Description
We present the results of 14 simulations of nonspinning
black hole binaries with mass ratios $q=m_1/m_2$ in the range
$1/100\leq q\leq1$. For each of these simulations we perform three runs
at increasing resolution to assess the finite difference
errors and to extrapolate the results to infinite resolution.
For $q\geq 1/6$, we follow the evolution of the binary typically for the last
ten orbits prior to merger.
By fitting the results of these simulations, we accurately model the peak
luminosity, peak waveform frequency and amplitude,
and the recoil of the remnant hole for unequal mass
nonspinning binaries. We verify the accuracy of these new models and
compare them to previously
existing empirical formulas.
These new fits provide a basis for a hierarchical approach to produce
more accurate remnant formulas in the generic precessing case.
They also provide input to gravitational waveform
modeling and allow comparisons with perturbation theory.
