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.

Nuclear star clusters (NSCs) are present at the photometric and dynamical centers of the vast majority of galaxies. They are the densest known clusters in the Universe. Unfortunately, extragalactic NSCs can be barely resolved, even by the HST or ground based adaptive optics observations.

Discovery of relation between long-duration gamma-ray bursts (GRBs) and supernovae (SNe) is the most important progress in this domain during recent 10 years.

Since its launch in September 2006, Japan-US-UK solar physics satellite, the Hinode, has continued its observation of the sun, sending back solar images of unprecedented clarity every day.

Se presentará el estado actual en que se encuentra PANIC (PAnoramic Near Infrared camera for Calar Alto), la nueva cámara infrarroja de gran campo para el telescopio de 2.2 m de CAHA.

Se repasarán las tendencias y correlaciones entre los espectros de tipo O normales en los rangos visible, ultravioleta y rayos X.
