In this work we present merger fractions from galaxy samples selected by either Ks-luminosity, or B-band luminosity, from the GOYA photometric survey of the Groth strip using asymmetry indices to identify merging galaxies. The merger fraction in B-band can be approximated by the function F_{mg}(z) = 0.006(1 + z)^{3.2}. The merger fraction in Ks

Using the UBVIJK photometry from the GOYA Survey of the Groth strip, we have built a catalog with photometric redshifts for 2000 sources (0 z 5). For z 1.5, excellent agreement is found with spectroscopic redshifts ( dz/(1+z) >= 0.07). Such catalog will provide a robust determination of the evolution of the K-band luminosity function, as well as

We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z ˜ 6-11. Lensing magnification improves the search efficiency and subsequent spectroscopic studies with the new generation of NIR multi-object spectrographs (e.g. EMIR/GTC). The UV Luminosity Function derived

The photoabsorption spectra of single-shell icosahedral fullerenes are investigated in the region of the strongest diffuse interstellar band at 4430 Å. According to Hückel and Pariser-Parr-Pople models, several fullerenes (C80, C240, C320, and C540) present transitions in the vicinity of this band. The same semiempirical models also predict a high

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 - 2.5 μm. FRIDA is a collaborative project between the main GTC partners
