This article appears to be from NASA's website, discussing a recent study on the electromagnetic emission of merging neutron stars. The study used supercomputer simulations to model the merger and predicted that future facilities may detect signals originating in the runup to the merger.
Here are some key points from the article:
1. The study used supercomputer simulations to model the merger of two neutron stars.
2. The simulation predicted that future medium-energy gamma-ray space telescopes, especially those with wide fields of view, may detect signals originating in the runup to the merger.
3. Ground-based gravitational-wave observatories, such as LIGO and Virgo, can detect neutron star mergers with frequencies between 10 and 1,000 hertz and can enable rapid electromagnetic follow-up.
4. A space-based gravitational-wave observatory named LISA (Laser Interferometer Space Antenna) is planned for launch in the 2030s and will observe neutron-star binaries much earlier in their evolution at far lower gravitational-wave frequencies than ground-based observatories.
5. Future gravitational-wave observatories will be able to alert astronomers to systems on the verge of merging, allowing them to begin searching for pre-merger emission using wide-field gamma-ray and X-ray observatories.
The article also includes a link to a NASA press release with more information about the study.
Overall, this article appears to provide an update on the current understanding of neutron star mergers and their potential detectability by future astronomical facilities.
