Heaviest black hole merger yet is a first for discoveries
... that the larger object may have been the result of a previous black hole merger rather than a single collapsing star. This type of hierarchical combining of black holes has been hypothesised before but GW190521 would be the first evidence for...

A first of its kind white dwarf merger with a dense compact object discovered by students
...) – the facility that recorded the event – on the hunt for more. Current reports suggest that binary black hole mergers are being discovered by LIGO and its sister facility, Virgo, at a rate of one discovery per week. Now...

Virgo and LIGO detect fourth gravitational wave signal
... of two, the LIGO team and the Virgo Collaboration jointly report that a fourth confirmed detection of a binary black hole merger has been recorded. It is the first time that both scientific collaborations have worked together to pin down...

More surprises for neutron star merger GW170817
... ripples permeating through the fabric of space-time were caused not by two colliding black holes but by the merger of two neutron stars instead. Black holes and neutron stars both form from the same thing – massive stars, and...

Gravitational waves expel black hole from galaxy centre
... evidence of black hole collisions for stellar-mass black holes, but the process regulating supermassive black holes is more complex and not yet completely understood." It is thought that not every merger between black holes generates an imbalance...

Researchers probe black-hole mergers with fast-powered winds
... disks have been postulated as the cause of this event. In order to shed more light on the turbulent environment of a black-hole merger, scientists have considered the implications of a wind, powered by an active mini-disk – a small disk that may aid...
