Space astrometry: the Hipparcos and Gaia missions
The talk will provide a short historical context and describe the scientific motivation for these missions, outline the essential experimental principles which underpin their measurements, and give an overview of the science objectives, including Gaia's expected yield of many thousands of astrometrically-detected exoplanets.

Star formation in nearby early-type galaxies
It is well known that there is little star formation activity in early-type galaxies. By cross-matching SDSS DR 7 with RC3 catalog and visually checking the SDSS images, we derive a sample of 583 S0 galaxies with the central spectrophotometric information. In order to separate nebular emission lines from the underlying stellar contribution, we fit the stellar population model to the SDSS spectra of these S0 galaxies. According to the BPT diagram...

Supermassive Black Holes: Impact on Galaxy Formation and Evolution
Supermassive black holes, weighing between millions to billions times the mass of the Sun, are believed to power quasars and other energetic activity in the centers of galaxies. With the help of advanced telescopes from the ground and in space, operating across the electromagnetic spectrum, astronomers have now discovered that supermassive black holes not only exist, but that they are very common and play a critical role in the formation and...

Recovering information beyond the power spectrum of large-scale structure
Future galaxy surveys of the large-scale structure in the Universe will provide a wealth of new data and make it possible to use higher-order statistics beyond the power spectrum, such as the bispectrum (or 3-point correlation function), to constrain galaxy clustering, the standard LCDM cosmology, and many of its possible extensions. However, it may be possible and preferable to use recently devised alternative statistics, such as the line...

The impact of environment and confusion of the observed HI galaxy population
The HI galaxy mass function represents a fundamental component of our understanding of the gas content of galaxies. How its form varies throughout the local Universe and as a function of redshift is key to developing a complete picture of galaxy evolution. We use the ALFALFA 70% catalogue, the largest uniform catalogue of extragalactic HI sources to date, to explore the environmental dependence of the HI mass function based on the projected...

Molecular gas and dust in low-metallicity starbursts
Metal-poor, star-forming, dwarf galaxies play a fundamental role in galaxy formation and evolution, and according to LambdaCDM models may be the building blocks of most of the galaxies in the universe today. Although the interstellar medium (ISM) in such galaxies was thought to be virtually dust-free, over the last decade, observations have shown that dust can be an important constituent of even a low-metallicity ISM. However, the molecular...

Cold plasma and magnetic reconnection at the magnetopause boundary layer
Magnetic reconnection is a fundamental plasma process that permits the exchange of energy and mass between colliding plasmas, e.g., between the Solar Wind and the Earth's magnetosphere. Several studies have reported the presence of cold plasma of ionospheric origin at the magnetospheric side of the magnetopause boundary layer. As a result, the particle distribution functions involved in reconnection are far from equilibrium, exhibiting a cold...

Living on the Edge: Superthin Galaxies and the Cosmic UV Background
Superthin galaxies are bulgeless, late-type spiral galaxies seen edge-on. HI synthesis observations probe the kinematic structure of their interstellar medium. Observations of these isolated, quiescent galaxies have reached column densities as low as few x 1018 atoms . cm-2 . The simple structure of the superthins makes them ideal cosmological laboratories (Uson and Matthews, Astron. J. 125, 2455, 2003). I shall present the results of high-...

Azar y complejidad (coloquio en el marco del festival Cinemística)
Parece que el azar juega un papel  esencial a la hora de que en un sistema se generen estructuras complejas. ¿Qué se entiende por sistemas complejos?, ¿hay un aumento de complejidad en la naturaleza con el tiempo?, ¿puede un sistema determinista generar complejidad?

Asteroid surfaces: irradiation and VIS-IR micro-spectroscopy in the laboratory
Primitive extraterrestrial materials, such as meteorites and dust collected by sample return missions, are characterized by a large compositional heterogeneity at different scales. This heterogeneity has been observed in the laboratory by different techniques. Among these, micro-IR spectroscopy has the advantage of being totally non-destructive and allowing direct comparison with astronomical observations. With the development of Focal Plan...

Novae as Lithium factories in the Milky Way
The abundance of Lithium observed in very young stellar populations is ~4 times larger than the primordial one estimated by recent Planck measurements. Since Lithium is easily destroyed in stellar interiors, the search for astrophysical sources responsible for of the observed Lithium over-abundance was a mystery for decades. In this seminar I'll discuss the recent detection of Lithium in the spectra of two slow novae, V1369 Cen and V5668 Sgr,...

Witnessing the birth of a planetary nebula
Planetary nebulae are one of the last stages of evolution of stars like our Sun. The beginning of photoionization, giving rise to a new planetary nebula, will certainly produce dramatic changes in the object, but this instant is difficult to observe, since it will only take a few decades. During of a long-time study of water masers in post-AGB stars and planetary nebulae, we identified an object (IRAS 15103-5754) in which we believe...

Multiwavelength analysis of PBC J2333.9-2343
Nuclear activity as is observed in active galactic nuclei (AGN) might be a phase occurring in all galaxies, and this activity could be recurrent. A perfect laboratory to test these scenarios are the giant radio galaxies, since their emission can be as old as 10⁷-10⁸ years. In the present work we focus on the nucleus of PBC J2333.9-2343, which called our attention because it is a giant radio galaxy that shows different and incompatible...

The CaII triplet in Quasars: from the accretion disk to the star formation
Active galactic nuclei (AGN) show a great diversity of optical and UV emission line properties. Dynamical and physical models should be built accordingly. The presence of strong FeII emission suggested the existence of a region shielded from high energy photons, where the low ionization lines are emitted.

Blazars: Order and Disorder
Blazars are the most luminous persistent objects in the sky. They emit light across the entire electromagnetic spectrum, from low-energy radio waves to high-energy gamma-rays, and they exhibit variability on timescales that range from years down to minutes. The launch of the Fermi Large Area Telescope (LAT) in 2008 has ushered in a new era of high-energy astrophysics.

The magnetic field vector in solar chromospheric structures: the diagnostic potential of the near infrared He I 1083nm triplet
The solar chromosphere is permeated by solar structures such as sunspots, surges, flare ribbons, prominences (filaments) or spicules, where non-local thermodynamic equilibrium effects dominate the state of the plasma and where the magnetic fields are expected to be much lower in intensity than in the photosphere underneath.
