It was noted soon after the discovery of the first quasars that some of them were surrounded by a nebulosity. Narrow-band imaging surveys and spectroscopic studies of quasars by Stockton et al. and Boroson et al.

En los últimos años se han lanzado dos misiones espaciales CoRoT (CNES, ESA) y Kepler (NASA) que presentan objetivos científicos. Por un lado, buscar exoplanetas, i.e.

This talk, which is intended for non-specialists and makes particular emphasis on astrophysical/cosmological implications, will review the underlying physical motivations for the suggestions that spacetime is noncommutative.

La Astronomía moderna no se puede concebir sin el trabajo realizado por todas aquellas mujeres que con su dedicación y amor a la ciencia nos han dejado su legado.

Attached to the 1.6-meter telescope of the Observatoire du Mont Mégantic in southern Québec, SpIOMM is an imaging Fourier transform spectrometer designed to obtain the visible range (350 – 850 nm) spectrum of every astronomical light source in a circular field of view of 12 arcminutes in diameter

The MAGIC-I telescope is currently the largest single-dish Imaging Atmospheric Cherenkov telescope in the world. A second telescope, MAGIC-II, will upgrade MAGIC-I in sensitivity, angular and spectral resolution from this year on.

The spiral galaxy M33 belongs to the local group and allows us to study star formation processes with great accuracy. The Spitzer telescope reaches spatial resolutions of the order of some parsecs and reveals the interactions between young stars and the interstellar medium.

En el camino hacia ALMA: técnicas de calibración de fase y gas molecular en grupos compactos de galaxias

We present a self-consistent MHD model for the jet of M87. The model consist of two distinct zones: an inner relativistic outflow and an outer cold disk-wind.

We present a new time-dependent inhomogeneous jet model of non-thermal blazar emission, which reproduces the entire spectral energy distribution together with the rapid gamma-ray variability. Ultra-relativistic leptons are injected at the base of a jet and propagate along the jet structure.

Nuestro grupo ha utilizado 130 órbitas del HST/ACS para obtener diagramas color-magnitud profundos de 65 cúmulos globulares de la Vía Láctea ("Treasury Project on Galactic Globular Clusters").

To understand the evolution and appearance of galaxies it is crucial to study the interplay between stars and the interstellar gas and dust. I will present results and plans to study the ISM and star formation in the nearby galaxies M51 and M33.

Las apariencias engañan. El 10 de junio de 2007 el satélite SWIFT descubrió lo que aparentemente era otro estallido de rayos gamma en la dirección de la Via Láctea.

Cosmic reionization - the process of ionization of the bulk of cosmic gas by ultra-violet radiation from primeval galaxies - is by far the most dramatic event that occurred in the universe since the formation of the first star.

I present a study aimed at determining the effective temperature and surface gravity of a sample of nine T-type field T dwarfs from the comparison of high-resolution near-infrared spectra and synthetic models.

Aunque es bien conocido que la historia evolutiva de las galaxias está fuertemente condicionada por el entorno, la evidencia observacional no es siempre suficientemente clara o concluyente.
