We study the evolution of eccentric, equatorial extreme-mass-ratio inspirals (EMRIs) immersed in the accretion disks of active galactic nuclei. We find that single gravitational-wave observations from these systems could provide measurements with ~ 10 % relative precision of, simultaneously, the disk viscosity and mass accretion rate of the central supermassive black hole. This is possible when the EMRI transitions, within the observation time, from supersonic to subsonic motion relative to the disk gas, for eccentricities e > ~ 0.025-0.1. The estimate of the accretion rate would assist in the identification of the EMRI's host galaxy, or the observation of a direct electromagnetic counterpart, improving the chances of using these sources as cosmological sirens. Our work highlights the rich phenomenology of binary evolution in astrophysical environments and the need to improve the modelling and analysis of these systems for future gravitational-wave astronomy.

Dissecting environmental effects with eccentric gravitational wave sources
Resonances between oscillating environmental forces and the epicyclic motion of eccentric binaries can dominate gravitational wave dephasing over orbit-averaged drag for eccentricities above about 0.05.

Sequential simulation-based inference for extreme mass ratio inspirals
Sequential simulation-based inference with truncated marginal neural ratio estimation shrinks the 11-parameter search volume for simulated non-spinning extreme-mass-ratio inspirals by factors of 1e6 to 1e7 and recover...

The implications of stochastic gas torques for asymmetric binaries in the LISA band
Hydrodynamic stochastic gas torques do not bias the recovered binary parameters of EMRI/IMRI signals in LISA, but they can bias or hide the inferred accretion disk torque amplitude and slope.

Eccentricity-Modulated Phase Degeneracy and Distinguishability between Dark Matter and Accretion Disk Environmental Effects in EMRIs
DM dephasing in EMRIs is nearly eccentricity-independent while disk dephasing is strongly suppressed by e0, so residual SNR and distinguishability time favor slightly eccentric orbits for LISA separation of the two effects.

When vacuum breaks: a self-consistency test for astrophysical environments in extreme mass ratio inspirals
A duration-scan self-consistency test on vacuum EMRI parameter posteriors flags unmodeled environmental effects without adding environmental parameters.

Extreme mass-ratio inspirals and extra dimensions: Insights from modified Teukolsky framework
A modified Teukolsky equation and the Dudley-Finley approximation give nearly the same LISA detectability bound for the braneworld tidal charge, with MTE mismatches growing faster for high-eccentricity EMRIs.
