A menudo se usa un criterio conocido como "masa virial" para estimar la masa de un halo de materia oscura.

Se mostrarán resultados de la evolución de propiedades de las galaxias, como formación estelar, atenuación y masa estelar para una muestra de galaxias del Chandra Deep Field South seleccionadas en UV (~2315 A) en un rango de redshift intermedio (0.2 < z < 0.7).

La asterosismología nos permite conocer el interior de las estrellas a partir del estudio de sus oscilaciones.

The World Space Observatory UltraViolet (WSO-UV) project is an international space observatory designed for observations in the ultraviolet domain where some of the most important astrophysical processes can be efficiently studied with unprecedented capability.

High redshift radio galaxies are thought to be beacons to massive elliptical galaxies in the early universe.

To fully understand how molecular clouds survive long enough to sustain multiple star forming epochs it is essential to know in detail their star forming histories.

Se presentará una visión general de los nuevos conocimientos en los cuerpos menores del Sistema Solar como meteoritos, asteroides y objetos trans-neptunianos.

Se estudió la emisión máser proveniente de un anillo gaseoso, delgado y plano, en rotación kepleriana alrededor de un objeto central masivo y visto de canto.

Un "Sistema de Control de Versiones" (SCV) es una herramienta que permite gestionar las diferentes revisiones de un documento a lo largo de su ciclo de vida.

Research in Astronomy is sometimes compared with the activity of a detective, trying to solve a crime scene. This is the case we were faced with when we discovered an enigmatic astronomical source. The discovery took place during our effort to put together a catalog of IRAS-based protostars.

Nature is one of the world's leading scientific journals, publishing many papers that receive wide attention by the general public. But, Nature is very selective-- <7% of submitted papers are published.

In this talk I will review the constraints on the Active Galactic Nuclei (AGN) structure model emerging from X-ray studies of nearby Seyfert galaxies.

We present the first results of a program of observations of a sample of distant galaxies ($z_{median}=0.8$) at high spatial resolution ($ \sim 0.1"$) aiming at studying their morphological evolution with redshift.

Scattered light echoes offer one of the most effective means to probe the structure and composition of circumtellar and interstellar media. Of note, light echoes provide exact three-dimensional positions of scattering dust.

The core emission of the Ca II H and K lines are one of the important sources of the radiative loss in the solar chromosphere. The H-index is the integrated emission in a 0.1 nm band around the Ca II H line core.

Evolved descendants of Main Sequence O-types stars, B- and A-type supergiant stars are among the most luminous "regular" objects in galaxies with recent star formation.

El proyecto AMIGA tiene como objetivo proporcionar y estudiar una muestra bien definida de las galaxias más aisladas. Esta muestra puede sirvir de base para el estudio del papel del entorno en la evolución de galaxias.

The role of the environment on galaxy evolution is still not fully understood. In order to quantify and set limits on the role of nurture one must identify and study a sample of isolated galaxies.

Accretion of matter onto a super massive black hole (SMBH) is believed to be the dominant mechanism for the emission production in Active Galactic Nuclei (AGN).

Las explosiones cósmicas de rayos gamma (GRBs) son fogonazos breves pero intensos de altas energías que durante unos segundos se convierten en las fuentes más brillantes del Universo en gamma.

Se describe el proyecto coordinado por el CSIC de una infraestructura grid europea orientada a soportar trabajos interactivos con necesidades de cálculo importantes, a través de paralelización.
