The effect of matter discreteness on gravitational wave propagation in post-geometrical optics
Sena Atli, Syksy Rasanen
The gravitational wave equation of motion includes direct coupling to the Riemann tensor. The curvature terms are usually neglected, but they can be large at the location of matter…

Higgs- inflation -- full slow-roll study at tree-level
Vera-Maria Enckell, Kari Enqvist, Syksy Rasanen +1
We consider Higgs inflation with an term. It adds a new scalar degree of freedom, which leads to a two-field model of inflation. We do a complete slow-roll analysis of the t…

Microwave sky and the local Rees-Sciama effect
Aleksandar Rakic, Syksy Rasanen, Dominik J. Schwarz
The microwave sky shows unexpected features at the largest angular scales, among them the alignments of the dipole, quadrupole and octopole. Motivated by recent X-ray cluster studi…
