This image shows the merger of a lower mass-gap black hole (dark grey surface) with a neutron star with colours ranging from dark orange (1 million tons per cubic centimetre) to white (600 million tons per cubic centimetre). The gravitational wave signal is 2 represented with a set of strain amplitude values of plus-polarisation using colours from dark blue to cyan.
