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

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

With a mass, radius, and mean density similar to Earth's, the rocky planet GJ 1132 b is the first truly small planet for which an atmosphere detection was proposed. If confirmed, ultra-reduced magma outgassing is the only mechanism capable of producing HCN and H 2O in large enough quantities to match the Hubble Space Telescope observations. The

Cosmological hydrodynamical simulations provide valuable insights on galaxy evolution when coupled with observational data. Comparisons with real galaxies are typically performed via scaling relations of the observables. Here, we follow an alternative approach based on the spectral covariance in a model-independent way. We build upon previous work
