Getting gravitational waveforms right from the start

Created on November 2, 2026

Gravitational waves travel hundreds of millions to billions of light-years before reaching our detectors. Numerical simulations of merging black holes, however, cover only a finite region around them. To predict the signal far away, we hand data from the simulation to a second calculation that carries the radiation all the way to infinity.

Keefe Mitman featured on Fraser Cain’s podcast

Created on March 19, 2026

A postdoctoral researcher in our collaboration, Keefe Mitman —a NASA Hubble Fellow at Cornell University, was recently featured in a Youtube video by journalist Fraser Cain: Everything You Need to Know About Gravitational Waves in 2026. In the video, Keefe and Fraser discuss recent progress by the LVK gravitational-wave detectors as well as the potential future of gravitational-wave science and everything that it has to offer.

And be the Eternal Mirror that you saw:
Rays that have wander'd into Darkness wide,
Return and back into your Sun subside.
