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,... Dr. Luca Izzo |

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... Dr. Jose Francisco Gómez |

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... Dr. Lorena Hernández García |

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. Mary Loli Martínez Aldama |

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. Prof. Nicholas Macdonald |

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.

Mientras que la evolución estelar conforma un cuerpo teórico bien estructurado, incluyendo aquí las últimas fases de la misma, la formación estelar está lejos de admitir una formulación teórica predictiva que permita, conociendo las propiedades físicas de la nube molecular, pergeñar las propiedades de la futura población estelar naciente.

The lifetime dilemma of evaporating black holes The standard view is that black holes exist, maybe not with all the properties of strict black holes in classical General Relativity, but sufficiently close to them that one does not need worrying in the astrophysical practice. Dr. Carlos Barceló |
