Interstellar X-ray Absorption and Scattering
Linli Yan, Aigen Li, Fangjun Lu
Accurate estimates of the absorption of X-rays by interstellar gas and dust are of crucial importance for the analysis and interpretation of almost all astronomical soft X-ray obse…
PDRs4All III: JWST's NIR spectroscopic view of the Orion Bar
Els Peeters, Emilie Habart, Olivier Berne +135
(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
The 2175 Angstrom Interstellar Extinction Bump: Is the Wavelength Variable?
Qian Wang, X. J. Yang, Aigen Li
The most striking characteristics of the mysterious 2175 Angstrom extinction bump, the strongest spectroscopic absorption feature seen on the interstellar extinction curve, are the…
Evidence that Shocks Destroy Small PAH Molecules in Low-luminosity Active Galactic Nuclei
Lulu Zhang, Luis C. Ho, Aigen Li
We combined mapping-mode mid-infrared Spitzer spectra with complementary infrared imaging to perform a spatially resolved study of polycyclic aromatic hydrocarbons (PAHs) emission…
Dust emission at 8-mic and 24-mic as Diagnostics of HII Region Radiative Transfer
M. S. Oey, J. Lopez-Hernandez, J. A. Kellar +10
We use the Spitzer SAGE survey of the Magellanic Clouds to evaluate the relationship between the 8-mic PAH emission, 24-mic hot dust emission, and HII region radiative transfer. We…
