Growth of Massive Bulges by Mergers of Dense Satellites
We present merger models suggesting that bulge growth via accretion of dense satellites generates two of the observed trends of galaxies along the Hubble...
GSC04778-00152 photometry and spectroscopy (Tuvikene+, 2008)
CCD photometry of GSC04778-00152 was carried out on 54 nights during 9 observing runs. In January 2006 the observations were made with the 41-cm Meade telescope...
GT2318+620 - a Galactic Low-Mass X-Ray Binary or a Radio Loud AGN?
GT2318+620 is a variable radio source exhibiting a jet-like feature on both sides of an unresolved core (Taylor et al., Nature 351, 1991), and it is possibly...
The GTC (Gran Telescopio Canarias) employs an Acquisition and Slow Guiding Sensor based on a Marconi CCD47-20. This chip is also the core sensor for the...
GTC adaptive optics first performance tests in laboratory
The GTC AO system designed and developed during the last years is based on a single deformable mirror with 21 x 21 actuators, conjugated to the telescope pupil...
GTC and OSIRIS: expanding the metallicity horizon of massive stars knowledge
Massive stars are fundamental drivers of the Universe because of their injection of energy, momentum, and nuclear-processed material in every stage of their...
The GTC project is in charge of the construction of an optical/IR 10-meter class telescope at the Observatorio del Roque de los Muchachos in Canary Islands. The...
GTC data exploitation in the search for the first galaxies
Detecting the first galaxies of the Universe has always been a goal in extragalactic astronomy because the study of these sources provides important constraints...
