When two black holes collide, they release gravitational waves that allow scientists to determine their mass and spin. In January 2025, LIGO detected GW250114, the clearest signal yet of a black hole merger, providing new insights into these mysterious cosmic giants. Credit: Maggie Chiang for Simons Foundation

Mystery solved: How the "impossible" merger of two giant black holes occurred

New simulations from the Center for Computational Astrophysics at the Flatiron Institute suggest that the formation of black holes in the "forbidden" mass range results from a combination of rapid rotation and strong magnetic fields, which eject up to half of the star's mass and create

An extremely strong gravitational wave measured at LIGO has made it possible for the first time to experimentally verify the principle that the area of ​​a black hole's event horizon cannot decrease. Concern: The government wants to close the LIGO project
Two massive black holes have collided in deep space, creating a final monster that defies current theories. Scientists say it's the most massive, fastest-spinning merger ever discovered.

LIGO gravitational wave detectors are about to undergo an upgrade

  • No comments
Scientists have developed an innovative optical system designed to improve the sensitivity of the LIGO detector, the American gravitational wave detector that was a partner, along with the European Virgo, in the initial detection of gravitational waves and in many subsequent discoveries.

The analysis of the signal GW230529 picked up by LIGO shows that it originated from the merger of two compact objects, one with a mass between 1.2 and 2.0 times that of the Sun and the other with a mass slightly more than twice the first

"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.

This image provides three different perspectives on the gamma ray burst GRB150101B, which is similar to the event where gravitational waves were measured and simultaneously also in the electromagnetic spectrum and there is a similarity between the two cases. In the center, an image from the Hubble Space Telescope shows the galaxy where the GRB150101B burst occurred. In the top corner, two X-ray images from NASA's Chandra X-ray Observatory show the event as it appeared on January 9, 2015 (left), and as seen about a month later, on February 10, 2015 (right), as the explosion halo fades, point The bright light is the nucleus of the galaxy.Photo: NASA/CXC

Illustration illustrating what two merging black holes look like similar to those detected by LIGO. The black holes rotate misaligned meaning they have different orientations relative to the general motion of the binary orbit. LIGO has found clues that the orbit of at least one black hole in the GW170104 system was previously undetected through its orbital motion before it merged with its partner.
