GRAVITATIONAL WAVE AND MULTIMESSENGER ASTROPHYSICS

The era of multimessenger astrophysics, which utilizes observation data from gravitational wave detectors and neutrino detectors, in addition to the traditional electromagnetic observations in optical bands, radio frequencies, X-rays, and gamma-rays, has just began. We have recently started a Seed program on Multimessenger Astrophysics at National Center for Theoretical Sciences. We have also joined the Kamioka Gravitational Wave Detector (KAGRA) collaborations. Our group provide and predict gravitational wave templates from multi-dimensional core-collapse supernova simulations and help to search of possible detections in the near future.

Multimessenger Astrophysics Program at NCTS

With support from the NCTS, we have established a new seed program on multimessenger astrophysics since January 2019. The main purpose of this seed project is to build and coordinate domestic collaborations on the theoretical aspects of multimessenger astrophysics and to attract potential students to join this exciting research frontier. In this program, we gathered experts from neutrino physics, high energy physics, nuclear physics, supernova physics, and cosmology working together on four sub-topics of multimessenger astrophysics: (1) kilonova and neutron star mergers, (2) the gravitational wave and neutrino emissions from core-collapse supernovae, (3) relation with the cosmological structure formation, and (4) astrophysical code developments.
