We present the study of the most massive galaxies (M^{*}>10^{11} {M}_{&sun;}) found in a cosmological simulation performed with MASCLET (Mesh Adaptative Scheme for CosmologicaL structurE evoluTion) and analyzed with HALMA (HALo finder for MAsclet). We focus on the structure of these virtual galaxies, analysizing their radial gradients, morphology

We will review theoretical, experimental and observational work on the new form of carbon known as fullerenes and its hydrogenated forms (fulleranes). This type of molecules can be responsible for diffuse interstellar bands, for the UV ``bump", a remarkable feature of the extinction curve observed in many lines of sight of our Galaxy and other

FRIDA (inFRrared Imager and Dissector for the Adaptive optics system of the Gran Telescopio Canarias) is being designed as a diffraction limited instrument with broad and narrow band imaging and integral field spectroscopy capabilities to operate in the wavelength range 0.9-2.4 μm. FRIDA is a collaborative project between the main GTC partners

We study photometric variable stars in two open clusters of very different age: σ Orionis (τ ˜ 3 Ma, d ˜ 385 pc) and NGC 6811 (τ ˜ 600 Ma, d ˜ 1000 pc). In NGC 6811 we expected to detect pulsations in known δ Scuti stars that are also observed in the Kepler field, from which we calculate the frequency spectra, and derive information about the

Recent observations show that inner disks and rings (IDs and IRs) are not preferentially found in barred galaxies, pointing to the relevance of formation mechanisms different to the traditional bar-origin scenario. Nevertheless, the role of minor mergers in the formation of these inner components (ICs), while often invoked, is still poorly

These tables contain all the parameters that have been computed, based on the LR8 spectra of targets selected as being foreground Galactic members. The atmospheric parameters were computed using the pipeline presented in Kordopatis et al. (2011A&A...535A.106K). The line-of-sight distances and the projected atmospheric parameters were computed by
