O objetivo deste trabalho foi a investigação das propriedades ópticas da amostra LiGaSiO4 contendo Fe3+ como impureza substitucional. Materiais do tipo óxido dopados com metais de transição...
The metallicities of luminous, massive field galaxies at intermediate redshifts (2006)
Mouhcine, M., Bamford, S. P., Aragon-Salamanca, A., Nakamura, O.
We derive oxygen abundances for a sample of 40 luminous (M_{B} < -19), star-forming, mostly disk, field galaxies with redshifts in the range 0.2 < z < 0.8$, with a median of = 0.45. Oxygen...
Mouhcine, M., Bamford, S. P., Aragon-Salamanca, A., Nakamura, O.
We examine the evolutionary status of luminous, star-forming galaxies in intermediate-redshift clusters by considering their star formation rates and the chemical and ionsiation properties of their...

Nakamura, O., Aragon-Salamanca, A., Milvang-Jensen, B., Arimoto, N., Ikuta, C., Bamford, S. P.
We have carried out spectroscopic observations in 4 cluster fields using Subaru's FOCAS multi-slit spectrograph and obtained spectra for 103 bright disk field and cluster galaxies at $0.06 \le z \le...
Evolution of metals and dust in the universe (2005)
Khare, P, Kulkarni, V. P, Lauroesch, L. T, Fall, S. M, York, D. G, Welty, D. E, ...
With the aim of determining the evolution of metals and dust in the universe, we have observed 8 Damped Lyman-alpha Absorbers (DLAs) with the Multiple Mirror Telescope and the Hubble Space Telescope...
The Luminosity and Color Dependence of the Galaxy Correlation Function (2004)
Zehavi, I., Zheng, Z., Weinberg, D. H., Frieman, J. A., Berlind, A. A., Blanton, M. R., ...
We study the luminosity and color dependence of the galaxy 2-point correlation function in the Sloan Digital Sky Survey, starting from a sample of 200,000 galaxies over 2500 deg^2. We concentrate on...
Sloan Digital Sky Survey: Early data release (2002)
Stoughton, C., Lupton, R. H., Bernardi, M., Blanton, M. R., Burles, S., Castander, F. J., ...
The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of 10 6 galaxies, 100,000...

Thermal and optical properties of porous silicon (2001)
Silva,A. Ferreira Da, Silva,T. Souza Da, Nakamura,O., Pepe,I., Roman,L. S., ...
Thermal diffusivity and optical absorption have been investigated for porous silicon, at room temperature, using photoacoustic spectroscopy. The experimental results obtained conform well with the...
