Open AccessMultipole expansion of gravitational waves: memory effects and Bondi aspects
In our previous work, we proposed an algorithm to transform the metric of an isolated matter source in the multipolar post-Minkowskian approximation in harmonic (de Donder) gauge to the Newman-Unti gauge. We t...

Open AccessMultipole expansion of gravitational waves: from harmonic to Bondi coordinates
We transform the metric of an isolated matter source in the multipolar post-Minkowskian approximation from harmonic (de Donder) coordinates to radiative Newman-Unti (NU) coordinates. To linearized order, we ob...
