abstract
Extreme Mass Ratio Inspirals (EMRIs) can be classified as dry EMRIs and wet EMRIs based on their formation mechanisms. Dry (or the "loss-cone") EMRIs, previously considered as the main EMRI sources for the Laser Interferometer Space Antenna, are primarily produced by multi-body scattering in the nuclear star cluster and gravitational capture. In this work, we highlight an alternative EMRI formation channel: (wet) EMRI formation assisted by the accretion flow around accreting galactic-center massive black holes (MBHs). In this channel, the accretion disk captures stellar-mass black holes that are intially moving on inclined orbits, and subsequently drives them to migrate towards the MBH - this process boosts the formation rate of EMRIs in such galaxies by orders of magnitude. Taking into account the fraction ($\mathcal O(10^{-2}-10^{-1})$) of active galactic nuclei where the MBHs are expected to be rapidly accreting, we forecast that wet EMRIs will contribute an important or even dominant fraction of all detectable EMRIs by spaceborne gravitational wave detectors.

Secondary spins of extreme mass ratio inspirals: A probe to the formation channels
For eccentric and inclined extreme mass-ratio inspirals, the secondary black hole spin may be measurable to about 0.1 at SNR 20, and high spins would point to the Hills formation channel.

Environmental effects in extreme mass ratio inspirals: perturbations to the environment in Kerr
A perturbative calculation shows that a secondary body in Kerr spacetime creates a wake in a superradiant scalar cloud, with energy fluxes that differ from Schwarzschild predictions by tens of percent.

Extreme mass-ratio inspiral within an ultralight scalar cloud I. Scalar radiation
Scalar radiation from an EMRI in an ultralight scalar cloud is computed semi-analytically, showing dipole clouds decelerate and quadrupole clouds accelerate the inspiral, with up to about 100 rad dephasing after 18 months.

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.

The fate of EMRI-IMRI pairs in AGN accretion disks: hydrodynamic and three body simulations
A small black hole near an intermediate-mass black hole in an AGN disk is usually captured into a merger or ejected, and both paths yield two successive EMRI/IMRI events.

Probing near-zone magnetic fields with extreme mass-ratio inspirals
A magnetized Schwarzschild background shifts EMRI orbital dynamics and GW waveforms, with B~10^9 G producing ~1.3 rad dephasing over one year for a 10^6 M_sun system.

Gravitational Atoms and Black Hole Binaries
A boson cloud around a black hole efficiently ionizes when a binary companion inspirals, and the resulting energy loss plus resonant eccentricity and inclination preferences create detectable gravitational-wave signat...
