The study of the molecular gas in quasars and submillimeter galaxies at high redshift has significantly progressed during the last few years.

Cometary dust environment modeling is an essential tool for the planning of the future operations and the data evaluation of Rosetta and other missions towards comets.

The continuum radiative transfer is a common problem in astrophysics that must be solved to describe the physics and interpret observations of objects embedded for instance in a dusty medium.

En los últimos años hemos recopilado datos de un conjunto de nebulosas planetarias (NP) cuyas propiedades indican que se encuentran en un estado evolutivo avanzado.

La antena de 70m de la estación espacial de NASA en Robledo de Chavela se utiliza regularmente para realizar observaciones de líneas moleculares en 1cm. En este rango, es uno de los radiotelescopios más sensibles del mundo.

Over the past four years, a collaboration of data centers and universities in the United States has been working in conjunction with international partners worldwide to build the framework for the Virtual Observatory.

La teoría cosmológica de la Materia Oscura Fría ("Cold Dark Matter") predice que las galaxias similares a la Vía Láctea se formaron a partir de la destrucción por marea y posterior aglutinamiento de un gran número de fragmentos de baja masa parecidos a las galaxias enanas que observamos en el pre

I. Nuevas tecnologías disponible en IDL para soluciones potentes e integradas:

La distribución de separaciones de las componentes de estrellas dobles y múltiples contiene importante información sobre las condiciones existentes durante la formación estelar y la posterior evolución dinámica de los parámetros orbitales.

The Sloan Digital Sky Survey (SDSS) will map one-quarter of the entire sky and perform a redshift survey of galaxies, quasars and stars. The SDSS Catalog Archive Server (CAS) offers efficient search tools for querying the imaging and spectra catalogs.

We have used the Advanced Camera for Surveys (ACS) on the HST to obtain optical imaging of a sample of 7 galaxy clusters in the redshift range 0.8<z<1.3.

We present results and progress notes from an investigation into the rotation curves of spiral galaxies at high and low redshift. We discuss work done with data from the DEEP2 (Deep Extragalacitc Evolutionary Probe) spectroscopic survey, which is a major effort to characterize galaxies at z~1.

Asteroid families are the remnants of catastrophic collisions between asteroids and, so, we should expect a sort of mineralogical coherence among its members.

The evolution of a galaxy and its nuclear black hole is now widely thought to be co-eval.

La fracción de galaxias barradas ha crecido enormemente en las últimas décadas. Actualmente, las estructuras barradas (barras u óvalos) no deben tratarse como una rareza o una pecularidad que exhiben algunas galaxias.

En esta charla se dará un informe del congreso "Communicating Astronomy with the Public", organizado por ESA, ESO e IAU en Munich, que tocará entre otros los siguientes puntos:

In recent years there has been a growing interest in the study of space-times embedded in some higher-dimensional space (see e.g. brane models, induced matter theory, ...).

Optical afterglows of GRBs provide vital information about the nature of the progenitors and the energetics. Observed achromatic steepening in several optical afterglow light-curves show evidence for the presence of the jet-break, constraining the total output energy.

Previews of both parts of this DVD can be seen at www.universe-film.com. It can be thought of as the "inelegant universe" response to the recently shown "Elegant Universe" film that glorifies the standard model.

The study of the stellar content of distant galaxies has a long and venerable history but, at the same time, something of a 'bad reputation' due to the numerous problems associated with dificulties in disentagling age, metallicity and extinction effects.

I will briefly review my research interest on Low Surface Brightness Galaxies (LSBGs). I will show the latest results from our survey for LSBGs with the Sloan Digital Sky Survey (SDSS) data.

Enrique, Valentina y Miguel Ángel nos presentarán un resumen (¡prometen que no será de más de 25 minutos!) de COMCIENCIA05, un curso de formación para científicios al que asistieron del 11 al 3 de Mayo, en Barcelona.

The quasar spectral energy distribution (SED) in the UV is characterized by a sharp break near 1000 A. The SED (in Fnu) of quasars can be described by a broken powerlaw. Telfer et al.

The solar coronal heating is one of the most important problem to be solved for the astrophysics. Although it is widely accepted that the magnetic filed emerging from the solar surface plays an essential role for the coronal heating, the detailed mechanism is totally unknown.
