Beyond Advanced LIGO: the future of ground based observations

 

Abstract: Advanced LIGO started the era of gravitational wave astronomy during its first observing run, O1, in 2015. Since then, the international gravitational wave community has been making plans to define the future of ground based gravitational wave observations. In this talk I will discuss current ideas for extending the astrophysical reach of ground based gravitational wave detectors up to a factor 10-20 beyond Advanced LIGO.
