Constraining Newtonian stellar configurations in f(R) theories of gravity
T. Multamaki, I. Vilja
We consider general metric theories of gravity by solving the field equations in the presence of a spherical static mass distribution by analytical perturbative means. Expan…

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…

Non-Gaussianity from Preheating
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We consider a two-field model for inflation where the second order metric perturbations can be amplified by a parametric resonance during preheating. We demonstrate that there can…
