Last two years the GTC control system has continued its design and prototyping activity. This paper presents the current state of the GTC control system...
Are 16 bits really needed in CCDs and infrared detectors for astronomy?
One of the problems found in the design of the electronics for astronomical instruments is the difficulty to find precise digitizers (16 bits) at high speed. In...
Are active galaxies different at large-scale than their non-active twin galaxies?
In this contribution, we will show our results from a sample of 20 pairs of nearby seemingly isolated twin galaxies differing in nuclear activity. Firstly, we...
We present a comparison of the spin parameter λ R, measured in a region dominated by the galaxy disc, between 20 pairs of nearby (0.005 < z < 0.03) seemingly...
Main Belt Comets (MBCs) are objects of the main belt with observed sporadic cometary-like activity (Hsieh and Jewitt 2006, Science, 312, 561). The study of...

Are dark gaps in barred galaxies a signature of bar corotation?
Stellar bars in galaxies induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of 'dark-gaps'...
