Extreme-mass-ratio burst detection with TianQin

The capture of compact objects by massive black holes in galaxies or dwarf will generate short gravitational wave signals, called extreme-mass-ratio bursts (EMRBs), before evolving into inspirals. Their detection provide an investigation the hole properties and shed light on astronomy astrophysics. In this work, we investigate number TianQin observatory EMRBs. Our result shows that can detect tens EMRBs events during its mission lifetime. For those detected events, use Fisher information matrix to quantify these uncertainties inference their parameters. We consider possible network $\mathrm{TianQin}+\mathrm{LISA}$, study how a improve parameter estimation. that, for most sources, object mass, spin be determined with precision order ${10}^{\ensuremath{-}1}$ sky localization 10 square degree. further explore background generated unsolved conclude it is about ${10}^{6}$ times weaker than TianQin's sensitivity, thus ignored.
