The distance ladder relying on supernovae yields higher values of the Hubble constant H0 than those inferred from the inverse distance ladder, calibrated on early-time physics and relying on observations typically involving cosmic microwave background (CMB) in combination with galaxy surveys. Such discrepancy has come to be known as the ‘Hubble tension’. This has motivated the exploration...
The observation of gravitational waves by the LIGO/Virgo collaborations and the promise of future experiments underscores the need for increasingly more precise theoretical predictions. It has recently been demonstrated that scattering-amplitude techniques, originally developed for QCD calculations, can push the state of the art and provide results that are difficult to obtain by more standard...
