Project Grant 2513486

The National Science Foundation Directorate for Mathematical and Physical Sciences awarded Northeastern University $223,099 on August 15, 2026, to develop advanced mirror coatings for third-generation gravitational-wave detectors, specifically the Cosmic Explorer (CE), a proposed 40-kilometer detector that will extend gravitational-wave observations to high redshifts and enable detection of stellar-size events at cosmological distances.

The Center for Coatings Research (CCR) project addresses the technical challenge of creating mirror coatings with unprecedentedly low optical absorption and minimal thermal noise from internal friction while supporting 1.5 megawatts of optical power in the detector's arms. The research combines materials science and gravitational-wave physics communities and provides research opportunities for students across multiple education levels. Broader scientific impacts extend to precision measurement technology including precision timing, quantum information, low-noise interferometry, and tests of the gravitational inverse-square law. Research outcomes carry technological implications for semiconductor, laser, and quantum computing communities as correlations between optical and mechanical loss mechanisms are explored.

Performance occurs in Boston, Massachusetts, with work completion scheduled for July 31, 2028. The award is classified as a Project Grant under the Mathematical and Physical Sciences program (CFDA 47.049).
