The first-ever detection of gravitational waves and light from the collision of two neutron stars isn't just setting the scientific community ablaze. It also ushers in a new "multi-messenger" astronomy, with scientists arround the world gathering and studying those waves, light, and subatomic particles at the same time. So says Laura Cadonati, professor in the School of Physics and the deputy spokesperson for the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration, and she explains the significance of this new era. Cadonati is also a member of the Center for Relativistic Astrophysics.
