NASIM: Revealing the Low Surface Brightness Universe from Legacy VISTA Data

Automatic reproducible paper pipeline for the paper titled "NASIM: Revealing the Low Surface Brightness Universe from Legacy VISTA Data" accepted for publication in the A&A Journal. In this paper, we present NASIM (Near-infrared Automated low Surface brightness reduction In Maneage), a fully automated and reproducible data reduction pipeline optimised for VISTA/VIRCAM observations. NASIM builds on advanced techniques from the GNU Astronomy Utilities (Gnuastro) to effectively remove large-scale instrumental artefacts and detector patterns while preserving faint, diffuse emission crucial for low surface brightness (LSB) science.
