On the catastrophe time of fluids under the action of a gravitational field
D. Astesiano, G. Ortenzi, M. L. Ruggiero
Motivated by the central role of the Zel'dovich approximation in the description of cosmic structure formation through gravitational collapse, we investigate Burgers-type dynamics…

Rigid rotation in GR and a generalization of the virial theorem
Davide Astesiano
In this work we study the properties of rigidly rotating neutral dust solutions in general relativity. This class of solutions gained relevance recently due to applications to the…

Towards a full general relativistic approach to galaxies
Davide Astesiano, Sergio L. Cacciatori, Federico Re
We analyze the dynamics of a single spiral galaxy from a general relativistic viewpoint. We employ the known family of stationary axially-symmetric solutions to Einstein gravity co…
