Emission line galaxies are the most easily detected and studied objects in the high redshift Universe. They are being used to trace the evolution of the critical observables of the Universe such as star formation rate densities, starburst properties, and abundances. The GTC will be a very powerful tool for studying the evolution of emission line

OTELO (OSIRIS Tunable Emission Line Object survey) is a project aimed at studying the low end luminosity function of emission line galaxies. A broad band survey at B ≈ 24 magnitudes detection level will also be performed for a field of view of about 14 square degrees corresponding to the lowest selected redshift (z = 0.08). This huge amount of data

The most prominent feature in the interestellar medium extinction curve is the UV bump at 217.5 nm. The carrier of this band has been frequently associated to some form of carbonaceus material but there is no definitive conclusion on the ultimate responsible of the band. The increase in the extinction at higher energies and the existence of many

We present observations of the 2002 Leonid meteor shower taken with four intensified video cameras from Teide Observatory (Tenerife Spain) on November 19 2002. The cameras fitted with f/1.4 85 mm objectives were aimed at 6 deg above the horizon in order to monitor the largest atmospheric volume possible. The most sensitive camera detected 1300

We measured the bar pattern speed of a sample of 6 SB0 galaxies using the Tremaine-Weinberg method. We derived the ratio, {cal R}, of the corotation radius to the length of the bar semi-major axis. For all the galaxies, {cal R} is consistent with being in the range from 1.0 and 1.4, i.e. that they host fast bars. This represents the largest sample
