PODEMOS SER COMPETITIVOS EN I+D+i , también ahora (Análisis de un caso de éxito: ASTROFÍSICA ESPAÑOLA) Francisco Sánchez Foro España Innova, 6/2/2012 No voy a hablarles esta mañana ni de planetas extrasolares, ni de estrellas de neutrones, agujeros negros, materia obscura, energía obscura, ni de ninguna otra maravilla del misterioso Universo al que pertenecemos. Tampoco es mi intención hacer un discurso apologético, resaltando los mil y un beneficios de la Ciencia y del poder de la investigación para promover la competitividad y la recuperación económica, (todos los aquí presentes ya lo

Informe Semanal ha viajado al Instituto de Astrofísica de Canarias para conocer los últimos proyectos que nos acercan más al Sol.

La colaboración SDSS-III, en la que participa el IAC, anuncia nuevos resultados del proyecto BOSS sobre la enigmática energía oscura y los neutrinos, las elusivas partículas subatómicas claves para entender tanto el origen del universo como las supernovas

Stars are generally spherical, yet their gaseous envelopes oftenappear non-spherical when ejected near the end of their lives. Thisquirk is most notable during the planetary nebula phase when theseenvelopes become ionized. The most popular explanation is that theasymmetry, and in particular the formation of highly collimatedstructures such as the precessing jets observed in a number ofnebulae, is caused by interactions in a binary system. The study ofthe prototypical planetary nebula Fleming 1 with the VLT telescopedemonstrates for the first time that the hypothesis iscorrect. Indeed, it is

We present observational evidence of apparent plasma rotational motions in the feet of a solar prominence. Our study is based on spectroscopic observations taken in the \ion{He}{1}~1083.0~nm multiplet with the Tenerife Infrared Polarimeter attached to the German Vacuum Tower Telescope. We recorded a time sequence of spectra with 34 s cadence placing the slit of the spectrograph almost parallel to the solar limb and crossing two feet of an intermediate size, quiescent {\it hedgerow} prominence. The data show opposite Doppler shifts, $\pm$~6\kms, at the edges of the prominence feet. We argue

The old, red stars that constitute the bulges of galaxies, and the massive black holes at their centres, are the relics of a period in cosmic history when galaxies formed stars at remarkable rates and active galactic nuclei (AGN) shone brightly as a result of accretion onto black holes. It is widely suspected, but unproved, that the tight correlation between the mass of the black hole and the mass of the stellar bulge results from the AGN quenching the surrounding star formation as it approaches its peak luminosity. X-rays trace emission from AGN unambiguously, whereas powerful star-forming
