Numerical simulation of the compact binary system GW230529: Matter and waves

The visualization shows the coalescence and merger of a lower mass-gap black hole (dark grey surface) with a neutron star with colors ranging from dark orange (1 million tons per cubic centimeter) to white (600 million tons per cubic centimeter). The animation is accompanied by the gravitational-wave signal represented with a set of strain amplitude values of plus-polarization using colors from dark blue to cyan. The gravitational waveform is shown at the bottom of the video, with a moving marker displaying the time relative to the merger. © I. Markin (Potsdam University), T.
