Abstract
The last decade has brought about a profound transformation in multimessenger science.
Ten years ago, facilities had been built or were under construction that would eventually
discover the nature of objects in our universe could be detected through multiple messen gers. Nonetheless, multimessenger science was hardly more than a dream. The rewards
for our foresight were finally realized through IceCube’s discovery of the diffuse astrophys ical neutrino flux, the first observation of gravitational waves by LIGO, and the first joint
detections in gravitational waves and photons and in neutrinos and photons. Today we
live in the dawn of the multimessenger era.
The successes of the multimessenger campaigns of the last decade have pushed multi messenger science to the forefront of priority science areas in both the particle physics and
the astrophysics communities. Multimessenger science provides new methods of testing
fundamental theories about the nature of matter and energy, particularly in conditions that
are not reproducible on Earth. This white paper will present the science and facilities that
will provide opportunities for the particle physics community renew its commitment and
maintain its leadership in multimessenger science.
