Time-Domain Resources
Time-domain and multimessenger science is a critical component of the Fermi mission, leveraging the telescope's role as a powerful survey instrument. Phenomena such as novae, supernovae, gamma-ray bursts, magnetars, active galactic nuclei, binaries, gravitational waves, ultra-high energy cosmic rays, and neutrinos are routinely monitored by the LAT and GBM instruments. With its large field-of-view capabilities, Fermi has achieved numerous groundbreaking multimessenger discoveries, including:
- Gamma-ray observations of the first direct gravitational-wave detection from a black hole merger
- The first unambiguous observation of gravitational waves resulting from a neutron star merger
- A high-energy neutrino event aligned with the position of the TXS 0506+056 blazar
- The detection of the brightest GRB ever observed, GRB 221009A
These represent just a selection of the results made possible by Fermi.
Below, we have compiled relevant resources for the time-domain and multimessenger community.
