The nuclear symmetry energy and its slope $L$ are fundamental quantities describing the properties of dense matter around nuclear saturation.
New measurements of the neutron-skin thickness of $^{208}\rm Pb$ have sparked recent interest in constraints on the slope of the symmetry energy, $L$, some of which can also be inferred from astrophysical systems, such as neutron star mergers.

In this talk, I will present the first systematic study of the impact of varying $L$ on the post-merger evolution of a GW170817-like neutron star merger event. More specifically, I will discuss how different values of $L$ affect the post-merger dynamics, what imprints $L$ might leave in the post-merger gravitational wave signal and how the ejection of mass during the merger is affected by it.
