The Universe has entered an accelerating expansion phase in the last few billion years of its evolution, a phenomenon that is caused by the mysterious entity known as dark energy. 
Through the NEVO project, I aim to provide key insights about the properties of dark energy, which includes its time evolution and spatial distribution in the Universe. This objective will be achieved by utilizing cutting-edge cosmological N-body simulations and novel techniques to study cosmic evolution accurately.
In this presentation, I will go into detail about the NEVO proposal and discuss its challenges in depth.

The animation below demonstrates how dark energy and matter cluster in a universe where the k-essence field is the candidate for dark energy. This clustering of dark energy affects structure formation and leaving distinct imprints that can be observed through future galaxy surveys like the Euclid satellite.
