Description
The search for the non-linear memory effect, which is a permanent strain in spacetime that remains after the passage of a gravitational wave (GW), has been ongoing in PTA data for years, using a simple burst model. With the upcoming IPTA-DR3, a working group has been formed to research memories (both linear and nonlinear). In this talk, we will present the preliminary work carried out to search for a realistic model of nonlinear memory in PTA data.
