We have carried out a concept study for a wide-field monolithic integral field unit (IFU) spectrograph for extremely large telescopes (ELTs). We target in this paper the technological challenges that have to be faced in order to build such an instrument, focusing on the adaptive optics (AO) requirements, the image slicer technology, and the

Asteroid 944 Hidalgo is suspected of being an extinct comet. Understanding the origin of this enigmatic object is relevant to several areas of planetary astronomy, and the study of its surface composition may be diagnostic of its origin. Silicates have been detected in active comets, and on Jupiter Trojans. Our team investigated Hidalgo in the 8-30

Recent high-resolution observations have pointed out that prominences are made of small threads (also named fibrils) piled up to form the body of the prominence. These fine structures also seem to support their own oscillatory modes, while their effect on the global modes of the prominences are less certain. We study the effect of adding a smooth

The Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescope was designed for the detection of photon sources >~50 GeV. The measurement of highly-inclined air showers renders possible the search for high-energy neutrinos, too. Only neutrinos can traverse the Earth without interaction, and therefore, events close to the horizon can be identified

The majority of bright gamma-ray transients that we observe in the sky, are produced by extragalactic gamma-ray bursts (GRBs). However, we know that there are other kinds of sources that can produce intense bursts of high-energy photons within our own Galaxy. GRB 070610/Swift J195509+261406, being just 1 degree away from the Galactic plane, is one

Estudio estadístico de poblaciones de cúmulos en galaxias interactuantes. Correlación de propiedades de dichos cúmulos junto con las características de la galaxia anfitrión. Implicaciones en la evolución de galaxias a través de la nueva población de cúmulos creada en la interacción.
