We present initial follow-up results of the ELAIS Deep X-ray Survey which is being undertaken with the Chandra and XMM-Newton Observatories. 235 X-ray sources...

We study the possibility of relaxing the cosmological bound on the Higgs mass coming from the requirement of non-erasure of the baryon asymmetry by sphalerons...

We present the first targeted survey for Extremely Low Mass (ELM) white dwarfs (WDs), helium core WDs with masses

ELMER is a multi-purpose instrument for the GTC designed for both, imaging and spectroscopy in the visible range. The detection subsystem consists of a single...

R stars are carbon stars, less luminous and hotter than the carbon stars evolving along the AGB phase. Thus, their carbon enrichment cannot be a consequence of...

Radio, infrared, and optical observations of the embedded infrared cluster IRAS17136 - 3617 are reviewed. The cluster consists of more than 25 stars with a...

The magnetic activity in the atmosphere of the Sun, possibly of most other magnetically active late-type stars, is a consequence of the emergence of magnetic...

One of the main problems facing development teams working on instrument control systems consists on the need to access mechanisms which are not available until...

EMIR is a near-infrared (NIR) multi-object spectrograph (MOS) proposed for first-generation common user instrument of the Gran Telescopio Canarias GTC. It has...
