IntroductionThe C≡N functional group (hereafter CN) can be incorporated into a diverse range of molecular structures, ranging from simpler cyanides like HCN to semi-refractory salts like NH4+OCN- and larger and more complex polymeric refractory material. In astrophysical settings, CN-bearing compounds form and evolve through thermal, photochemical

Massive young clusters with rich populations of high-mass stars are ideal laboratories to explore their evolutionary paths. Despite being the most prominent cluster in the Perseus-arm Cas OB8 association, NGC 663 remains comparatively little studied. We present a comprehensive investigation of its properties, integrating astrometric, photometric

Near-infrared imaging is a powerful technique in observational astronomy, but the bright background – primarily from the Earth's atmosphere – makes the detection of faint features particularly challenging. To recover low surface brightness (LSB) structures in such data, we present NASIM (Near-infrared Automated low Surface brightness reduction In

Context. Understanding massive star multiplicity is essential for constraining formation scenarios, binary evolution, and stellar feedback in galaxies. The MONOS (Multiplicity Of Northern O-type Spectroscopic systems) project aims to characterize O-type spectroscopic binaries in the northern hemisphere (δ > ‑20°), combining high-resolution

We present an analysis of the multi-phase gas properties in the Seyfert II galaxy NGC 424, using spatially resolved spectroscopic data from JWST/MIRI, part of the Mid-InfraRed Activity of Circumnuclear Line Emission (MIRACLE) programme, as well as VLT/MUSE and ALMA. We traced the properties of the multi-phase medium, from cold and warm molecular

Aims. This paper explores and analyses the gas metallicity gradients in a sample of 25 nearby galaxies using new integral field spectroscopy observations from the Metal-THINGS survey, for a total of 102 individual pointings. We derive and analyse the resolved diffuse ionised gas content, Baldwin, Phillips, & Terlevich diagrams, and gas
