Constraints on Kinetically Modified Inflation from WMAP5
Larissa Lorenz, Jerome Martin, Christophe Ringeval
Single field inflationary models with a non-minimal kinetic term (also called k-inflationary models) can be characterised by the so-called sound flow functions, which complete the…
K-inflationary Power Spectra in the Uniform Approximation
Larissa Lorenz, Jerome Martin, Christophe Ringeval
The advent of explicit Dirac-Born-Infeld (DBI) inflationary models within string theory has drawn renewed interest to the cosmological role of unusual scalar field dynamics, usuall…
Small-Angle CMB Temperature Anisotropies Induced by Cosmic Strings
Aurélien A. Fraisse, Christophe Ringeval, David N. Spergel +1
We use Nambu-Goto numerical simulations to compute the cosmic microwave background (CMB) temperature anisotropies induced at arcminute angular scales by a network of cosmic strings…
The exact numerical treatment of inflationary models
Christophe Ringeval
The precision reached by the recent CMB measurements gives new insights into the shape of the primordial power spectra of the cosmological perturbations. In the context of inflatio…
Inflation after WMAP3: Confronting the Slow-Roll and Exact Power Spectra with CMB Data
Jerome Martin, Christophe Ringeval
The implications of the WMAP (Wilkinson Microwave Anisotropy Probe) third year data for inflation are investigated using both the slow-roll approximation and an exact numerical int…
Cosmological evolution of cosmic string loops
Christophe Ringeval, Mairi Sakellariadou, Francois Bouchet
The existence of a scaling evolution for cosmic string loops in an expanding universe is demonstrated for the first time by means of numerical simulations. In contrast with what is…
