We present an spectroscopic study of a sample of bright gamma-ray blazars. Our dataset includes spectra of a sample of about 10 targets, all of them Flat-Spectrum Radio Quasars (FSRQs). The spectra were obtained nearly periodically during the period from 2008 to 2018. We have used a fitting code (PyQSOFit) specifically developed to model the

Ion fast ignition by laser-driven ion beams is an interesting approach within the inertial confinement fusion scheme to achieve nuclear fusion. In the ion fast ignition, once the precompression of the target is finished, a sphere of fully ionized deuterium-tritium (DT) is obtained. In this work, we have investigated the following stages: heating of

Context. We investigate the physico-chemical properties of the planetary nebula (PN) NGC 3242 in both 1D and 2D, using integral field unit (IFU) data. This PN has a complex morphology with multiple shells and contains a pair of structures with a lower degree of ionization compared to the main nebular components. The origin of these so-called low

We report the discovery of emission lines in the optical spectra of ultracompact massive galaxies (UCMGs) from INSPIRE including relics, which are the oldest galaxies in the Universe. Emission-lines diagnostic diagrams suggest that all these UCMGs, independently of their star formation histories, are 'retired galaxies'. They are inconsistent with

One of the most outstanding astrochemistry problems, since the advent of the IRAS satellite, is the identification of the chemical carriers (structure and composition) of the cosmically widespread unidentified infrared (UIR) emission features. The mid-infrared spectra of a particular group of evolved stars like fullerene-rich planetary nebulAE(PNe)

The Javalambre Physics of the Accelerating Universe Survey (J-PAS) has started observing wide areas of the northern sky with its unique set of 56 filters: 54 narrow band and 2 broader filters that cover the full optical range and effectively deliver a low-resolution spectrum for every object detected. Observations are carried out from the dedicated
