Memory effect in LISA sources: prospects and relevance

Gravitational wave memory is a non-linear prediction of general relativity that informs us about the energy fluxes emitted by gravitational wave sources. Its detection is more challenging than the ordinary waveform and requires dedicated studies. On the other hand, the information in the memory is complementary to the main signal, and may even break some degeneracies of the latter, or probe new aspects of GR. In this talk, I will present the most recent analysis of how LISA can detect the GW memory, taking into account the most recent population models. Finally, I will discuss some implications for parameter estimation and future directions.
