The dark matter transfer function: free streaming, particle statistics and memory of gravitational clustering
D. Boyanovsky, H. J. de Vega, N. Sanchez
The transfer function of dark matter (DM) perturbations during matter domination is obtained by solving the collisionless Boltzmann-Vlasov equation. We find an \emph{exact}…
MCMC analysis of WMAP3 and SDSS data points to broken symmetry inflaton potentials and provides a lower bound on the tensor to scalar ratio
C. Destri, H. J. de Vega, N. G. Sanchez
We perform a MCMC (Monte Carlo Markov Chains) analysis of the available CMB and LSS data (including the three years WMAP data) with single field slow-roll new inflation and chaotic…
New Inflation vs. Chaotic Inflation, Higher Degree Potentials and the Reconstruction Program in light of WMAP3
D. Boyanovsky, H. J. de Vega, C. M. Ho +1
The CMB power spectra are studied for different families of single field new and chaotic inflation models in the effective field theory approach to inflation. We implement a system…
Statistical Mechanics of the self-gravitating gas: thermodynamic limit, phase diagrams and fractal structures
H. J. de Vega, N. Sanchez
We provide a complete picture to the self-gravitating non-relativistic gas at thermal equilibrium using Monte Carlo simulations, analytic mean field methods (MF) and low density ex…
Primordial magnetic fields from cosmological phase transitions
D. Boyanovsky, H. J. de Vega, M. Simionato
We study the generation of large scale primordial magnetic fields by a cosmological phase transition during the radiation dominated era. The setting is a theory of N charged scalar…
Extreme Energy Cosmic Rays: Bottom-up vs. Top-down scenarii
H. J. de Vega, N. Sanchez
We present an overview on extreme energy cosmic rays (EECR) and the fundamental physics connected with them. The top-down and bottom-up scenarii are contrasted. We summarize the es…
