A1689 is one of the most powerful gravitational lenses in the sky. In June 2002 we observed the center of A1689 with the ACS WFC for 20 orbits in the g,r,i,z bands, plus 3 orbits of grism observations. The resulting images are close to the depth of the HDFN over an area of 3.4'x3.4'.

The phenomenon of active galactic nuclei (AGN) has been one of the most intriguing subjects of astrophysical studies in the past several decades.

Actualmente hay un gran debate acerca de como ocurre la formación de una estrella masiva.

Circumstellar interaction of the shocked ejecta gives rise to emission in radio and X-ray bands.

La astrosismología es una de las herramientas más potentes que tenemos para el estudio de la estuctura interna de estrellas aisladas.

There is now general agreement that gamma-ray bursts involve extraordinary power outputs, posing a severe theoretical challenge and - irrespective of which detailed model proves correct - involving some fascinating and extreme physical processes.

La interacción de galaxias es un fenómeno común en el Universo.

The problem of ``stellar population synthesis'' is to derive the stellar population of an unresolved stellar system using a database of stars or clusters.

Dense molecular ISM is the site of star formation. FUV radiation from hot stars heat the nearby molecular gas establishing a region called Photon Dominated Regions (PDRs), where the physical and the chemical processes are dominated by the FUV field.

Aunque durante mucho tiempo no ha sido así, hoy se encuentra ampliamente aceptado el hecho de que los archivos juegan un papel fundamental en la investigación astronómica.

I will discuss results from the recently-completed H-alpha Galaxy Survey (HaGS), which resulted in H alpha and broad-band R imaging of 334 star-forming galaxies out to 3000 km/s, selected as an unbiassed subset of the Uppsala Galaxy Catalogue.

Results of an extensive H alpha survey of 8 low-redshift clusters to compare cluster and field galaxy star formation will be reviewed.

El globo estratosférico antártico SUNRISE es una colaboración entre Alemania, Estados Unidos y España y llevará a bordo un telescopio solar de nueva tecnología de C/Si C (el primario tiene 1 m de abertura y tan sólo 60 kg de peso).

Se revisan aspectos fundamentales de la Relatividad General y de sus aplicaciones, prestando un énfasis especial a los problemas cosmológicos actuales tanto teóricos como observacionales y, sobre todo, a la astrofísica de altas energías, en particular a aspectos presentes y futuros relativos a ag

It is proposed to explore the interaction of weak gravitational fields with slender elastic materials in order to assess the viability of achieving enhanced laser interferometric sensitivities for the detection of gravitational waves with frequencies between 1e-4 and 1 Hz.

As part of an outflow study in high-mass star-forming regions we observed the outflow in 20126+4104. It molecular outflow shows extremely high-velocity gas that extends in velocity more than +/- 50 km/s from the LSR.

Over the past 10 years, most of the galaxies in the Local Group have been observed by the HST for the purpose of studying their stellar populations. I will present a summary of some of these observations, and describe some of the key scientific questions that have been addressed with these data.
