Testing spectral models for Stellar Populations High spectral resolution evolutionary synthesis models have become a routinely used ingredient in extragalactic work, and as such deserve thorough testing. Star clusters are ideal laboratories for such tests. In this talk I apply the spectral fitting methodology to a sample of clusters, mainly from the Magellanic Clouds and spanning a wide range in age and metallicity, fitting their integrated light spectra with a suite of modern evolutionary...

e-Ciencia de la A a la Z Al hablar de e-Ciencia es complicado no mencionar los Grids. Al hablar de Grid es fácil relacionar con computación. Pero podemos ampliar este concepto pues, al fin y al cabo, un Grid viene a ser una malla que conecta cosas. Estas cosas están distribuidas geográficamente e interconectadas en red. De esta forma podemos tener no solo Grids de computación, sino también de datos o instrumentos, e incluso...

Radio Supernovae: A Window into the Heart of Starburst Galaxies High-resolution radio observations of the nuclear regions of Luminous and Ultraluminous Infrared Galaxies (ULIRGs) have shown that their radio structure consists of a compact high surface-brightness central radio source inmersed in a diffuse low brightness circumnuclear halo. While the central components could be associated with AGNs or compact star-forming regions, where radio supernovae are exploding, it is well known that the circumnuclear... Antxón Alberdi |

Tracing dust at the edge of destruction: NIR observations of YSO transitional disks and nearby AGN with the Keck interferometer After a short introduction to modern infrared long baseline interferometry, I will present the results of two actual projects of mine, dealing with dust around stars and AGN. Based on observations with the Keck interferometer, we could show that the infrared-excess in transitional YSO class II disks typically derives from circumstellar disk material, and not from a close companion star. Disk dissipation induced by planet formation now appears to... Jörg-Uwe Pott |

Búsqueda de axiones mediante observaciones gamma de AGNs distantes Axion Like Particles (ALPs), postulated to solve the strong-CP problem in Particle Physics, may play a crucial role in the correct interpretation of gamma-ray astronomical observations as well as in the solution of the dark matter problem. They are predicted to couple with photons in the presence of magnetic fields, which may lead to a significant change in the observed spectra of gamma-ray sources such as AGNs. Indeed, this mechanism could... Miguel Ángel Sánchez-Conde (IAA-CSIC) Sala de Juntas del Instituto de Astrofísica de Andalucía (IAA-CSIC) |

Asteroids as the parent bodies of meteorites: compositional differences and size-dependent transport mechanisms Asteroids that come close to the Earth´s orbit (near-Earth asteroids, or NEAs) are targets of different sample-return space missions, providing us with material from their surfaces. Besides, we can also analyze the composition of meteorites in the laboratory, and run dynamical models that give us information about the source regions of NEAs and, consequently, the meteorites. By means of mineralogical analysis of their reflectance spectra,... Julia de León Cruz |

Comparing High and Low Redshift Quasar Properties: Black Hole Masses and Eddington Ratios Black hole mass and Eddington ratio estimates for quasars are of fundamental interest to astrophysicists and cosmologists. Comparisons of high and low redshift quasar properties are of special interest. Past comparisons have been unreliable because estimates are based upon measures of different emission lines in different redshift ranges. Are all broad emission lines valid virial estimators? Evidence suggests not motivating us to follow Hbeta... Jack Sulentic |
