List of gravitational wave observations

This page contains a list of observed and candidate gravitational wave events. Gravitational waves are ripples in space caused by some of the most powerful events in the universe, like the collision of black holes or the explosion of big stars. These waves travel at the speed of light and can pass through anything, giving us a new way to study the universe.

The first gravitational waves were detected in 2015 by a special instrument called LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory. Since then, scientists have been observing more of these waves, learning about the objects that create them and the nature of space itself.

These observations help us understand how the universe works in ways we could not see before. By studying gravitational waves, scientists can learn about black holes, neutron stars, and other mysterious objects that are normally invisible. This new kind of "listening" to the universe opens many exciting possibilities for discovery.

Origin and nomenclature

The first direct detection of gravitational waves happened in 2015 by LIGO. Since then, scientists have been watching for these tiny ripples in space caused by big events in the universe, like when two black holes or two neutron stars crash into each other. Other tools like Virgo and KAGRA have joined in to help make even more discoveries.

Each time scientists look for these waves, they call it an "observing run," like O1, O2, O3, and so on. These runs can last many months, with breaks in between to make the machines even better at spotting these tiny waves. For example, O1 started in September 2015 and found its first gravitational wave. Later runs like O4 began in May 2023 and will continue through 2025, with more runs planned for the future. When a possible wave is seen but not fully confirmed, it gets a special name that starts with "S," and confirmed events start with "GW."

List of gravitational wave events

Gravitational waves are ripples in space made by big events in the universe, like stars or black holes crashing together. Scientists have seen many of these events using special tools like LIGO and Virgo. These discoveries help us learn more about space and the things inside it.

The events were recorded from 2015 to 2023. They show us how far away these events happened and how heavy the objects were. These findings are important for learning more about the universe.

Candidate events and marginal detections

Scientists are always looking for new clues about space and time. They study very small changes in gravity called gravitational waves. Some of these changes might come from far away in space, but we are not completely sure yet.

Special machines called LIGO and Virgo tried to catch these waves. They found some signs that might be waves, but they need more proof to be certain. These signs came at different times, like in December 2015 and August 2017. Scientists keep looking and checking to learn more.
