Star Formation in Galaxies


Neural Network Constraints of the Physical Parameters of the Central Molecular Zone of NGC253

Behrens et al. 2024


Using a neural network-based physical and chemical model of the NGC253 central molecular zone (CMZ), Behrens etal (2024) derived the physical conditions on 50pc scales.

Complex Organic Molecules Towards the Central Molecular Zone of NGC253

Bouvier et al. 2025


In Galactic star-forming (SF) regions, spatial variations of interstellar complex organic molecules (iCOMs) emission could reflect the source physical structure or different chemical formation pathways. Investigating iCOMs in extragalactic star formation regions may thus provide crucial information about these regions. As an active extragalactic star formation region, the central molecular zone (CMZ) of the nearby galaxy NGC 253 provides an ideal template for studying iCOMs under more extreme conditions. This study investigates the emission of a few selected iCOMs to characterize how the differences between iCOMs are influenced by the chemical and physical structure of the NGC253 CMZ.

Schematic (not to scale) summarising the possible formation pathways and chemical links between iCOMs and their emission origins within a GMC.
