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

Context. Plages are small concentrations of strong, nearly vertical magnetic fields in the solar photosphere that expand with height. A high spatial and spectral resolution that can resolve their fine structure is required to characterize them, and spectropolarimetric capabilities are needed to infer their magnetic fields. Aims. We constrain the 3D

Microwave and radio observations exhibit some interesting features in the Galactic plane. One of those is the Fan region which is an extended region located in the Perseus arm at a distance of 500 pc. Fan region has highly polarized emission from several MHz up to 353 GHz, which is ascribed to synchrotron but nowadays is largely unexplained. Here
