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…

Evaluating Cepheid Metallicity Effect Determinations via IC1613 and Gaia-independent Parallaxes
Daniel Majaess
18 HST parallaxes for Galactic classical Cepheids are unified to establish a Gaia-independent IC1613 distance and evaluate metallicity effect determinations, since the Gaia zeropoi…

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…
