There is some weak evidence that the black hole merger named GW190521 had a non-zero eccentricity. In addition, the component black holes' masses exceeded the limit predicted by stellar evolution. The large masses can be explained by successive mergers, which may be efficient in gas disks surrounding active galactic nuclei (AGN), but it is difficult to maintain an eccentric orbit all the way to the merger, as basic physics would argue for circularization. Here we show that AGN-disk environments can lead to an excess of eccentric mergers, if the interactions between single and binary black holes are frequent, and occur with mutual inclinations of less than a few degrees. We further illustrate that this eccentric population has a different distribution of the inclination between the spin vectors of the black holes and their orbital angular momentum at merger, referred to as the spin-orbit tilt, compared to the remaining circular mergers.

Stable mass transfer in massive binaries leading to merging black holes
Stable mass transfer in massive binaries, modeled with the accreting star's altered structure, produces merging black holes matching LIGO/Virgo masses and spins.

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.

Inferring the stochastic gravitational-wave background from eccentric stellar-mass binary black holes with spaceborne detectors
Eccentric black-hole-binary backgrounds from globular clusters and isolated evolution would look like power-law noise for TianQin/LISA/Taiji, but AGN-formed binaries produce a turnover that LISA and Taiji can distinguish.

Eccentricity Effects on Modeling Dynamic Quantities and Their Correlations in Binary Black Hole Mergers
Varying the initial orbital phase of an eccentric binary black hole at fixed eccentricity produces an envelope of radiated energy, momentum, and spin, so eccentric mergers span broad domains of remnant properties rela...
