Gravitational Waves as Probes for New Physics Gravitational Waves as Probes for New Physics

Speaker

Gianluca Calcagni

Description

We review recent results about tests of quantum gravity with
gravitational waves, using modified dispersion relations and the
luminosity distance of standard sirens. Theoretical models predicting
signals observable with LIGO-Virgo-KAGRA and LISA are discussed. The
gravitational-wave physics of a recent nonlocal theory with fractional
operators and infrared corrections to gravity is presented for the first
time.
