Abstract / Description of output

Cosmic void as a cosmological probe is reviewed. We introduce the theoretical background and recent development in observations of cosmic voids, focusing on its potential to test theorists of gravity. Four observables about cosmic voids are introduced: void number counts, weak gravitational lensing, redshift-space distortions and ISW around voids. We discuss opportunities on their application to current and future galaxy surveys and highlight challenges for this subject.
