Anniversary of the Gravitational-Wave Discovery
Today, we celebrate the anniversary of gravitational-wave astronomy. One year ago, on September 14, 2015, LIGO made the first direct detection of gravitational waves – tiny, rippling distortions in space and time – that were emitted by the tumultuous, dramatic collision of two black holes. Since then, LIGO has confirmed the detections of two binary black hole mergers (maybe even three!), and with LIGO’s second observing run starting later this fall, we anticipate many more detections in the years to come.
CITA is proud to contribute to this incredible work through the construction of waveform models and with numerical relativity simulations for the validation of systematic biases. We are also involved in developing LIGO’s search pipelines, which identified the gravitational-wave signals.
