Cosmic Explorer: The U.S. Contribution to Gravitational-Wave Astronomy beyond LIGO
arXiv:1907.04833
Abstract
This white paper describes the research and development needed over the next decade to realize "Cosmic Explorer," the U.S. node of a future third-generation detector network that will be capable of observing and characterizing compact gravitational-wave sources to cosmological redshifts.
