A 2D Spectroscopy view of NGC 588 Most of today's stars were formed in high intensity episodes about 7-10 Gyr ago. However, at these redshifts both resolution and dimming effects make it difficult to study in detail the interaction of the gas, dust and newly formed stars. Giant H II regions in very nearby galaxies constitute their best local counterpart to address such a study. Here, I present an analysis of NGC 588, a GHIIR in M33, based on optical Integral Field Spectroscopy... Ana Monreal Ibero |

Gravitational Wave Astronomy in the 21st Century The discovery of the binary pulsar PSR B1913+16 by Hulse and Taylor provided definite evidence of the existence of gravitational waves as predicted by Einstein's General Theory of Relativity. It also contributed to encourage the development of different gravitational wave detectors that was pioneered in the 60s by Joseph Weber. Presently, we have a world-wide network of ground detectors that is expected to achieve the first detections during the... Carlos F. Sopuerta |

The Physics and Philosophy behind Cosmic Time How far back in time can we have knowledge of the universe? Most cosmologists would agree that the physics describing the ‘material content’ of the universe becomes increasingly speculative the further we go back in time. By contrast, it is widely assumed that the concept of time itself – by virtue of the cosmological standard model – can be safely extrapolated sixty orders of magnitude back from the present to the Planck...

A Magnetized Jet from a Massive Protostar Supersonic jets are observed to emerge from a wide variety of astrophysical systems, from young stellar objects (YSOs) to AGNs. Despite their different physical scales (from hundreds to billions of astronomical units), they have strong morphological similarities. However, it is yet unclear whether there is a universal mechanism that can explain the origin of all these jets. Theoretical models suggest that the magnetic field is a fundamental...

The Transneptunian Region and Clues about Planet Formation The Transneptunian belt is a reservoir of icy bodies in the outer reaches of our solar system. This region is believed to be the source of the Jupiter-Family Comets and is also thought to contain very pristine material, the leftovers of planet formation beyond the ice line. Therefore, the TransNeptunian Objects (TNOs) carry important information on how the solar system was formed, and can give plenty of details on the processes that were... José Luis Ortíz |

CheFlet polar basis for astronomical data analysis We present a new method to decompose galaxy images. We have developed a polar orthonormal basis, built using Chebyshev rational functions to expand the radial coordinate, and Fourier series to represent the azimuthal component. The method can fit galaxies in a very compact way, including simultaneously most of the galaxy substructure and the extended wings of the galaxy profile. Some applications of this method are being developed: photometry... Yolanda Jiménez Teja - Sala de Juntas del Instituto de Astrofísica de Andalucía (IAA-CSIC) |

Star formation at small galactic scales We present a study of the distribution of star, gas, and dust components in star-forming regions in nearby galaxies. The targets sample a wide range of luminosities and morphologies in order to study how the violent star formation influences the dust and gas distribution inside the star-forming regions. The analysis is based on the comparison of multi-wavelength data from theFar-Ultraviolet (GALEX) to the Infrared (SPITZER and HERSCHEL). Mónica Relaño |

Sondeo de la alta atmósfera de Venus y Marte usando espectroscopía molecular en el IR La alta atmósfera de los planetas terrestres se caracteriza, entre otros aspectos, por sus bajas densidades y condiciones ópticamente delgadas a la radiación solar en el visible/UV. La única excepción son las bandas moleculares IR en la región espectral por encima de 2um por las cuales los procesos radiativos se hacen significativos. Por tanto, las observaciones IR constituyen una herramienta ú... Gabriella Gilli - Sala de Juntas del Instituto de Astrofísica de Andalucía (IAA-CSIC) |

El campo magnético en galaxias El campo magnético de una galaxia no es solamente importante porque nos proporciona un método de observación, sino también por sus efectos dinámicos. En el pasado se estudió el proceso v -> B pero cada vez se reconoce más el proceso B -> v , es decir el campo magnético ha dejado de ser una magnitud pasiva para influir activamente en el movimiento. La importancia del magnetismo galáctico afecta a determinadas estructuras y también... Eduardo Battaner |

Dark matter on department scale The direct detection of dark matter on Earth depends on its density and its velocity in the Solar neighbourhood. Unforunately, it is uncertain whether the dark matter distribution on the relevant physical scales (milliparsec) is homogeneous or not. Traditional N-body simulations cannot achieve the required resolution, so we have developed an ingenious method, able to achieve virtually any arbitrary resolution at almost no computational cost....

