CARMENES is an instrument designed to search for extrasolar planets around M dwarfs with the radial-velocity technique. It consists of two independent high...

Using the UBVIJK photometry from the GOYA Survey of the Groth strip, we have built a catalog with photometric redshifts for 2000 sources (0 z 5). For z 1.5...

In this work we present merger fractions from galaxy samples selected by either Ks-luminosity, or B-band luminosity, from the GOYA photometric survey of the...

We present U and B galaxy number counts from a field that comprises a 0.29 square degrees area of sky, and which covers the Groth-Westphal Strip (Groth et al...

Greenhouse gas emissions in Spain in 2008-2009 were 34.3 % higher than the base-year level, significantly above the burden-sharing target of 15 % for the period...

New bidimensional spectroscopic observations of A78 allow the authors to determine the He, O, Ne, and N abundances and their variations along the nebula. A...

The use of long-slit spectroscopy at high spectral and spatial resolution has made it possible to measure gradients of gaseous excitation and also velocity...

Images of the coma through continuum filters during EPOXI fly-by show that the comet's periodic activity is dominated by two active regions. They produce dust...

During the mid 1990s, extensive archaeoastronomical fieldwork was performed in the island of Gran Canaria, which is the richest of the Canaries from the...
