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

In the pursuit of promoting diversity, equity, and inclusion (DEI) in the field of Astrophysics and High Energy Physics, a group of young researchers at the Universitat de Barcelona (UB) and the Institute of Cosmos Science (ICCUB), under the scope of the DEI-ICCUB commission, has built a mentoring program for students in the Master of Astrophysics

We have employed a novel way to measure the distance to NGC1052-DF2, using the internal stellar velocity dispersions (σ) of its globular clusters (GCs). We obtained deep (15.1 h), R = 18 200, calcium triplet integrated-light spectra for 10 GCs in NGC1052-DF2 using FLAMES GIRAFFE on VLT. For five GCs, we measured the σ values, along with precision

We report the discovery of BD+05 4868 Ab, a transiting exoplanet orbiting a bright (V = 10.16) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA's Transiting Exoplanet Survey Satellite reveal variable transit depths and asymmetric transit profiles that are characteristic of comet-like tails formed by dusty effluents
