Accurate initial data for Cauchy-characteristic evolution
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Accurate gravitational-wave (GW) templates from numerical-relativity (NR) simulations are essential for GW science. These templates are typically computed at finite radii and extra…
Calculating gravitational waves at infinity: the missing link
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Gravitational-wave science requires waveform templates to be computed at future null infinity, the asymptotic boundary of spacetime. Numerical solutions of Einstein's equations typ…
How accurate is Spectral Einstein Code (SpEC)? And what limits its accuracy?
Himanshu Chaudhary, Mark A. Scheel, Robert Owen +4
The improved sensitivity of upcoming gravitational-wave detectors will require correspondingly more accurate binary black hole (BBH) simulations. Given the high cost of such simula…
Finding black hole spins efficiently during a numerical binary evolution
Himanshu Chaudhary, Rob Owen, Mark A. Scheel +1
The dynamics of a binary black hole system depend on its masses and spins. For a binary at finite separation, it is not possible to define these quantities in an unambiguous way; h…
Equatorial Periodic Orbits and Gravitational Wave Phenomenology around Spherically-symmetric vacuum solution in Freund-Nambu scalar-tensor gravity
Dhruba Jyoti Gogoi, Jyatsnasree Bora, Himanshu Chaudhary +2
We investigate test particle dynamics and gravitational wave (GW) phenomenology in an exact spherically symmetric vacuum solution of Freund - Nambu scalar - tensor gravity. This fr…
Schrödinger-type gravity-nonmetricity driven cosmological evolution from inflation to the late Universe
Lei Ming, Himanshu Chaudhary, Shi-Dong Liang +2
We consider an gravity theory with a Schrödinger type vectorial non-metricity. In the presence of such a non-metricity, the length of vectors is preserved under autoparal…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
Yano-Schrödinger Hyperfluid: Cosmological Implications
Himanshu Chaudhary, Saddam Hussain
Perfect cosmological hyperfluids generalize the concept of a perfect fluid within the framework of metric affine gravity. These hyperfluids encode the microstructure of matter incl…
