We have studied the spatial structure of the three dimensional large-scale pattern of the Galactic Magnetic Field using the polarization maps obtained by the WMAP satellite at 22 GHz. By using different models of the large-scale magnetic field of the Milky Way and a certain model for the cosmic rays electron distribution, we predict the expected

We present a study that links the Number Counts (NCs) to the rest-frame luminosity functions (LFs) at the passbands probed by the observed K-band at different epochs. Making use of a large K-band selected sample in the Groth Field, HDFN and CDFS ( ˜ 0. 27 deg2), we have derived highly reliable photometric redshift estimates that allow us to

We present the scheme developed for the quick analysis and data quality checks on the MAGIC Cherenkov Telescope at La Palma. Due to its low energy threshold MAGIC acquires data of atmospheric showers at a rate of more than 200Hz, which translates in up to 700GB per night. A fast On-Site data reduction is needed to detect hardware problems and in

We present results on the cosmic evolution of the outskirts of disk galaxies. In particular we focus on galaxies with stellar disk truncations. Using UDF, GOODS and SDSS data we show how the position of the break evolves with time since z ˜ 1. Our findings agree with an evolution on the radial position of the break by a factor of 1.3 ± 0.14 in the

Este artículo presenta algunas reflexiones en torno a la popularización de la Ciencia, desarrolladas a lo largo de mi trayectoria profesional, un camino inacabado desde la intuición al oficio. Tras revisar las señas de identidad de la divulgación científica, se exponen ideas, experiencias y recursos, cribados por la práctica y su posterior análisis

Extremely Large Telescopes are very challenging concerning their Adaptive Optics requirements. Their diameters, the specifications demanded by the science for which they are being designed for, and the planned use of Extreme Adaptive Optics systems, imply a huge increment in the number of degrees of freedom in the deformable mirrors. It is
