In the framework of the GLACE project, we present the preliminary results of a mapping of emission lines (Hα+[NII], Hβ and [OIII]) in the rich cluster Cl0024+1654 at z=0.4, using the red tunable filter of OSIRIS/GTC. This emission-line survey has been designed to detect emission-line galaxies (ELGs) whose fluxes correspond to SFR up to 2 M_&sun;/yr

We performed a uniform and detailed analysis of 1112 high-resolution spectra of FGK dwarfs obtained with the HARPS spectrograph at the ESO 3.6 m telescope (La Silla, Chile). Most stars have effective temperatures 4700 K ≤ Teff ≤ 6300 K and lie in the metallicity range of -1.39 ≤ [Fe/H] ≤ 0.55. Our main goal is to investigate whether there are any

Here we give a brief outline of the activities developed during the International Year of Astronomy specifically addressed to people with various disabilities, both physical and/or intellectual. Among the different activities that we carried out we wish to highlight the publication of an astronomy book in Braille, astronomy talks for the

We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel, the merging of two low-mass stars. We show that the abundance and properties of W UMa stars and low mass detached binaries are consistent with their being possible progenitors. The degree of inflation of the transiting hot Jupiters correlates with

Tenerife is not Jakarta. Neither is 2009 the year 1965, nor the Museo de la Ciencia y el Cosmos (Museum of Science and the Cosmos) the hotel "Indonesia", meeting point of reporters from around the world. Nor am I the journalist Jill Bryant (Sigourney Weaver) in the Australian Peter Weir film. But 2009, a year of international commitment to
