Radiation and Asymptotics for Spacetimes with Non-Isotropic Mass

In this talk, I will discuss some results on radiation, angular momentum at future null infinity and peeling for a general class of spacetimes.

We shall focus on the radiation field and asymptotics for asymptotically-flat solutions of the Einstein equations with a term homogeneous of degree -1 in the initial data metric, that is it may include a non-isotropic mass term. Moreover, antipodal symmetry and non-symmetry questions shall be addressed.
