The physics of the formation of first stars will be reviewed. The first stars formed in the first dark matter halos where gas was able to cool through molecular hydrogen lines.

En esta charla se presentan herramientas que ya están accesibles dentro del marco del Observatorio Virtual (VO) para realizar análisis de datos.

One of the most interesting features discovered by Chandra satellite observations of galaxy clusters are the sharp X-ray surface brightness discontinuities, accompanied by jumps in gas temperature named “cold fronts”.

Se presenta una revisión del principio de invariancia gauge para simetrías internas y su generalización al caso espacio-temporal.

Current mm-interferometers can provide a complete view of the distribution and kinematics of molecular gas in the circumnuclear disks of nearby galaxies.

El estudio de las galaxias anfitrionas de brotes de rayos gamma se ha convertido en una pieza clave para entender estos objetos.

Transient Luminous Discharges (TLD) are large scale optical events taking place at stratospheric and mesospheric/lower ionospheric altitudes (40 – 90 Km), which are directly connected to the electrical activity in underlying thunderstorms.

I will discuss our analysis of Spitzer data in combination with other multi-wavelength observations to improve our understanding of galaxy formation and evolution in the last 12 Gyr.

I will present the concept status of the first ideas proposed for the construction of a wide-field MOS and IFU fiber-fed intermediate resoltution common user optical and near-IR spectrograph for the GTC.

Presentación de las actividades del IAA en la semana de la ciencia 2006.

All the effort that the astrophysical community has put into the development of the Virtual Observatory (VO) has surpassed the non-return point: the VO is a reality today, and an initiative that will self-sustain, and to which all archival projects must adhere.

En los últimos años se han acumulado suficientes indicios que vinculan la evolución de los objetos compactos supermasivos motores de los AGN, y la formación del bulbo de la galaxia anfitriona.

En esta charla de orientación práctica describiré cómo funciona CHORIZOS, un código bayesiano escrito en IDL que permite ajustar modelos de distribuciones espectrales de energía arbitrarios (estrellas, cúmulos, galaxias...) a observaciones fotométricas (o espectrofotométricas) arbitrarias para pr

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.

El doctorado en el IAA

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.
