The forthcoming New Robotic Telescope, a collaboration between the UK and Spain, is poised to become the world's largest and fastest autonomous observatory, located in La Palma. It is tailored to be a premier 4m class follow-up facility for the imminent wave of time-domain and transient astrophysics. It exemplifies innovation with its use of

The European Solar Telescope (EST) is a 4-m class solar telescope that will include a Multiconjugate Adaptive Optics system (MCAO) integrated in the telescope optical path. Its open-dome configuration implies that the complete telescope will be exposed to wind, having an important impact in image stability and quality. The integration of Active

Detached eclipsing binaries (DEBs) and astrometric binaries provide the opportunity for model-independent dynamical mass determination up to very high accuracy. For the stellar modelling and age-dating, freezing the model-independent mass is the most important and critical constraint to limit systematic uncertainties. In addition, stellar radii can

The search for the electromagnetic counterparts to Gravitational Wave (GW) events has been rapidly gathering pace in recent years thanks to the increasing number and capabilities of both gravitational wave detectors and wide field survey telescopes. Difficulties remain, however, in detecting these counterparts due to their inherent scarcity

CARMENES is an instrument designed to search for extrasolar planets around M dwarfs with the radial-velocity technique. It consists of two independent high-resolution echelle spectrographs for the visible and near-infrared wavelength ranges, which are simultaneously fed through fibers from a front end at the Cassegrain focus of the 3.5m telescope

EMIR (Espectrografo Multiobjeto Infra-Rojo) is a wide field, near infrared, multiobject spectrograph, with image capabilities, which is currently located at one of the Nasmyth focus of the 10.4m GTC (Gran Telescopio Canarias). It allows observers to obtain many intermediate resolution spectra simultaneously, in the near IR bands: Z, J, H and K. A
