We study the gravitational wave (GW) phase shift arising from center-of-mass accelerations of binary black hole mergers formed dynamically in three-body systems, where both the inner orbit of the merging binary and the outer orbit are eccentric. We provide a semi-analytical model and several analytical approximations that allow for fast evaluation of both the temporal evolution and the maximum value of the phase shift. The highest phase shifts occur when the binary merges close to the pericentre of the outer orbit, and can in this case be orders-of-magnitude larger compared to the circular limit. At high outer orbit eccentricities, the orbital curvature leaves distinct imprints onto the phase shift if the binary passes the outer pericentre during its inspiral. By comparing with phase shifts measured in numerical chaotic 3-body scatterings, we show that our model accurately describes the observed phase of dynamically assembled binary systems in realistic astrophysical scenarios, providing a way to directly determine their formation channel via single GW observations.

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.

Environmental effects in stellar mass gravitational wave sources II: Enhanced detectability of phase shifts in eccentric sub-populations
Eccentricity boosts the detectability of environmental dephasing in gravitational-wave signals by up to ℓ_max^{1-n}, potentially making environmental effects ubiquitous in future detectors' eccentric sources.

The Proper Motion of Strongly Lensed Binary Neutron Star Mergers in LIGO/Virgo/Kagra can be Constrained by Measuring Doppler Induced Gravitational Wave Dephasing
Doppler dephasing between the two images of a strongly lensed neutron-star merger could be detectable at LIGO A+ and A# sensitivity for relative transverse velocities of roughly 1,800 to 2,000 km/s.

Detection of Intermediate-Mass Ratio Inspirals in Globular Clusters: Revealing the Brownian Motion with Gravitational Waves
Brownian motion from stellar encounters in globular clusters imprints Doppler and aberrational phase shifts on IMRI gravitational waves that should be detectable for most sources loud enough for TianQin, LISA, or AION to see.

Constraining Proper Motion of Strongly Lensed Eccentric Binary Mergers using Doppler Triangulation
Doppler-induced GW phase shifts between lensed images of eccentric binaries grow with time only until e about 0.7, then decline, giving a factor of about 2 boost over circular sources at the same frequency.
