kerr spacetime. The scalar self-force model al…
The Baryonic Collapse Efficiency of Galaxy Groups in the RESOLVE and ECO Surveys
Kathleen D. Eckert, Sheila J. Kannappan, Claudia del P. Lagos +6
We examine the z = 0 group-integrated stellar and cold baryonic (stars + cold atomic gas) mass functions (group SMF and CBMF) and the baryonic collapse efficiency (group cold baryo…
