The observation and interpretation of the universe in general have played a major role in cultures from different times and epochs. Studying this role is the main goal of a discipline called "cultural astronomy" or "astronomy in culture". With a tradition of more than three decades, it is an interdiscipline halfway between astronomy and social

Planetary nebulAE(PNe) arising from common envelope (CE) interaction represent a kind of embarrassing binary. Asymptotic Giant Branch (AGB) stars in close-binary systems undergoing CE are believed to abruptly eject their remaining envelope, giving rise to the PNe we observe around some of them. Whereas we are confident that angular momentum

We analysed the evolution of the spatial distribution and stratification of the physical parameters of the atmosphere of an X-class flare in the photosphere and chromosphere. We analysed the full Stokes vector of the Fe I 617.3 nm and Ca II 854.2 nm transitions recorded by the Interferometric Bidimensional Spectropolarimeter instrument on the 22

With the evolution of very high-energy (VHE) gamma-ray astronomy, new tools for data analysis are being developed. One of these new tools is Gammapy, a python-package for gamma-ray analysis. In this contribution we will present the preliminary status of an automatic Gammapy-based pipeline able to handle complex regions including multiple point-like

Aims. We have undertaken a reassessment of the distribution of the alpha-element abundance ratios Ne/O, S/O, and Ar/O with respect to metallicity in a sample of about 1000 spectra of Galactic and extragalactic H II regions and star-forming galaxies (SFGs) of the Local Universe. We also analyse and compare different ionisation correction factor (ICF

Giant (>100 kpc) nebulae associated with active galaxies provide rich information about the circumgalactic medium (CGM) around galaxies, its link with the interstellar medium (ISM) of the hosts and the mechanisms involved in their evolution. We have studied the giant nebula associated with the Teacup (z=0.085) obscured quasar based on VLT MUSE
