Abstract : Black hole binaries in non-circular orbits are astrophysically relevant sources for the operational hecto-Hz and rapidly maturing nano-Hz gravitational wave observatories. I will summarize our on-going efforts to develop computationally efficient inspiral-merger-ringdown waveform families, both in the time and frequency domains. How we adapted these efforts to model Pulsar Timing Array signals due to gravitational waves from inspiraling supermassive black hole binaries in relativistic eccentric orbits will be explained. Additionally, a brief description of our on-going efforts to model and search for gravitational wave burst signals, associated with compact binaries in relativistic hyperbolic/ parabolic orbits will be presented.
