DOI: 10.1088/1361-6382/adf02b
Abstract: We outline a practical scheme for converting between three commonly used sets of phases to describe the trajectories of extreme mass ratio inspirals; quasi-Keplerian (QK) angles, Mino time (MT) action-angles, and Boyer–Lindquist (BL) time action-angles… read more here.

DOI: 10.1093/mnras/sty1079
Abstract: Extreme-mass-ratio-inspiral observations from future space-based gravitational-wave detectors such as LISA will enable strong-field tests of general relativity with unprecedented precision, but at prohibitive computational cost if existing statistical techniques are used. In one such test… read more here.

DOI: 10.1103/physrevd.104.084011
Abstract: Extreme-mass-ratio inspirals (EMRIs), compact binaries with small mass-ratios 1, will be important sources for low-frequency gravitational wave detectors. Almost all EMRIs will evolve through important transient orbital rθ-resonances, which will enhance or diminish their gravitational… read more here.
