Scalar field description of a parametric model of dark energy
Scalar field description parametric model dark energy
2011/10/9
We investigate theoretical and observational aspects of a time-dependent parameterization for the dark energy equation of state (EoS) $w(z)$, which is a well behaved function of the redshift $z$ over ...
Minimally Parametric Power Spectrum Reconstruction from the Lyman-alpha Forest
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
Current results from the Lyman alpha forest assume that the primordial power spectrum of density perturbations follows a simple power law form. We present the first analysis of Lyman alpha data to stu...
Modeling the evolution of infrared galaxies: A Parametric backwards evolution model
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We aim at modeling the infrared galaxy evolution in an as simple as possible way and reproduce statistical properties among which the number counts between 15 microns and 1.1 mm, the luminosity functi...
Multi-parametric Effect of Solar Activity on Cosmic Rays
Sun solar parameters cosmic ray modulation running multiple correlation method
2010/9/16
The long-term modulation of cosmic ray intensity (CRI) by different solar activity (SA) parameters and an inverse correlation between individual SA parameter and CRI is well known. Earlier, it has bee...
Parametric Identification of Solar Series based on an Adaptive Parallel Methodology
Sunspot time series system identification parametric modelling optimization parallelism adaptation
2009/5/12
In this work we present an adaptive parallel methodology
to optimize the identification of time series through parametric models,
applying it to the case of sunspot series. We employ high precision
...
