Only A Supercomputer Can Understand the Extremely Energetic Chaos of a Neutron Star Merger
- Latest simulations show the last moments before neutron stars merge generate rapidly changing magnetospheres that can drive precursor electromagnetic signals.
- The research used NASA's Pleiades supercomputer to simulate merging neutron stars with 1.4 solar masses each.
- The simulations indicate some photons reach TeV–PeV energies, but many cannot escape the strong magnetic fields.
- Observers’ perspective and magnetic orientation significantly shape the detected signals and their strength.
- Magnetosphere dynamics can influence gravitational wave signals in next-generation observatories.
- The study pinpoints the last 7.7 milliseconds of inspiral as critical for magnetospheric evolution and EM output.
- Premerger magnetospheric state may play a crucial role in shaping overall electromagnetic luminosity.
- The horizon for detection includes MeV band as a promising observational window for precursor signals.
- The team highlights a rich phenomenology and how magnetospheric interactions could affect future observatories.
- The study emphasizes a link between magnetic field dynamics and emitted signals during NS mergers.
