Recent discoveries of black hole mergers and the collision of neutron stars by the Laser Interferometer Gravitational wave Observatory (LIGO) have opened up the era of gravitational wave astronomy and mutimessenger astronomy. The Advanced LIGO detectors are currently being upgraded in preparation for their third observing run (O3), looking forward to more gravitational wave detections including the possibility of the first un-modeled gravitational wave signals. Beyond Advanced LIGO, the future of gravitational wave astronomy includes the Laser Interferometer Space Antenna (LISA) mission led by the European Space Agency (ESA). Meanwhile, Pulsar Timing Arrays (PTAs) such as the North American Nanohertz Observatory for Gravitational waves (NANOGrav) are poised to make detections of gravitational waves in the nanohertz range. The historic first detections of gravitational waves have opened a new way to study our universe, with discovery potential across the entire gravitational wave spectrum.
