Gravitational waveforms from SpEC simulations : neutron star-neutron star and low-mass black hole-neutron star binaries
Francois Foucart, Matthew D. Duez, Tanja Hinderer +9
Gravitational waveforms from numerical simulations are a critical tool to test and analytically calibrate the waveform models used to study the properties of merging compact object…
Surrogate model of hybridized numerical relativity binary black hole waveforms
Vijay Varma, Scott E. Field, Mark A. Scheel +3
Numerical relativity (NR) simulations provide the most accurate binary black hole gravitational waveforms, but are prohibitively expensive for applications such as parameter estima…
Evolving Metric Perturbations in dynamical Chern-Simons Gravity
Maria Okounkova, Mark A. Scheel, Saul A. Teukolsky
We present a well-posed constraint-preserving scheme for evolving first-order metric perturbations on an arbitrary background with arbitrary source. We use this scheme to evolve th…
Numerical black hole initial data and shadows in dynamical Chern-Simons gravity
Maria Okounkova, Mark A. Scheel, Saul A. Teukolsky
We present a scheme for generating first-order metric perturbation initial data for an arbitrary background and source. We then apply this scheme to derive metric perturbations in…
Systematic effects from black hole-neutron star waveform model uncertainties on the neutron star equation of state
Kabir Chakravarti, Anuradha Gupta, Sukanta Bose +12
We identify various contributors of systematic effects in the measurement of the neutron star (NS) tidal deformability and quantify their magnitude for several types of neutron sta…
Comparison of binary black hole initial data sets
Vijay Varma, Mark A. Scheel, Harald P. Pfeiffer
We present improvements to construction of binary black hole initial data used in SpEC (the Spectral Einstein Code). We introduce new boundary conditions for the extended conformal…
Constraining the parameters of GW150914 & GW170104 with numerical relativity surrogates
Prayush Kumar, Jonathan Blackman, Scott E. Field +7
Gravitational-wave detectors have begun to observe coalescences of heavy black holes at a consistent pace for the past few years. Accurate models of gravitational waveforms are ess…
Constructing a boosted, spinning black hole in the damped harmonic gauge
Vijay Varma, Mark A. Scheel
The damped harmonic gauge is important for numerical relativity computations based on the generalized harmonic formulation of Einstein's equations, and is used to reduce coordinate…
Black hole-neutron star mergers using a survey of finite-temperature equations of state
Wyatt Brege, Matthew D. Duez, Francois Foucart +7
Each of the potential signals from a black hole-neutron star merger should contain an imprint of the neutron star equation of state: gravitational waves via its effect on tidal dis…
Measuring the properties of nearly extremal black holes with gravitational waves
Katerina Chatziioannou, Geoffrey Lovelace, Michael Boyle +7
Characterizing the properties of black holes is one of the most important science objectives for gravitational-wave observations. Astrophysical evidence suggests that black holes t…
Detection and characterization of spin-orbit resonances in the advanced gravitational wave detectors era
Chaitanya Afle, Anuradha Gupta, Bhooshan Gadre +12
In this paper, we test the performance of templates in detection and characterization of Spin-orbit resonant (SOR) binaries. We use precessing SEOBNRv3 waveforms as well as {\it fo…
Critical behavior in 3-d gravitational collapse of massless scalar fields
Nils Deppe, Lawrence E. Kidder, Mark A. Scheel +1
We present results from the first study of critical behavior in 3-d gravitational collapse. The source of the gravitational field is a massless scalar field. This is a well-studied…
