We simulate the expected variations of background flux at two particular sites of the Latin American Giant Observatory (LAGO) and found that these fluxes are sensible to the latitude and that neutrons and muons components, of cosmic rays, are affected due to the variation of the geomagnetic field (GF).
We describe the experience of running an Astrophysics outreach initiative involving traditional mass media like radio broadcast and new digital media like blog, microblogging and internet video channel. Some very successful preliminary results are also presented. This unique experience is helping to create new science informal education environments for Spanish speaking people in Latin America.
Using the concept of cracking, we have explored the influence of density fluctuations on isotropic and anisotropic charged matter configurations in General Relativity with "barotropic" equations of state, $P = P(ρ)$ and $P_{\perp}= P_{\perp}(ρ)$ and a mass-charge relation $Q=Q(ρ)$. We have refined the idea that density fluctuations affect physical variables and their gradients, i.e. the radial pressure and charge density gradients. It is found that not only anisotropic charged models could present cracking (or overturning), but also isotropic charged matter configurations could be affected by density fluctuations.
