Constraining SUSY GUTS with Cosmology
Mairi Sakellariadou, Jonathan Rocher
Cosmic strings of the GUT scale, generically formed during the SSB of supersymmetric hybrid inflation, are compatible with the most recent CMB data. The strong constraints on the a…
Genericity of Cosmic Strings Formation in SUSY GUTs
J. Rocher, R. Jeannerot, M. Sakellariadou
The idea of GUT implies that the universe went through a series of phase transitions during which topological defects are expected to form. We investigate here the genericity of co…
Consistency of cosmic strings with cosmic microwave background measurements
Jonathan Rocher, Mairi Sakellariadou
In the context of SUSY GUTs, GUT scale cosmic strings formed at the end of hybrid inflation are compatible with currently available CMB measurements. The maximum allowed cosmic str…
The role of topologigal defects in cosmology
Mairi Sakellariadou
Topological defects are involved in a plethora of physical and astrophysical phenomena. In these lectures, I will review the r\^ ole they could play in the large-scale structure fo…
Seeds of Large Scale Anisotropy in Pre-Big-Bang Cosmology
Mairi Sakellariadou
Within a string cosmology context, the large scale temperature anisotropies may arise from the contribution of seeds to the metric fluctuations. We study the cases of electromagnet…
Spectrum of Cosmological Perturbations from Multiple-Stage Inflation
Mairi Sakellariadou, Nikos Tetradis
Within the context of supersymmetric hybrid inflation, we study a multiple-stage inflationary scenario that can generate a primordial spectrum of adiabatic density perturbations wi…
