Characterizing Spatial Variations of PAH Emission in the Reflection Nebula NGC 1333
C. Knight, E. Peeters, M. Wolfire +1
Infrared emission features at 3.3, 6.2, 7.7, 8.6, and 11.2 m, attributed to polycyclic aromatic hydrocarbons, show variations in relative intensity, shape, and peak position. Th…
Tracing PAH Size in Prominent Nearby Mid-Infrared Environments
C. Knight, E. Peeters, D. J. Stock +2
We present observations from the First Light Infrared TEst CAMera (FLITECAM) on board the Stratospheric Observatory for Infrared Astronomy (SOFIA), the Spitzer Infrared Array Camer…
Characterisation of the Planetary Nebula Tc 1 Based on VLT X-Shooter Observations
Isabel Aleman, Marcelo L. Leal-Ferreira, Jan Cami +11
We present a detailed analysis of deep VLT/X-Shooter observations of the planetary nebula Tc 1. We calculate gas temperature, density, extinction, and abundances for several specie…
PAHs and star formation in the HII regions of nearby galaxies M83 and M33
A. Maragkoudakis, N. Ivkovich, E. Peeters +3
We present mid-infrared (MIR) spectra of HII regions within star-forming galaxies M83 and M33. Their emission features are compared with Galactic and extragalactic HII regions, HII…
Polycyclic Aromatic Hydrocarbon emission in Spitzer/IRS maps II: A direct link between band profiles and the radiation field strength
D. J. Stock, E. Peeters
We decompose the observed 7.7 m polycyclic aromatic hydrocarbon (PAH) emission complexes in a large sample of over 7000 mid-infrared spectra of the interstellar medium (ISM) usi…
Interpreting the subtle spectral variations of the 11.2 and 12.7 μm polycyclic aromatic hydrocarbon bands
M. J. Shannon, D. J. Stock, E. Peeters
We report new properties of the 11 and 12.7 μm emission complexes of polycyclic aromatic hydrocarbons (PAHs) by applying a Gaussian-based decomposition technique. Using high-resolu…
