In the following months, the Vera Rubin Observatory will start collecting data from the cosmos. The Dark Energy Science Collaboration (DESC) will study the cosmological implications of the new data focusing in the nature of the dark energy. In particular it will use five probes, namely supernovae, galaxy clusters, large-scale structure, and weak and strong gravitational lensing. The Mexican team LSST-Mexico has gained data rights thanks to an in-kind contribution program, allowing several Mexican scientists to work with the different science collaborations in LSST. Two teams are currently working at different subjects in DESC. I will give an overview of the expected science that will be obtained from this new data.
