Dynamical analysis of a first order theory of bulk viscosity
Giovanni Acquaviva, Aroonkumar Beesham
We perform a global analysis of curved Friedmann-Robertson-Walker cosmologies in the presence of a viscous fluid. The fluid's bulk viscosity is governed by a first order theory rec…
Structure formation with causal bulk viscosity
Giovanni Acquaviva, Anslyn John, Aurélie Pénin
Dissipative features of dark matter affect its clustering properties and could lead to observable consequences for the evolution of large--scale structure. We analyse the evolution…
A gravitational energy-momentum and the thermodynamic description of gravity
Giovanni Acquaviva, David Kofroň, Martin Scholtz
A proposal for the gravitational energy-momentum tensor, known in the literature as the square root of Bel-Robinson tensor, is analyzed in detail. Being constructed exclusively fro…
