NEFER (Nuevo Espectrómetro Fabry-Perot de Extrema Resolución) is a high spectral resolution, scanning Fabry-Perot Spectrometer. It will be installed in the OSIRIS instrument at the GTC 10 m telescope. This 3D instrument uses a high order scanning Fabry-Perot to obtain highly accurate kinematical information of extended cosmic sources such as

Aims: The characterisation of the stellar population in young high-mass star-forming regions allows fundamental cluster properties like distance and age to be constrained. These are essential when using high-mass clusters as probes for conducting Galactic studies. Methods: NGC 7538 is a star-forming region with an embedded stellar population

In this paper we present the differences and similarities found between Low Ionization Narrow Emission Regions (LINERs) and Seyfert 2s based on their X-ray and optical emission. We have performed a careful study of the X-ray nuclear properties of a sample of 82 of these LINERs [1, 2, 3]. Around 90% of our sample galaxies show evidences of hosting

Multi-Conjugate Adaptive Optics (MCAO) will play a key role in future astronomy. Every Extremely Large Telescope (ELT) is being designed with its MCAO module, and most of their instruments will rely on that kind of correction for their optimum performance. Many technical challenges have to be solved in order to develop MCAO systems. One of them
