LIGO-Virgo-KAGRA Release Data on Record 225-Solar-Mass Black Hole Merger
UNITED STATES, JUL 14 – The merger formed a black hole 225 times the Sun's mass, challenging stellar evolution models and suggesting complex or hierarchical formation, researchers said.
- The LIGO-Virgo-KAGRA Collaboration detected a black hole merger with a mass of 225 times that of the sun, marking it as the most massive yet recorded.
- Previously, the largest black hole merger was 140 times the sun's mass, noted from an event in 2021 called GW190521.
- Gravitational waves are providing unique insights into the nature of black holes, highlighting their fundamental properties.
- The observation showcases advancements in instrumentation and data-analysis in gravitational-wave astronomy.

Biggest black hole merger ever breaks the universe’s rules
This is the most massive black hole binary we’ve observed through gravitational waves, and it presents a real challenge to our understanding of black hole formation. Black holes this massive are forbidden through standard stellar evolution models. One possibility is that the two black holes in this binary formed through earlier mergers of smaller black holes.
The merger created a black hole with a mass approximately 225 times that of the Sun. The most massive black hole merger ever observed by gravitational waves was detected by the LIGO observatory on November 23, 2023, as part of the three-observatory collaboration, LIGO-Virgo-KAGRA (LVK).
Livingston LIGO, collaborators announce detection of largest observed black hole merger
LIVINGSTON — Ahead of its 10th anniversary celebration in September, Livingston LIGO announced a monumental discovery about black holes earlier this week in Europe.On Monday in Glasgow, Scotland, representatives from the Livingston facility, a Laser Interferometer Gravitational-wave Observatory, announced that it was one of two sites to detect a black hole 225 times the size of the Sun.The phenomenon, designated GW231123, was observed in Novembe…
