| contents | We release the first Numerical Relativity catalog of Institut de Ciencies del Cosmos at University of Barcelona (ICCUB) consisting of 128 simulations for black hole binaries. All simulations in this first release correspond to highly eccentric binaries with eccentricity $e = (0.62,0.79)$ which develop zoom-whirls up to three close passages before merger. We consider aligned, equal spin configurations in the range $χ= (-0.5, 0.5)$ and equal mass ratios.
For each simulation, we provide the modes $(\ell, m)$ of Weyl scalar $ψ_4^{(\ell,m)}$ extrapolated to $r = \infty$, with $\ell \leq 4$. In addition, we provide the corresponding strain modes obtained by computing a double time integral of the Weyl scalar modes. Moreover, we provide metadata and the parameter files required to reproduce our results using the open-source code Einstein Toolkit.
A Python code that facilitates the access to the data is available on Git-Hub. |
