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

Aims. We aim to detect and characterise solar-like oscillations in bright naked-eye (V<6) main-sequence and subgiant stars observed by the Transiting Exoplanet Survey Satellite (TESS). In doing so, we seek to expand the current benchmark sample of oscillators, provide accurate global asteroseismic parameters for these bright targets, and assess

Compact, star-forming galaxies with high star formation rate surface densities (Σ SFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely because intense stellar feedback creates low-density channels that allow photons to escape. Irregular or disturbed morphologies, such as those resulting from mergers, can also facilitate LyC
