Alessandro speaks on GW190521 as dynamical capture of two nonspinning black holes, presenting our Nature Astronomy paper. Here we use our  TEOBResumS waveform model to  analyze GW190521 under te assumption the signal was generated by a dynamical encounter of two black holes instead of two objects on a bound, quasi-circular, orbit.
