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…
The Nearby Evolved Stars Survey II: Constructing a volume-limited sample and first results from the James Clerk Maxwell Telescope
P. Scicluna, F. Kemper, I. McDonald +89
The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of 850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths, observed in the CO (21) and…
Characterizing the PAH Emission in the Orion Bar
C. Knight, E. Peeters, A. G. G. M. Tielens +1
We present 5--14~m spectra at two different positions across the Orion Bar photodissociation region (PDR) obtained with the Infrared Spectrograph onboard the Spitzer Space Teles…
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…
