| Outline of Annual Research Achievements |
I was able to push forward my research on massive gravity.
In particular in these last three years, I have been understanding more and more the phenomenology of Lorentz breaking massive gravity theories.
I have applied a crucial feature of this theory, namely the fact that it leads to weak gravity interactions, to fit actual data.
The answer was really amazing: I have found that this theory is able to fit the redshift space distortion data better than the standard model for cosmology.
If this trend in the data continues in future experiments, then massive gravity theories could be regarded as a strong candidate to explain how gravity work at large scales.
Furthermore, I have started investigating, together with my collaborators, new modified gravity theories which look very promising.
