In 2022 we published a Nature Astronomy (High Impact Journal) using the constrained simulations technique that I described in the proposalM. Ata et al. Nature Astronomy 6 (2022) 857. This was a great success and showed that the method of 'constrained simulations' is capable reproducing observed structures and even model them into the future.We were able to reproduce the observed structures within our simulations and also predict their future fate by moving the simulation until today. This resembles a predicted future fate of these structures by a total of 11 billion years. At the final time step we analyzed the resulting structures so that we were able to trace back all constituent dark matter particles that belong to this final collapsed object. This was the first application of a constrained simulations on a lightcone.As stated in my proposal, I will use this technique to predict the creation of gravitational wave events.　After a more thoroughly literature research, I came to the conclusion that a limited patch at high redshifts, like we analyzed in the 2022 paper, is not the ideal environment. Also, I re-elaborated the framework and found an application that is more suited to our constrained maps.
