More than 90 years ago, Einstein predicted the existence of Gravitational Waves as a consequence of his theory of General Relativity. They are minute distortions of space and time, created by rapidly accelerating large masses, and propagating at the speed of light. Several kilometer-size laser-interferometric gravitational wave detectors are currently operating on the earth. They will soon be...

LISA Pathfinder is a mission of the European Space Mission aimed at
demonstrating the space-time metrology required for space-borne
gravitational wave observatories like eLISA. In particular the mission aims
at experimentally test the detailed physical model of the eLISA instrument
using the hardware, which is going to be flown on eLISA. This model predicts
that no true forces on...

A first order phase transition in the early universe acts as a source of gravitational waves. The gravitational waves are produced by the collision of the broken phase bubbles and by the magnetohydrodynamic turbulence in the primordial plasma stirred by the bubble collision. It will be shown how the shape and amplitude of the gravitational wave spectrum can be predicted by general arguments...

If LHC finds no signatures of new physics (thus confirming the Standard Model) the necessity to explain the observed beyond-the-Standard-Model (BSM) phenomena, in particular neutrino
masses, Dark Matter and matter-antimatter asymmetry of the Universe, should largely shape the further development of particle physics. I will describe a unique testable approach that provides the resolution of...

We consider the implications of the $E_6$ inspired supersymmetric (SUSY) models with an additional $U(1)_N$ gauge symmetry under which right--handed neutrinos have zero charge for collider phenomenology and cosmology. To ensure anomaly cancellation and gauge coupling unification the low energy matter content of
these models involve three $27$ representations of $E_6$ and a pair of $SU(2)$...

The Planck satellite, selected by ESA in 1996, was launched in 2009 and delivered on March 21st 2013 its first full sky maps of the millimetric emission at 9 frequencies, and maps derived from them, in particular the map of the anisotropies of the Cosmic Microwave Background (CMB). I will briefly recall the characteristics of the Planck instruments, and describe the data processing performed...

I will discuss the recent LHC and Planck results, which both are completely compatible with the Standard model of particle physics, and Standard cosmological mode (LambdaCDM), respectively. I will discuss, that the extension of the Standard Model is, of course, required, but can be very minimal. The theoretically nicest extension should also be scale invariant. I will discuss what future...

The minimal F-term hybrid inflation model is defined by a unique renormalizable superpotential, fixed by a U(1) R-symmetry, and employs a minimal canonical Kaehler potential. The inflationary potential takes into account both radiative and supergravity corrections, as well as an important soft supersymmetry breaking term. With n_s in the vicinity of 0.96-0.97, as strongly indicated by the...

I will present forecasts for the accuracy of determining the parameters of a minimal LCDM and the total neutrino mass for a Euclid-like survey. To include as much information as possible, and use the midly non-linear scales in a meaningful way, I will present our method of including theoretical errors.
Two sets of errors are considered: (i) one to account for uncertainties in the modelling of...

We discuss how high-energy physics (in particular in the cases of loop corrections, particle production, Lorentz violation) affects the correlators of primordial cosmological perturbation, and how this would be reflected in observations. We study features such as the possibility of enhancements or oscillations, and analyze the sensitivity of observables to the scale of high-energy physics,...
