Cosmology with gravitational wave standard sirens: current results and future prospects

07.12.2018 14:15 – 15:15

I will introduce the concept of standard siren, reviewing the methodologies that one can apply to probe
the cosmic expansion using gravitational wave observations. I will then outline the gravitational wave
sources that can be used as standard sirens for both Earth-based (LIGO/Virgo) and space-based (LISA)
detectors, pointing out for which of them an electromagnetic counterpart is expected to be observed. I
will then discuss the constraints on the Hubble constant recently obtained from GW170817, which
represents the very first standard siren ever discovered, and discuss future cosmological prospects for
LIGO/Virgo. Finally I will present cosmological forecasts for LISA, which will be able to probe the
expansion of the universe at high redshift.
