Infrared Spectroscopy and Photochemistry of Aromatic Nitriles in Para-Hydrogen Matrices
Sam McGrath, Vincent J. Esposito, Linshan Zeng +6
Motivated by recent detections of several aromatic nitriles in Taurus Molecular Cloud-1, we report laboratory and theoretical investigations of the vibrational spectroscopy and pho…
Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…
The Computed Microwave Spectrum of the Protonated Fullerene C60H+
Laszlo Nemes, Jos Oomens, Vincent J. Esposito +2
The largest known molecule in space, C60 , has been detected in its neutral and cationic form through its vibrational, UV-driven fluorescence emission spectrum and its electronic a…
PDRs4All: XVIII. The evolution of the PAH ionisation and PAH size distribution across the Orion Bar
Alexandros Maragkoudakis, Christiaan Boersma, Els Peeters +25
We investigate the evolution of the PAH population's charge state and size across key physical zones in the Orion Bar, which include the HII region, the atomic PDR (APDR), and thre…
SPHEREx: Aromatics, Aliphatics and PAH Size across the Iris Nebula
Christiaan Boersma, Alexandros Maragkoudakis, Louis J. Allamandola +4
Observations by the SpectroPhotometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) are combined with Spitzer spectral map data to study the a…
A sensitivity analysis of the modeling of Polycyclic Aromatic Hydrocarbon emission in galaxies
Alexandros Maragkoudakis, Christiaan Boersma, Pasquale Temi +5
We have conducted a sensitivity analysis on the mid-infrared spectral decomposition of galaxies and the modeling of the PAH emission spectrum with the NASA Ames PAH Infrared Spectr…
