Black holes in eccentric orbit

Gravitational wave observatories LIGO and Virgo captured a signal in 2019 that differed from previous measurements. Researchers found an alternative explanation: the collision occurred on a strongly eccentric path, where one black hole was initially free to move before being captured by another's gravitational field.
