Concerns regarding recurrent fluorescence's impact on smaller diffuse ISM aromatics
Daniel Majaess, Cercis Morera-Boado, Tina A. Harriott +1
Recent research implied that recurrent fluorescence (RF) could bolster smaller aromatics against fragmentation in the diffuse ISM, yet that hypothesis is contested by timescales fo…

Benchmarking Astrochemistry Paradigms: Relative Absence of C6H5CN+ in the Diffuse ISM
Daniel Majaess, Cercis Morera-Boado, Tina A. Harriott +4
The detectability of C6H5CN+ (benzonitrile cation) in the diffuse ISM is re-evaluated. A holistic evidentiary framework suggests C6H5CN+ is relatively absent in the diffuse ISM owi…
