"Exploring New Frontiers: The Impact of Space Lasers on Gravitational Wave Research"

Gravitational wave astronomy has opened up four frontiers in the study of black holes, including the detection of the most massive black holes, supermassive black holes, intermediate mass black holes, and the boundary between neutron stars and black holes. Ground-based and space-based detectors, as well as pulsar timing arrays, are being used to push these frontiers, with the ultimate goal of characterizing the entire population of black holes throughout the Universe. Advances in technology and observational techniques are expected to provide robust data to answer these fundamental questions in the coming decades.
