Dark Matter with N-Body Numerical Simulations
Jazhiel Chacon, J. Alberto Vazquez, Ruslan Gabbasov
The development of numerical N -body simulations have allowed to study formation process and evolution of galaxies at different scales. This paper presents the fundamental concepts…
Graduated dark energy: Observational hints of a spontaneous sign switch in the cosmological constant
Ozgur Akarsu, John D. Barrow, Luis A. Escamilla +1
We study the cosmological constant () in the standard CDM model by introducing the \textit{graduated dark energy} (gDE) characterised by a minimal dynamical deviation from th…
Scalar Field Dark Matter Spectator During Inflation: The Effect of Self-interaction
Luis E. Padilla, J. Alberto Vázquez, Tonatiuh Matos +1
Nowadays cosmological inflation is the most accepted mechanism to explain the primordial seeds that led to the structure formation observed in the Universe. Current observations ar…
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: double-probe measurements from BOSS galaxy clustering \& Planck data -- towards an analysis without informative priors
Marcos Pellejero-Ibanez, Chia-Hsun Chuang, J. A. Rubiño-Martín +28
We develop a new methodology called double-probe analysis with the aim of minimizing informative priors in the estimation of cosmological parameters. We extract the dark-energy-mod…
