Al comparar magnitudes observadas y sintéticas de longitudes de onda y sistemas de filtros distintos, es frecuente encontrarse con errores sistemáticos debidos a la calibración.

I present new results on the young stellar populations in powerful radio galaxies based both on optical spectroscopy and far-IR/sub-mm photometry (including recent Spitzer data).

GRB 050319 (z = 3.24) and GRB 050401 (z = 2.9) are long duration and distant GRBs. Their afterglows show unusual and interesting features. We have modeled these afterglows using Fireball Model. We show that GRB 050401 afterglow provides another case for 'Double Jet' at a redshift of 2.9.

Se pueden observar los cúmulos globulares de las galaxias cercanas y usarlos como pruebas dinámicas a grandes distancias de su galaxia anfitriona. Voy a presentar un estudio de los sistemas de cúmulos globulares en los alrededores de galaxias situadas en varios entornos.

Los modelos de síntesis tradicionales tratan las propiedades integradas de las poblaciones estelares de forma determinista.

Multiwavelenghts studies of massive star formation regions in the LMC and SMC reveal that a second generation of stars is being formed in dense molecular clouds located in the surroundings of the massive clusters.

I will present some recent results from two Integral Field Spectrographs (SAURON and GMOS-IFU) together with high resolution images from the Hubble Space Telescope, providing a unique data set for studying dynamics of galaxies.

Active star formation is tightly related to the dense molecular gas in the giant molecular cloud dense cores.

El instrumento MIPAS a bordo del satélite europeo Envisat lleva 4 años midiendo emisiones infrarrojas (4 - 15 um) de la atmósfera terrestre con elevada resolución espectral y espacial.

I review theoretical arguments which suggest only high mass stars can form from primordial gas. But low-mass extremely metal poor stars do exist and so the question of whether they formed from primordial gas, and later accreted their metals from the interstellar medium, does arise.

Se celebra este año el 25 aniversario de la creación del Observatorio de Sierra Nevada (OSN).

La práctica de la investigación científica en Astrofísica a comienzos del siglo XXI ha visto incrementado significativamente el volumen de datos a su disposición gracias a las exploraciones sistemáticas del cielo por observatorios robóticos o a los altos ciclos útiles de las misiones espaciales.

It is well-established that clusters are dominated by red galaxies wirh old stellar populations, while the field population consists mostly of blue galaxies with younger stars. The origin of this relation may be due to 'nature' or 'nurture'.

Dwarf galaxies are the most common galaxies in the Universe. They are systems believed to consist of matter in a near-primordial state, from which giant galaxies probably form. As such, they are important probes for studying matter in its near-primordial state.

It has been known for a long time, that the cosmic SFR has declined by 3-10 fold since redshift ~1. Since major mergers are effective triggers of star formation and have been more common in the past, it has been argued that the decline is driven by the merger evolution.

We employ high-resolution N-body simulations to model luminosity-dependent clustering from z=5 to z=0.

Uno de los retos científicos más fascinantes a los que nos enfrentamos hoy en día es descubrir cuál es la naturaleza de lo que conocemos como Materia Oscura.

Se presentaran los resultados que hemos obtenido recientemente sobre las propiedades de las galaxias dentro de los grandes vacios en la estructura a gran escala encontrados en el Sloan Digital Sky Survey.

I use a detailed self-consistent model of galaxy formation and the Millennium Run LCDM N-body simulation to explore the evolution of the galaxy population, including super-massive black hole growth, in a cosmological context.

Observational evidence suggests that Radio Galaxies are hosted by massive elliptical galaxies (M_sun=10**[11.5-12]) at every redshift. Using Spitzer we can for the first time measure the peak of the stellar luminosity at rest-frame NIR.

Los scripts son una poderosa herramienta de programación aplicable a las fases de validación y producción de Software.

The Hubble Ultra Deep Field (UDF) provides us with our deepest view to date of the visible universe. The UDF ACS images cover twice the area of the previous Hubble Deep Fields and are about 1 magnitude deeper.
