The 1.5-meter GREGOR solar telescope is a new facility for high-resolution observations of the Sun. The telescope is located at the Spanish Observatorio del...
Data for five continuous years (1984 to 1989) at the Teide Observatory (Izaña, Tenerife), obtained with a full-disc solar multi-channel photometer devoted to...
The Ground-Based Observations in Preparation and Support of the Seismology Programme
A vast ground-based observational effort was launched several years ago in order to prepare the optimal selection of targets for the COROT seismology programme...
The growth of massive galaxies due to merging since z˜1 is size independent
Using a large compilation of massive (stellar mass M≥10^{11} M_&sun;) earlytype galaxies (ETGs), we have probed, up to z˜1, whether the presence of satellites...
The growth of the outflows from evolved stars: A live poster
We present our long-term monitoring, using both ground-based telescopes and the HST, of the expansion in the plane of the sky of the outflows from evolved stars...
The growth of the stellar seeds of supermassive black holes
One of the most promising explanations for the origin of the billion solar mass black holes (BHs) inferred to power quasars at redshifts z >= 6 is that...
The GTC Adaptive Optics and Laser Guide Star system (GTCAO-LGS)
The GTC Adaptive Optics (GTCAO) system will provide diffraction-limited capabilities in the near infrared to the GTC telescope. At first, it will use a Natural...
The GTC Adaptive Optics system: the high spatial resolution Adaptive Optics facility at GTC
The GTC Adaptive Optics (GTCAO) system is the general Adaptive Optics facility that will provide diffraction limited images in the near-infrared to the GTC...
