Multiwavelength Study of Photodissociation Regions and a Near -Infrared Imager
… maps of the high-density PDR in the Orion Bar were used to evaluate the PDR nitrogen chemistry model calculated by Tielens & Wolfire. The morphology of the molecular gas is demonstrated. We also found that the production of HCN and HCO+ occurs mainly in dense clumps near the PDR …

Revisiting polycyclic aromatic hydrocarbon emission in Photodissociation regions
… emission features predicted by our model in the Orion Bar, NGC 2023, NGC 7023, the Horsehead nebula, and the diffuse ISM compare well to those obtained from observations. Furthermore, the results of our model highlight the necessity of experimentally determined electron-recombination rates of …
