DOI: 10.1007/s10714-017-2261-4
Abstract: We consider the problem of constructing cosmological solutions of the Einstein–Maxwell equations that contain multiple charged black holes. By considering the field equations as a set of constraint and evolution equations, we construct exact initial… read more here.

DOI: 10.1007/s10773-018-3856-6
Abstract: Christodoulou and Rovelli have revealed that black holes have big interiors that grow asymptotically linearly with advanced time. Even if the Hawking radiation is taken into account, such interiors remain large. Based on these findings,… read more here.
