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…
On the Anticipation of Lunar Travel in the Early 20th Century: A Pedagogical Exercise
Tina A. Harriott, Cherif F. Matta
This article examines, from historical and pedagogical perspectives, Alphonse Berget's anticipation of Earth-Moon travel in Le Ciel (Larousse, 1923), decades before the beginning o…
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…
