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…
SPHEREx: Aromatics, Aliphatics and PAH Size across the Iris Nebula
Christiaan Boersma, Alexandros Maragkoudakis, Louis J. Allamandola +4
Observations by the SpectroPhotometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) are combined with Spitzer spectral map data to study the a…
A sensitivity analysis of the modeling of Polycyclic Aromatic Hydrocarbon emission in galaxies
Alexandros Maragkoudakis, Christiaan Boersma, Pasquale Temi +5
We have conducted a sensitivity analysis on the mid-infrared spectral decomposition of galaxies and the modeling of the PAH emission spectrum with the NASA Ames PAH Infrared Spectr…
The Background Interstellar Medium as Observed from Off-Order Low-Resolution Spitzer-IRS Spectra
Christiaan Boersma, Jesse D. Bregman, Louis J. Allamandola +2
Spitzer 'hidden' observations of the background are used to construct a catalog of 4,090 spectra and examine the signature of polycyclic aromatic hydrocarbon (PAH) molecules and th…
JWST: Deuterated PAHs, PAH-nitriles, and PAH Overtone and Combination Bands I: Program Description and First Look
C. Boersma, L. J. Allamandola, V. J. Esposito +6
A first look is taken at the NIRSpec 1-5 m observations from JWST program 1591 that targets 7 objects along the low-mass stellar life cycle with PAH emission. Spectra extracted…