A new sample of faint blazars The available blazar samples were selected at relatively high limiting flux densities in the radio and X-ray band. Those samples have small sizes (30-50 objects) making it difficult to statistically derive parameters related to beaming effects. Moreover, the estimate of those parameters is based on bright and intrinsically luminous sources. A deeper, larger sample of blazars has been constructed by Perlman et al. (1998) and by Landt et al. (2001... Franco Mantovani |

Mesospheric CO2 clouds on Mars: observations and study with a General Circulation Model Mesospheric CO2 clouds have been recently observed on Mars, providing important information about the temperatures and winds at the mesosphere, an atmospheric region characterized by the scarcity of observational records. These clouds only appear at particular geographical locations, altitudes above the surface, and times of the year, posing interesting questions about the processes that are at the origin of these clouds. We use a computational... Francisco González Galindo |

On the discovery of the Zeeman effect on the Sun and in the laboratory The origin of the discoveries, both on the Sun and in the laboratory, of the action of a magnetic field on spectral lines, the so-called Zeeman effect, is discussed. The talk embraces the period from 1866, the first date of which the speaker is aware of observed evidences about the widening of spectral lines in sunspots (as compared to those formed in the photosphere), until 1908, the year in which the magnetic field in sunspots is definitely...

Umbral dots: clues to the internal structure of sunspots Sunspots have been studied since the time of Galileo, but they still remain one of the most active research fields in solar physics. Especially, research on the fine structure of sunspots made great progress with the advent of the Hinode satellite and CRISP spectropolarimetry at the Swedish Solar Telescope on La Palma. Umbral dots (UDs) are tiny bright points observed in the umbra of sunspots. They are scientifically interesting because they... Hiroko Watanabe |

Active Galactic Nuclei at parsec scales We present a representative SED for low-luminosity AGNs, built from high-spatial resolution data for the LINERs and faint Seyferts in the sample. This distribution differs from those of bright Seyferts and Quasars, suggesting that the internal structure of AGNs appears to be largely determined by the amount of energy released by the central engine. On the other hand, we present a multiwavelength study of the nuclear star-formation (~2.5kpc x 2.... Juan Antonio Fernández Ontiveros |

Fundamental Constants in Time and Space According to the standard model of particle physics, fundamental constants, at least their low-energy limits, should be independent of time and location. Many fundamental constants of physics and astronomy are well defined locally. However, this "constancy of constants'' may not necessarily hold over the largest spatial and temporal scales, which are inaccessible by geological or astronomical studies of nearby targets. Now, advances in... Christian Henkel |

An Initial Mass Function for Individual Stars in Galactic Disks The Initial Mass Function (IMF) has been derived by a variety of methods. Here we propose an IMF form (a Smoothed Two-Power Law psi_STPL) that approaches a power law at both low stellar masses (psi_STPL ~ m^(gamma)) and at high stellar masses (psi_STPL ~ m^(-Gamma)) with a turnover near the characteristic mass m_ch. The values of gamma and m_ch are derived from two integral constraints: i) the ratio of the number density of stars in the range m=... Antonio Parravano |

Magnetic field configuration at the central region of our Galaxy It has been long debated whether the magnetic field configuration at the central region of our Galaxy is toroidal or poloidal. Previous works that have addressed this question were mainly based on radio observations of non-thermal radio filaments, and sub-mm polarimetric observations of dense molecular clouds. I will present a result of a wide-field near-infrared polarimetric survey of the central 2 deg by 2deg region; these wavelengths trace... Shogo Nishiyama |

Unfolding Properties of Mass Loss at the Tip of the Asymptotic Giant Branch In the final stages of stellar evolution low- to intermediate-mass stars lose their envelope in increasingly massive stellar winds. Matter, which has been processed inside these stars, is thereby returned to the interstellar medium, and mass loss also determines properties of subsequent planetary nebulae. In order to obtain properties of winds at the tip of the asymptotic giant branch we observed weak halos of a set of planetary nebulae in the... Christer Sandin |

Observational constrains to galaxy evolution from the distribution of integrated stellar ages and metallicities in spiral galaxies I will present new results on the integrated stellar populations of bulges, bars and disks of spiral galaxies from long-slit spectroscopic observations. We have derived the ages and metallicities using both the whole spectra and stellar line-strength indices along the bar and bulges for a sample of 20 disk galaxies and derived the populations in the disks of four galaxies using GEMINI spectroscopic data. We find, in the distribution of stellar... Isabel Pérez Martín |

The First 3mm Polarimetric Survey of Radio Loud AGN Relativistic jets in AGN are the most energetic and among the most powerful astrophysical objects known so far. Their relativistic nature provides them the ability to emit profusely in all spectral ranges from radio wavelengths to TeV gamma-rays, as well as abrupt variability in all time scales (from hours to years). After an extended review of the present knowledge of these objects, but paying particular attention to blazars, the main results... Iván Agudo Rodríguez |

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 |

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) |

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 |
