Observaciones radiointerferométricas de discos de transición Los discos de transición son discos protoplanetarios con cavidades o huecos en sus zonas internas. Se han sugerido varios mecanismos para explica estas cavidades. El más aceptado y apoyado tanto por simulaciones como por observaciones es el del vaciado de material debido a la interacción gravitatoria del disco con un planeta recién formado. En esta charla explicaré cuáles son los rasgos observacionales característicos de los diferentes... Enrique Macías Sala de Juntas del Instituto de Astrofísica de Andalucía (IAA-CSIC) |

Astronomía y literatura ¿Tiene sentido esta mezcla? A tenor de las páginas que ya existen en la red, incluso parece que la idea está muy extendida. ¿Qué hace la Astronomía y qué hace la Literatura? En ambos casos, el científico y el escritor tratan de darnos su visión del mundo, son aproximaciones humanas a un entorno desconocido y a veces desconcertante. El primero trata de explicar, el segundo de conmover, pero ambos conmueven y explican. Emilio J. Alfaro y Susana Escudero |

Understanding the obscuring torus and the nuclear star formation of AGN using GTC/CanariCam observations The fueling of black holes occurring in active galactic nuclei (AGN) is fundamental to the evolution of galaxies. AGN themselves are largely explained in the context of a unified theory, by which a geometrically and optically thick torus of gas and dust obscures the AGN central engine. The torus intercepts a substantial amount of flux from the central engine and and reradiates it in the infrared. There are still many... Almudena Alonso-Herrero |

¿Por qué nos importan las formas de las galaxias? Las galaxias aparecen en el universo con formas distintas (unas son más esféricas, otras elípticas, espirales, o totalmente irregulares), y con una gran diversidad de estructuras (bulbos, discos, barras nucleares, brazos espirales, anillos, colas, etc). Estudiar estas propiedades morfológicas de las galaxias es justamente uno de los parámetros clave para entender cómo se forman y evolucionan. Mirjana Povic |

Activity and Evolution of Oort Cloud Comets Comets formed early in the evolution of the solar system while material was accreting to form planets. When proto-planets became large enough, a population of comets was dynamically ejected into the Oort cloud. Comets entering the inner solar system for the first time are called dynamically new comets. These objects have not been heated by the Sun and retain some of the most primordial material available for observation in the solar system... Dr. Dennis Bodewits |

Historia de un planeta canijo (o elogio de la soberbia)” La misión Solar Orbiter ocupa el lugar M1 del programa Cosmic Vision de la ESA. Se trata de una nave que orbitará el Sol con órbitas muy elípticas cuya mínima distancia al Sol será tan pequeña como la del radio medio de la órbita de Mercurio: tan solo un 30 % de la distancia entre la Tierra y el Sol. Dichas órbitas, además, se elevarán del plano de la eclíptica hasta 35º con lo que ofrecerán una visión inédita de los polos del Sol. Jose Carlos del Toro Iniesta |

Structural properties of isolated galaxies Distinct components of galaxies are products of internal and environmental processes throughout their lifetimes. Disentangling these processes is an important issue for understanding how galaxies form and evolve. In this context isolated galaxies represent a fruitful population to explore as they should be mainly affected by internal processes (minimal merger/accretion/tidal effects). I will present the structural analysis of a representative... Mirian Fernández Lorenzo |

First results from SDSS IV - MaNGA Large spectroscopic surveys of nearby galaxies (like the Sloan Digital Sky Survey) have shaped our understanding of galaxy evolution. However, to gain insight into the processes shaping the various galactic sub-components, a three-dimensional view (giving access to both spatial and spectral information) is necessary. In recent years, integral field spectroscopy (IFS) surveys of the nearby Universe (Sauron, CALIFA, Sami) are filling in this... Francesco Belfiore |

An ALMA view on the compact obscured nuclei of luminous IR galaxies Until recently, the study of the molecular interstellar medium of galaxies has been mostly focused on a few, relatively abundant, molecular species. Recent attempts at modeling the molecular emission of active galaxies have shown that standard high-density tracers do not provide univocal results and are not able to discriminate between different relevant environments (e.g., star-formation vs AGN). Spectral lines surveys allow us to explore... Francesco Costagliola |

La cuna de la vida: cómo se forman las estrellas y los planetas Hace casi veinte años que se descubrió el primer exoplaneta, pero desde mucho antes los astrónomos que estudiamos cómo se forman la estrellas ya teníamos evidencias de que otras estrellas como el Sol podían estar rodeadas de sistemas planetarios. Las estrellas se forman a partir del colapso de nubes enormes de gas y polvo. En este proceso, la estrella acaba rodeada de un disco en rotación a su alrededor. Mayra Osorio |

The non-thermal universe at the highest energies: TeV gamma-ray astronomy with the MAGIC telescope Some os the most violent processed in the universe present a non-thermal spectrum reaching energies of several tens of TeV. Due to the low fluxes at these energies, we need a technique capable to achieve collection areas of the order of the km^2. This can be reached by the Imaging Atmospheric Cherenkov technique and MAGIC is one of the main detectors for performing ground-based observations using this technique. It consists of two 17m...

The Fingerprint of a Galactic Nucleus: A Multi-Wavelength, High-Angular Resolution, Near Infrared Study of the Centre of the Milky Way The centre of the Milky Way is the only galactic nucleus and the most extreme astrophysical environment that we can examine on scales of milli-parsecs. It is therefore a crucial laboratory for studying galactic nuclei and their role in the context of galaxy evolution. Yet, suitable data that would allow us to examine the stellar component of the Galactic Centre exist for less than 1% of its projected area. This ERC-funded research programme... Dr. Rainer Schödel |

'What is the progenitor system of the nearby Type Ia SN 2014J?' Type Ia supernovae (SNe Ia) are the thermonuclear explosive end-products of white dwarfs. SNe Ia are primary cosmological distance indicators and a major contributor to the chemical evolution of galaxies, yet we do not know what makes a SN Ia. There are two basic families of models leading to a SN Ia, the single- degenerate model (SD) and the double-degenerate model (DD). In the SD scenario, a WD... Dr. Miguel Ängel Pérez Torres |

The brief lives of massive stars as witnessed by interferometry Massive stars present the newest and perhaps most challenging opportunity for long baseline interferometry to excel. Large distances require high angular resolution both to study the means of accreting enough mass in a short time and to split new-born multiples into their components for the determination of their fundamental parameters. Dust obscuration of young stellar objects require interferometry in the infrared, while post-... Dr. Christian Hummel |

Remote sensing: survival strategies in the jungle of averaging kernels and covariance matrices Outer space, stars, exoplanets, planets in the solar system, and even the Earth's middle and upper atmosphere have in common that it is inconvenient, expensive, and often technically unfeasible to make in situ measurements there. Remote sensing, e.g., by means of radiance measurements, is a relatively cheap and convenient alternative. The conversion of the measured radiances to the quantities of interest, e.g., temperature and composition... Dr. Thomas von Clarmann |

Inconsistences in the harmonic analysis of time series The power of asteroseismology relies on the ability to infer the stellar structure from the unambiguous frequency identification of the correspoinding pulsation mode. Hence, the use of a Fourier transform is in the basis of asteroseismic studies. Nevertheless, the difficulties with the interpretation of the frequencies found in many stars lead us to reconsider Fourier analysis and the classical methods used to process time series...
