First on-sky tests of LQG control for a 10m-class telescope: prelude on the Gran Telescopio Canarias adaptive optics system
The Gran Telescopio Canarias (GTC) is being equipped with an Adaptive Optics (AO) system, developed by the Instituto de Astrofísica de Canarias (IAC). The...
First Performance of the GOLF-NG Instrumental Prototype Observing the Sun in Tenerife
The primary challenge of Global Oscillations at Low Frequency New Generation (GOLF-NG) is the detection of the low-frequency solar gravity and acoustic modes...
First Release of PLATO Consortium Stellar Limb-darkening Coefficients
We release the first grid of stellar limb-darkening coefficients (LDCs) and intensity profiles (IPs) computed by the consortium of the PLAnetary Transits and...
First Release of the IPHAS Catalogue of Extended Planetary Nebulae
Following a vast search for extended Planetary Nebulae (PNe) in the Galactic Plane using IPHAS, we present the first release of the "IPHAS Catalogue of Extended...
First results and future plans for the Canarias Infrared Camera Experiment (CIRCE) for the Gran Telescopio Canarias
CIRCE is a near-infrared (1-2.5 micron) imager (including low-resolution spectroscopy and polarimetery) in operation as a visitor instrument on the Gran...
First Results from a Study of DIBs with Thousands of High-Quality Massive-Star Spectra
We are using five different surveys to compile the largest sample of diffuse interstellar band (DIB) measurements ever collected. GOSSS is obtaining...
First Results from HST19 GO12600: CNO Abundances in Seven Milky Way Planetary Nebulae
In HST Cycle 19 we observed 10 Milky Way planetary nebulae (PNe) from 1150-10270Å with STIS to obtain accurate abundances of carbon, nitrogen and oxygen. The...
As the epoch of spheroid formation in massive galaxies is believed to correspond to the growth of active nuclei, probing the population of obscured AGN at high...
