Given the very close proximity of their habitable zones, brown dwarfs (BDs) represent high-value targets in the search for nearby transiting habitable planets that may be suitable for follow-up occultation spectroscopy. In this paper, we develop search strategies to find habitable planets transiting BDs depending on their maximum habitable orbital

Massive stars are fundamental drivers of the Universe because of their injection of energy, momentum, and nuclear-processed material in every stage of their life and death. Their feedback depends on their formation, winds and evolution, and these in turn depend on chemical composition. The GTC-OSIRIS combination is an excellent machine for

Massive galaxies have grown a factor of 4 in size since z=2 to the present. The reasons of this growth remain unclear. Within the possible mechanisms that have been suggested to explain this evolution, the accretion of satellites by the massive galaxies seems to be the most promising one. To understand the details of this growth we have performed a

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
