Description
TianQin is a proposed space-based gravitational-wave observatory designed to explore the millihertz frequency band and to open a new window on gravitational-wave astronomy, fundamental physics, and cosmology. In this talk, I will review recent progress of the TianQin project, including its mission concept, technology roadmap, and key developments toward space-based detection, and discuss its main scientific prospects based on recent studies. TianQin is expected to observe a wide range of sources, including massive black hole binaries, extreme- and intermediate-mass-ratio inspirals, stellar-mass black hole binaries, Galactic compact binaries, and stochastic gravitational-wave backgrounds. These observations will provide new insights into black hole formation and growth, compact-object dynamics, binary evolution, and cosmic structure formation, while also enabling precision tests of general relativity, searches for new fundamental physics, and probes of the early Universe and cosmic expansion. Together with other ground- and space-based detectors, TianQin will contribute to a global multi-band gravitational-wave network and help advance gravitational-wave astronomy into a new era.
