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…
The Critical 9365 Å Diffuse Interstellar Band and C Association
Daniel Majaess, Tina A. Harriott, Halis Seuret +3
The detection of interstellar C has been debated for 30 years. The contested attribution of a weaker DIB at 9365 Å was re-evaluated here on the basis of a Pearson correl…
Potential Vibrational Modes Tied to Diffuse Interstellar Bands
Daniel Majaess, Halis Seuret, Tina A. Harriott +4
Potential vibrational modes associated with diffuse interstellar bands (DIBs) could be discerned by examining energy differences between correlated DIBs. Consequently, $\approx 10^…
Strengthening the Link Between Fullerenes and a Subset of Diffuse Interstellar Bands
Daniel Majaess, Tina A. Harriott, Halis Seuret +3
A debate persists regarding the correlation between the DIBs 9577 and 9632 Å, and whether they share a common molecular carrier (i.e., C). A robust high correlation dete…
Anionic hydrogen clusters as a source of diffuse interstellar bands (DIBs)
Lulu Huang, Cherif F. Matta, Daniel Majaess +3
The sources behind numerous key diffuse interstellar bands (DIBs) remain elusive, and thus evidence is presented here that a family of seven anionic hydrogen atomic clusters (H(-)2…
