Multimessenger Astrophysics
Many astrophysical phenomena release not just light (electromagnetic radiation), but also gravitational waves and/or elementary particles including neutrinos and cosmic rays. Each of those signals carries different information about the physics of the source, so collecting more than one enables us to have a deeper understanding of the event that produced them. However, it is an enormous challenge for different types of instruments to coordinate simultaneous observations, and to verify that signals have a common source. Projects like AMON and SciMMA help alert the community to potential multi-messenger events so that an observing program can be coordinated as quickly and efficiently as possible.
