How the expansion of the universe determines the causal structure of McVittie spacetimes
Alan M. da Silva, Michele Fontanini, Daniel C. Guariento
We present a theorem which allows one to recognize and classify the asymptotic behavior and causal structure of McVittie metrics for different choices of scale factor, establishing…

Realistic fluids as source for dynamically accreting black holes in a cosmological background
Daniel C. Guariento, Michele Fontanini, Alan M. da Silva +1
We show that a single imperfect fluid can be used as a source to obtain the generalized McVittie metric as an exact solution to Einstein's equations. The mass parameter in this met…
