SUMMARY
The derivation of the quadrupole moment in the transverse traceless (TT) gauge for gravitational waves is essential for understanding gravitational radiation. The formula provided, QijTT(x) = ∫ρ(xixj-1/3δijr2)d3x, represents the reduced quadrupole moment, which is the trace-free component of the quadrupole moment. This derivation is commonly found in standard general relativity texts, confirming its foundational role in the study of gravitational waves. For further reading, the resource by Carroll offers a comprehensive explanation of this topic.
