| Summary:

The opening of the gravitational wave window has significantly enhanced our
capacity to explore the universe’s most extreme and dynamic sector. In the mHz
frequency range, a diverse range of compact objects, from the most massive
black holes at the farthest reaches of the Universe to the lightest white
dwarfs in our cosmic backyard, generate a complex and dynamic symphony of
gravitational wave signals. Once recorded by gravitational wave detectors,
these unique fingerprints have the potential to decipher the birth and growth
of cosmic structures over a wide range of scales, from stellar binaries and
stellar clusters to galaxies and large-scale structures. The TianQin
space-borne gravitational wave mission is scheduled for launch in the 2030s,
with an operational lifespan of five years. It will facilitate pivotal insights
into the history of our universe. This document presents a concise overview of
the detectable sources of TianQin, outlining their characteristics, the
challenges they present, and the expected impact of the TianQin observatory on
our understanding of them.
