Description
Most searches for continuous gravitational waves (CGWs) from individual supermassive black hole binaries (SMBHBs) in pulsar timing array (PTA) data assume circular orbits, despite theoretical studies suggesting that these sources may retain significant eccentricity. In this talk, I will present QuickGWecc, a fast and efficient Bayesian pipeline for searching for CGWs from SMBHBs in relativistic eccentric orbits, extending the QuickCW framework. By exploiting the separation between projection and shape parameters, the method achieves orders-of-magnitude computational speedups, making eccentric searches tractable. I will show validation results using simulated datasets and discuss its prospects for application to upcoming PTA datasets.
