Enroll in Open Data Workshop #6

Join over 2,000 people around the world who have enrolled in the 6th GW Open Data Workshop. The workshop presents a crash-course in gravitational-wave data analysis, including lectures, software tutorials, and a data challenge. The materials were developed for a hybrid workshop held May 15-17, 2023, that included hundreds of participants at 20 Study Hub locations.

O4 Observing Run is Underway!

LIGO, Virgo, and KAGRA began a new observing run on May 24, 2023, after three years of commissioning work.

This observing run, known as O4, promises to take gravitational-wave astronomy to the next level. O4 is planned to last 20 months, including up to two months of commissioning breaks. It will be the most sensitive search yet for gravitational waves. LIGO began operations on May 24th, while Virgo will join later in the year. KAGRA will observe for one month, beginning May 24th, rejoining later in the run after some upgrades.
