An update of 2010 GWIC Roadmap intended to serve as strategic tool in planning for the development of capabilities and facilities needed to realize the scientific opportunities in gravitational-wave astronomy for the 2020s and 2030s.
The direct observation of gravitational waves from a binary black hole merger in 2015 by LIGO and Virgo ushered in the era of gravitational-wave astronomy and has been heralded as a watershed moment in science. Motivated by the rapid growth and evolution of the field in the last five years, GWIC commissioned an update of the 2010 GWIC Roadmap.
Like its 2010 predecessor, the goal of the 2021 GWIC Roadmap is to serve the international gravitational wave community and its stakeholders as a tool for the development of capabilities and facilities needed to address the exciting scientific opportunities on the intermediate and long-term horizons. The updated roadmap assesses future developments in ground-based, space-based, and pulsar timing array gravitational-wave detectors, surveys the potential for growth in bandwidth and sensitivity of future gravitational-wave detectors, and highlights the science results anticipated to come from these new instruments.
