SUMMARY:Stefano di Angelis on "Gravitational waveforms from Amplitudes" - 
DESCRIPTION:Speaker: Stefano di Angelis\n\nTitle: Gravitational waveforms f
 rom Amplitudes\n\nAbstract: I will start by reviewing the KMOC formalism f
 or computing the waveform from scattering amplitudes and the one-year-old 
 computation of the one-loop five-point function. Then\, the focus of the t
 alk will be two-fold.\n\nIn the small velocity expansion\, analytic result
 s can be computed using the Multipolar-post-Minkowskian (MPM) approach. Do
  amplitude results agree with MPM?\nThe computation of the analytic wavefo
 rm notoriously has several subtleties (such as spurious poles and the Four
 ier transform to impact parameter space). I will propose some new techniqu
 es to deal with these difficulties.\n\nThis talk will be in hybrid mode vi
 a zoom\, please contact the seminar organisers to obtain the password.\nTo
