The mid-infrared molecular inventory towards Orion IRc2
Sarah Nickerson, Naseem Rangwala, Sean W. J. Colgan +8
We present the first high spectral resolution mid-infrared survey in the Orion BN/KL region, covering 7.2 to 28.3 micron. With SOFIA/EXES we target the enigmatic source Orion IRc2.…
The First Mid-Infrared Detection of HNC in the Interstellar Medium: Probing the Extreme Environment Towards the Orion Hot Core
Sarah Nickerson, Naseem Rangwala, Sean Colgan +7
We present the first mid-infrared (MIR) detections of HNC and H13CN in the interstellar medium, and numerous, resolved HCN rovibrational transitions. Our observations span 12.8 to…
Fully anharmonic infrared cascade spectra of polycyclic aromatic hydrocarbons
Cameron J. Mackie, Tao Chen, Alessandra Candian +2
The infrared (IR) emission of polycyclic aromatic hydrocarbons (PAHs) permeates our universe; astronomers have detected the IR signatures of PAHs around many interstellar objects.…
High Spectral Resolution SOFIA/EXES Observations of C2H2 towards Orion-IRc2
Naseem Rangwala, Sean W. J. Colgan, Romane Le Gal +8
We present high-spectral resolution observations from 12.96 - 13.33 microns towards Orion IRc2 using the mid-infrared spectrograph, EXES, on SOFIA. These observations probe the phy…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 μm region: Role of periphery
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +5
In this work we report on high-resolution IR absorption studies that provide a detailed view on how the peripheral structure of irregular polycyclic aromatic hydrocarbons (PAHs) af…
High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons: the realm of anharmonicity
Elena Maltseva, Annemieke Petrignani, Alessandra Candian +6
We report on an experimental and theoretical investigation of the importance of anharmonicity in the 3 micron CH stretching region of Polycyclic Aromatic Hydrocarbon (PAH) molecule…
