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.
