New gravitational wave signal helps fill the ‘mass gap’ between neutron stars and black holes
April 8, 2024
A collaboration of researchers including UBC scientists have observed gravitational waves from the collision of what is most likely a neutron star and an object likely to be a light black hole, 650 million light-years from Earth.
The mass of the black hole is 2.5 to 4.5 times the mass of Earth’s sun, meaning it falls in the so-called ‘mass gap’: heavier than heaviest known and theorized neutron stars but lighter than the lightest black holes in our galaxy.
