Static spherically symmetric perfect fluid solutions in theories of gravity
T. Multamaki, I. Vilja
Static spherically symmetric perfect fluid solutions are studied in metric theories of gravity. We show that pressure and density do not uniquely determine ie. given…

Suppression of the large scale curvature perturbation by interacting fluids
T. Multamaki, J. Sainio, I. Vilja
The large-scale dynamics of a two-fluid system with a time dependent interaction is studied analytically and numerically. We show how a rapid transition can significantly suppress…

Spherically symmetric solutions of modified field equations in f(R) theories of gravity
Tuomas Multamaki, Iiro Vilja
Spherically symmetric static empty space solutions are studied in f(R) theories of gravity. We reduce the set of modified Einstein's equations to a single equation and show how one…
