PDRs4All XXII. Near-Infrared continuum in the Orion Bar
Takashi Onaka, Emmanuel Dartois, Els Peeters +13
Conspicuous excess emission is present in the near-infrared (NIR) region in various objects, including reflection nebulae, planetary nebulae, and nearby galaxies. However, the spat…

PDRs4All: XVIII. The evolution of the PAH ionisation and PAH size distribution across the Orion Bar
Alexandros Maragkoudakis, Christiaan Boersma, Els Peeters +25
We investigate the evolution of the PAH population's charge state and size across key physical zones in the Orion Bar, which include the HII region, the atomic PDR (APDR), and thre…

PDRs4All XIX. The 6 to 9 m region as a probe of PAH charge and size in the Orion Bar
Baria Khan, Samuel A. Daza Rodriguez, Els Peeters +24
Infrared emission from polycyclic aromatic hydrocarbons (PAHs) play a major role in determining the charge balance of their host environments that include photo-dissociation region…
