EGO and the Virgo Collaboration
@egovirgo.bsky.social
Virgo is a Gravitational Wave detector, hosted by the European Gravitational Observatory (EGO), near Pisa, Italy.
Today marks the end of the fourth observing run of the @LIGO - Virgo - @KAGRA_PR gravitational wave detection network 🎆 It was the longest and richest run ever: 585 days and 250+ significant candidate signals, a huge increase from the 90 events of the three past runs combined🤯

@ligo.org, Virgo and KAGRA have observed 'second generation' black holes for the first time! 🕳️🕳️ In a new paper published today in The Astrophysical Journal Letters, the International Collaboration announced the observation of two very special gravitational signals

People of all ages got to learn about these extraordinary signals through which the universe tells its story and how we listen to them 👂

On September 14th 2015, the @LIGO - Virgo Collaboration finally detected gravitational waves, ripples in the "fabric" of space-time produced by events such as the merger of two black holes. Today we are happy to celebrate the 10th anniversary of this sensational discovery!

Exactly 10 years ago, the signal of a gravitational wave from the merger of two black holes arrived on Earth. It was not a special signal, but one like many that had always reached our planet. On that day, however, for the first time humankind was ready to listen to it. (1/7)

Just a few days before the 10th anniversary of gravitational wave detection, the @ligo.org - Virgo - KAGRA Collaboration is happy to announce a new major detection 📣 The signal, named GW250114, has provided us with the best observational proof to date of Stephen Hawking's black hole area theorem 🕳️🕳

It is with great sadness that we learn of the passing of Rainer Weiss, one of the fathers of gravitational wave research, founder of @ligo.org and Nobel Prize laureate in physics for the detection of gravitational waves in 2017.

Exactly eight years ago Virgo was detecting its first ever gravitational wave signal, the first signal ever caught by three gravitational wave detectors together: the two @ligo.org detectors and Virgo 🤝

We are deeply saddened to hear of the passing of Bob Wilson, world-renowned theater stage director and playwright that we had the honour and pleasure to welcome at EGO and Virgo in 2022, invited by Stavros Katsanevas.
