Abstract

The LVK collaboration has detected over 90 gravitational wave (GW) events till the end of the third observing run (O3) of LIGO and Virgo detectors. The gravitational waveforms used till O3 did not include the effect of eccentricity, but as we move towards higher detection rates, we may expect to detect eccentric binary systems. Using the eccentric hybrid waveforms constructed by our group, we perform some injection studies to show that analyzing eccentric systems with circular models can lead to significant biases in the intrinsic parameters. Further, using the eccentric models currently available, we quantify the detection rates of eccentric binaries in the observing runs for current and future ground-based GW detectors.
