International research team succeeds for the first time in analysing different signals simultaneously. Numerical simulation of the ejected material resulting from two merging neutron stars. Red colors refer to ejected material with a low fraction of protons. Blue material contains a high fraction of protons. Image: Ivan Markin (University of Potsdam) - A new method to study the signals associated with merging neutron stars can help researchers to collect data through multiple channels in parallel. The method was developed by an international team of scientists, including the Institute for Gravitational and Subatomic Physics (GRASP) , Utrecht University, and Nikhef. By analysing a neutron star merger's emitted gravitational waves, the kilonova, and the afterglow of the gamma-ray burst simultaneously, it was possible to model and interpret most of the observable signals from the merger for the first time.
