Spectroscopy enables key physical insight in the study of exoplanets, stars, galaxies, and the interstellar and intergalactic media. Detailed spectroscopic studies of both bright and faint objects call for high dispersion at large telescopes to increase the photon-collecting area. High-resolution, high-stability spectroscopy is key for the precise

X-ray binaries (XRBs) are arguably the best sources for studying accretion and jets, because they traverse various accretion states with greatly differing jet strength, over timescales of the order of months, easily amenable to observation. Multi-wavelength variability data, combined with timing analysis techniques, provides information about the

The purpose of these fellowship is to promote the incorporation of research staff, Spanish or foreigner, with an outstanding track record, in Spanish R&D centers, in order for them to acquire the skills and abilities that allow them to obtain a stable position in a research body of the Spanish System of Science, Technology and Innovation. The

The purpose of the aid is to train doctors through the financing of employment contracts, under the form of a predoctoral contract, so that the predoctoral research staff in training can carry out a doctoral thesis associated with a research project financed by the aid for R&D projects of the State Subprogram for Knowledge Generation within the

WEAVE-ECOS is an unoriented research project that integrates two senior researchers and their team in order to efficiently exploit the first science data from the new WEAVE spectrograph, which is in the commissioning phase at the William Herschel telescope (WHT), in La Palma (Canary Islands). This multidisciplinary project has been designed to

The project focuses on the study of the effect of the internal structure of temperature and density in ionized nebulae on the determination of their chemical composition. The main objective is to carry out different independent verifications and analyze in depth the repercussions of our recent work published in Nature (Méndez-Delgado et al. 2023)
