There are black holes that are too big to be born from the death of a star but aren’t quite supermassive either. There’s ...

In November 2024, gravitational-wave detectors recorded the violent merger of two black holes billions of light-years away. Normally, such events are invisible to telescopes, producing only faint ...

This black hole merger animation was created using data collected by the LIGO and Virgo gravitational wave detectors, an ...

For just one-tenth of a second in May 2019, the universe delivered a signal that did not fit the usual script. LIGO and Virgo recorded a gravitational wave from GW190521, but unlike the familiar ...

Researchers from the University of Glasgow's Institute for Gravitational Research are celebrating the publication of a vast ...

In 2020, astronomers discovered a violent cosmic event that has led them to rethink how extreme pairs of astronomical objects form. These pairs are capable of producing powerful cosmic collisions. The ...

While scientists know supermassive black holes collide, these events have remained invisible to telescopes. RIT researchers have now identified a specific spike in light that occurs at the moment of ...

Physicists have detected the biggest ever merger of colliding black holes. The discovery has major implications for researchers’ understanding of how such bodies grow in the Universe. “It’s super ...

The biggest black holes in the Universe may be built through chains of violent mergers deep inside crowded star clusters.

At some 60 billion times the mass of the sun, this dark void could be home to a pair of black holes that are due for a cosmic collision.
