Exploring the Limits of Spectral Line Stacking in Spectral Line Data and Application Toward the Detection of Bulk ${}^{13}$C Enrichment of Aromatics in TMC-1

Miya Duffy, Ryan A. Loomis, Martin S. Holdren +9

The paper evaluates spectral line stacking and matched‑filter techniques to detect faint 13C‑substituted aromatic molecules in the cold cloud TMC‑1, demonstrating the method’s abil…
