The star-formation main sequence (SFMS) and the mass-metallicity relation (MZR) are two tight, fundamental relations that govern galaxy evolution. Their intrinsic scatter originates from some galaxies having above- or below-average SFR and metallicity, which leads to the question of whether galaxies which are offset from the relations stay there

Ultra-deep optical imaging surveys have reached unprecedented depths (≳30 mag arcsec ‑2; 3σ, 10″ × 10″), thus facilitating the study of very faint galactic structures. However, the ultraviolet bands, which are key to the study of stellar populations, remain essentially unexplored at these depths. In this paper, we present a detailed surface

We present an innovative deblending method that uses the variation of seeing with wavelength to isolate AGN and host galaxy spectra in IFS data. We demonstrate its efficacy through application to MUSE observations of the type I AGN MRK 926.

The Cygnus OB2 association forms the core of the Cygnus-X complex, the closest region to Earth with significant massive star formation. Situated less than 2 kpc away, Cygnus OB2 hosts a young population of OB stars (aged between 1.5 and 6 Myr), making it an ideal laboratory for testing evolutionary channels of massive stars. The newly commissioned

The past decade represented the kick-off and settlement of multi-messenger and time-domain astronomy, coincident with the blooming of transient TeV astronomy. Over the past decade, new sources of very-high-energy (VHE) gamma rays have been discovered, opening new physics in this energy regime: the discovery of a TeV counterpart of long gamma-ray

The Carina Nebula is one of the major and more massive regions of our Galaxy that contains a large number of massive O-type stars that can be analyzed. Benefiting from astrometry by Gaia DR3 and high-quality spectra from different surveys and stellar libraries, a detailed spectroscopic characterization of its O-type stellar content can be performed
