First binary black hole inspiral, merger, ringdown with SpECTRE

Created on October 2, 2024

We now have the first complete binary black hole inspiral, merger, & ringdown using our next-generation code SpECTRE! Our preprint [arXiv:2410.00265] presenting this first complete BBH simulation was led by Kyle Nelli (grad student at Caltech) and Geoffrey Lovelace (professor at CSU Fullerton).

Nonlinearities in black hole ringdowns

Created on August 17, 2022

With our latest preprint [arXiv:2208.07380] (led by Caltech grad student Keefe Mitman), SXS simulations have conclusively shown the presence of nonlinearities in black hole ringdowns. What does it all mean?
