From March 9th to March 13th, Pisa will be home to the global gravitational waves community! EGO and Virgo will host the @ligo.org - Virgo - KAGRA Collaboration Meeting, the biannual meeting of the gravitational wave community, for the first time in Italy after more than a decade.

🧐 How many theories can be verified with a single #GravitationalWave signal? At least three, if this signal is GW250114, observed by the @ligo.org - Virgo - KAGRA Collaboration in January 2025.

The suspension goes into the chamber. I am the one holding the insertion arm on the right. This is a dangerous device, as its folds are effectively massive "scissors" ready to cut fingers or worse, so it has to be kept under control all the time. Video credit: Maryrose barrios. @ LIGO - Livingston

Later today!

🍂 What if a black hole born from the merger of two black holes merged with another black hole? We may find out thanks to gravitational waves, such as those observed by the @ligo.org - Virgo - KAGRA Collaboration in autumn 2024. Let's learn about these signals!

We see you are discussing with @cplberry.bsky.social. As the two LIGO detectors are nearly aligned, we are really only sensitive to one polarization (what you call that is arbitrary), but Virgo has a different alignment. This allows us to test polarization content e.g., ligo.org/science-summ...

The suspension was built in a clean room of the optics lab. It had to be transported to the interferometer. As it weighs close to 90kg we used a Genie lift with a special fixture we built. Here is the pickup moment. I am the one manning the crank. Video credit: Maryrose Barrios. @ LIGO - Livingston

It has been a busy first decade for gravitational-wave astronomy

Here is to another decade of discoveries!

#GW10Years

What I really love about this documentary is how in just a few minutes it shows the impact of the discovery—not just on science, but how it has inspired and motivated individuals, and how technology is finding applications in so many areas of life

I made this animation a few years ago but wasn't able to share it back then because gifs weren't supported. Now I can!

Happy Valentine's Day to all gravitational-wave fans, and especially @egovirgo.bsky.social and KAGRA 💞💗💓

Yesterday at Palazzo Farnese in Rome, we celebrated the tenth anniversary of the announcement of the discovery of gravitational waves with an event organised by
the Italian Ministry for University and Research, the Italian National Institute for Nuclear Physics (INFN), @cnrs.fr and EGO (more below)

Yesterday at the Planetarium of Rome, on the tenth anniversary of the announcement of the discovery of gravitational waves, the film for planetariums "Einstein Telescope, listening to the universe beyond the stars" was screened for the first time.

Yesterday marked 10 years since LSU Boyd Professor Gabriela González served as spokesperson for the 1,000+ member LIGO Scientific Collaboration to announce the first direct detection of gravitational waves.

I'm looking-forward to compering this exciting discussion on Thursday!

I refuse to accept that it's been TEN YEARS since I sat in that room 😭

A delicious representation of a binary black hole merger!

Perfect! We hope it is comfy

Sounds like a delicious hypothesis. Please let us know the conclusions of your research

Gravitational Waves

Today marks the 10th anniversary of the announcement of the direct detection of gravitational waves by @ligo.org. In honor of that milestone, we've put together a collection of our coverage of gravitational-wave research through the years. #LIGO #gravitationalwaves #physics #astronomy

Thank you. We hope you enjoy some treats in honor of the anniversary too!

Thank you Martin!
