A survey is made of the evidence for and against the hypothesis that cosmic rays affect cloud cover and thereby surface temperature. The analysis is made for...
Cosmic rays and climate: The influence of cosmic rays on terrestrial clouds and global warming
We analyse the new ISCCP (International Satellite Cloud Climatology Project) D2 cloud data to ascertain if a connection between cosmic-ray flux and cloud cover...
This book contains the lectures delivered at the XIII Canary Islands Winter School of Astrophysics, which reviewed current knowledge about the origin and...
The chemical composition of the Universe has evolved over billions of years. A host of astrophysical processes and observations must be understood in order to...
"CosmoLAB" is an educational project with the goal of bringing Astronomy and, in particular, the practice of astronomical observation, closer to the educational...
The determination of the fundamental cosmological parameters has achieved dramatic progress over the past few years. Using Cepheids and secondary distance...
Cosmological parameters and non-vacuum initial states
A class of spatially flat models with a cosmological constant and a primordial broken scale invariant (BSI) spectrum of adiabatic perturbations is confronted...
