SPARTANS: A Catalog of eccentric black hole inspiral to merger waveforms
ORAL
Abstract
We perform a systematic series of eccentric (e), from comparable to intermediate mass ratio (q), spinning (a), binary black holes simulations.
We chose a set of variables, f(e), nu(q), Shu(a), to efficiently cover with long term evolutions of at least 20 orbits before merger the nonprecessing parameter space.
SPARTANS is a catalog to provide an initial set of 150 simulatins to be suplemented, in a staggered grid, by another 150 simulations.
An assessment of the accuracy is provided to discard any systematic errors when used for parameter estimation of gravitational waves signals.
