Cosmic strings are one‐dimensional topological defects which could have been formed in the early stages of our Universe. They triggered a lot of interest, mainly for their cosmological implications: they could offer an alternative to inflation for the generation of density perturbations. It was shown however that cosmic strings lead to inconsistencies with the measurements of the cosmic microwave background temperature anisotropies. The picture has changed recently. It was shown that, on the… 
Cosmic Strings
Cosmic strings, a hot subject in the 1980’s and early 1990’s, lost its appeal when it was found that it leads to inconsistencies in the power spectrum of the measured cosmic microwave background
Production of Topological Defects at the End of Inflation
Cosmological inflation and topological defects have been considered for a long time, either in disagreement or in competition. On the one hand an inflationary era is required to solve the
Finite temperature corrections and embedded strings in noncommutative geometry and the standard model with neutrino mixing
The recent extension of the standard model to include massive neutrinos in the framework of noncommutative geometry and the spectral action principle involves new scalar fields and their interactions
Theoretical and observational constraints on brane inflation and study of scalar perturbations through the effective field theory formalism
In this thesis, consisting of two main parts, we study observational signatures of cosmic (super)strings in the context of D-brane inflation and properties of scalar perturbations on generic
D-term inflation in non-minimal supergravity
D-term inflation is one of the most interesting and versatile models of inflation. It is possible to implement naturally D-term inflation within high energy physics, as for example supersymmetry
Neutrinos and dark energy
From the observed late-time acceleration of cosmic expansion arises the quest for the nature of Dark Energy. As has been widely discussed, the cosmic neutrino background naturally qualifies for a
Probing neutrino dark energy with extremely high energy cosmic neutrinos
Recently, a new non-standard-model neutrino interaction mediated by a light scalar field was proposed, which renders the big bang relic neutrinos of the cosmic neutrino background a natural dark
General relativistic density perturbations
We investigate a general relativistic mechanism in which spikes generate matter overdensities in the early universe. When the cosmological fluid is tilted, the tilt provides another mechanism in
Probing primordial stochastic gravitational wave background with multi-band astrophysical foreground cleaning
The primordial stochastic gravitational wave background (SGWB) carries first-hand messages of early-universe physics, possibly including effects from inflation, preheating, cosmic strings,


D-term inflation without cosmic strings.
A superstring-inspired version of D-term inflation that does not lead to cosmic string formation and appears to satisfy the current cosmic microwave background constraints and is expected to survive supergravity corrections.
Cosmic superstring gravitational lensing phenomena: Predictions for networks of ( p , q ) strings
The unique, conical space-time created by cosmic strings brings about distinctive gravitational lensing phenomena. The variety of these distinctive phenomena is increased when the strings have
How generic is cosmic string formation in supersymmetric grand unified theories
We study cosmic string formation within supersymmetric grand unified theories (GUTs). We consider gauge groups having a rank between 4 and 8. We examine all possible spontaneous symmetry breaking
Collisions of cosmic F- and D-strings
Recent work suggests that fundamental and Dirichlet strings, and their (p,q) bound states, may be observed as cosmic strings. The evolution of cosmic string networks, and therefore their
Gravitational radiation from cosmic (super)strings: Bursts, stochastic background, and observational windows
The gravitational wave (GW) signals emitted by a network of cosmic strings are reexamined in view of the possible formation of a network of cosmic superstrings at the end of brane inflation. The
D-term inflation, cosmic strings, and consistency with cosmic microwave background measurements.
Using current CMB measurements, the free parameters (gauge and superpotential couplings, as well as the Fayet-Iliopoulos term) of D-term inflation are constrained.
