Observing the black hole mergers in the early universe with next-generation gravitational wave observatories

Deadline: Open all year round
Self Funded

Project Description

The Einstein Telescope and Cosmic Explorer are proposed next-generation gravitational-wave observatories which will be able to detect black hole mergers throughout the observable universe. Thus, observations of black hole mergers have the potential to provide insights into the formation of the first stars, and of the seed black holes which grow to form the supermassive black holes observed in the centres of galaxies. This project will involve developing tools to probe the ability of Einstein Telescope and Cosmic Explorer to observe black hole mergers in the early universe and the accuracy with which their properties (most importantly masses, spins and redshift) can be measured. The results will be used to investigate the ability of gravitational wave observations to probe the formation and evolution of the first black holes in the universe.
