Astrophysical sources emit gravitational waves in a large variety of processes occurring since the beginning of star and galaxy formation. These waves permeate our high-redshift Universe and form a background which is the result of the superposition of different components, each associated with a specific astrophysical process. Each component has different spectral properties and features that are important to investigate in view of a possible, future detection. In this contribution, we will review recent theoretical predictions for backgrounds produced by extragalactic sources and discuss their detectability with current and future gravitational wave observatories.

Abstract
Astrophysical sources emit gravitational waves in a large variety of processes occurring since the beginning of star and galaxy formation. These waves permeate our high-redshift Universe and form a background which is the result of the superposition of different components, each associated with a specific astrophysical process. Each component has different spectral properties and features that are important to investigate in view of a possible, future detection. In this contribution, we will review recent theoretical predictions for backgrounds produced by extragalactic sources and discuss their detectability with current and future gravitational wave observatories.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
