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…

High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 micron region: role of hydrogenation and alkylation

E. Maltseva, C. J. Mackie, A. Candian +6

Aims. We aim to elucidate the spectral changes in the 3 micron region that result from chemical changes in the molecular periphery of polycyclic aromatic hydrocarbons (PAHs) with e…

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…
