The discovery of Gamma-Ray Bursts (GRBs), and the subsequent realization that they are the result of the largest and most distant explosions in the Universe, represents one of the most surprising and fundamental discoveries in astronomy in the past century.  Several space-borne and ground-based b

First direct detections of gravitational waves were reported in the first half of 2016.

A spectacular manifestation of solar activity, is the appearance of transient brightenings in the far wings of the H(alpha) line, originally known as "Hydrogen bombs” but now as "Ellerman bombs" (EBs) after their discoverer.

On June, 2013, a second edition of the Sunrise stratospheric, balloon-borne mission took place from Kiruna (Sweden) to Northern Canada. During these five days, the instruments aboard Sunrise were observing the Sun for long periods of stable conditions.

Low-mass galaxies are the most numerous type of extragalactic system at all epochs of the universe. The population of low-mass galaxies in the local volume allows unique astrophysical and cosmological perspectives that are unavailable in more distant or more massive systems.

La actividad científica e investigadora en el IAA, requiere el apoyo y soporte de gestión de las unidades de servicios administrativos. Estas se componen de los servicios económico-administrativos y los servicios generales (Biblioteca, Mantenimiento, Ordenanzas).

Modern astrophysics has revealed a Universe alive with explosions great and small. It is an astonishingly active place, far different from the serene “clockwork Universe” previously envisioned.

Blender es un potente programa multiplataforma que se distribuye libremente y es de código abierto. Entre sus aplicaciones más inmediatas está el modelado y la animación 3D, pero es un programa muy versátil que se puede usar para muchos otros propósitos.

One year after the final data release of the CALIFA survey, I will revise the results obtained from the analysis of the spatially resolved stellar population properties of galaxies and their impact on our knowledge on galaxy formation and their evolution.

Fractal and multi-fractal properties have been found both in fluid mechanics and geophysical related geometrical objects, as the convective boundary layer of cumulus cloud fields, ripple-wave turbulence, topographic and river networks patterns, solar granulation patterns, and in observational ast

The discrepancy between chemical abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major unresolved problem in nebular astrophysics, with significant implications for the determination of chemical abundances throughout the Universe.

The idea of detecting gravitational waves from space has been under consideration for more than 25 years. In 2012, the advisory bodies of ESA decided that the next-but-one "large mission", L3, will be devoted to this. Launch is scheduled for 2034.

Alone amongst the space agencies, ESA made its entry into space astrometry with the adoption of the Hipparcos mission in 1981. Outside of the astrometric community, it was viewed at the time as fundamental if not particularly exciting, although Freeman Dyson described it as "...

It is well known that there is little star formation activity in early-type galaxies. By cross-matching SDSS DR 7 with RC3 catalog and visually checking the SDSS images, we derive a sample of 583 S0 galaxies with the central spectrophotometric information.

Supermassive black holes, weighing between millions to billions times the mass of the Sun, are believed to power quasars and other energetic activity in the centers of galaxies.  With the help of advanced telescopes from the ground and in space, operating across the electromagnetic spectrum, astr

Future galaxy surveys of the large-scale structure in the Universe will provide a wealth of new data and make it possible to use higher-order statistics beyond the power spectrum, such as the bispectrum (or 3-point correlation function), to constrain galaxy clustering, the standard LCDM cosmology

The HI galaxy mass function represents a fundamental component of our understanding of the gas content of galaxies. How its form varies throughout the local Universe and as a function of redshift is key to developing a complete picture of galaxy evolution.

Esta charla pretende dar una visión general del estado actual del observatorio de Calar Alto mostrando los principales hitos conseguidos en los últimos años.

Metal-poor, star-forming, dwarf galaxies play a fundamental role in galaxy formation and evolution, and according to LambdaCDM models may be the building blocks of most of the galaxies in the universe today.
