The COSMOS Survey is currently mapping 0.5 deg2 of sky in optical and near-IR bands to definesamples of compact galaxies at high redshift for spectroscopic studies with the GTC. We present galaxy counts in the Ks filter over an area of 120 arcmin2 in two fields, Coppi and Groth, observed with the INGRID near-infrared camera on the William Herschel

The kinematics of the inner zones of disc galaxies have recently been shown to be much more complicated than previously thou-ght. New instruments and more sensitive detectors have allowed us to obtain spectra of higher S/N ratio and resolution, as well as images, for a more refined study of these inner zones. Decoupled kinematic cores have been

ISOPHOT, the imaging spectro-photo-polarimeter on board ISO, supported performance of aperture and mapping photometry, low-resolution spectroscopy and polarimetry, both in staring and chopped mode. In addition, the 170 μm ISOPHOT Serendipity Survey was performed while slewing from one target to the next. Its calibration had to be connected to the

From the emission line map in Hα over the full face of the spiral galaxy NGC 3359, we analyze the internal velocity structure of the H II region population. The emission line profiles show central peaks, with turbulent velocity widths of

Primitive bodies (comets, Centaurs, trans-Neptunian objects, etc.) are the best-preserved remnants of the Solar Nebula. Their composition and structure harbor clues to the origin of solar and exosolar planets and the evolution of protoplanetary disks. The capabilities of the Gran Telescopio Canarias (GTC) and its instrumentation provide us a unique
