| Outline of Annual Research Achievements |
During the last year I have worked on several aspects of the minimal theory of massive gravity (MTMG) and bigravity, two of the models that I have recently introduced together with my collaborators.
In the context of MTMG, I have attempted to search for a modification of gravity which could get a better fit to the data, and at the same time, to give some insight of how a viable theory of massive gravity might look like.
Since last April, I have written papers published in high‐impact‐factor peer‐reviewed journals. In particular, I have understood how MTMG can influence some Dark Energy data and proved that it can do a better fit with respect to the standard model of cosmology. Although other more precise data are necessary to further confirm MTMG these results are very promising.
