Probing beyond-vacuum general relativistic effects with extreme mass-ratio inspirals
Tieguang Zi, Mostafizur Rahman, Shailesh Kumar
We examine extreme mass-ratio inspirals (EMRIs) as probes of beyond-vacuum general relativistic effects, accounting for both astrophysical environments and scalar Gauss-Bonnet (sGB…
Preliminary forecasting constraint on scalar charge with LISA in non-vacuum environments
Tieguang Zi, Chang-Qing Ye
We compute the gravitational wave signal from eccentric extreme-mass-ratio inspirals (EMRIs) embedded within beyond-vacuum environments, where the secondary object carries a scalar…
Constraint on massive vector field with extreme-mass-ratio inspirals around a slowly rotating black hole
Tieguang Zi, Peng-Cheng Li, Bao-Min Gu +1
We study the influence of a massive vector (Proca) field on the energy fluxes from extreme-mass-ratio inspirals (EMRIs) around a slowly rotating Kerr black hole. The secondary comp…
Eccentric extreme-mass-ratio inspirals: a new window into ultra-light vector fields
Tieguang Zi, Fu-Wen Shu
Space-based gravitational-wave detectors, such as the Laser Interferometer Space Antenna (LISA), provide a platform to probe new fundamental fields through extreme-mass-ratio inspi…
