Detection of two interstellar polycyclic aromatic hydrocarbons via spectral matched filtering
Unidentified infrared emission bands are ubiquitous in many astronomical sources. These
bands are widely, if not unanimously, attributed to collective emissions from polycyclic …

Discovery of two isomers of ethynyl cyclopentadiene in TMC-1: Abundances of CCH and CN derivatives of hydrocarbon cycles
We report the detection of two isomers of ethynyl cyclopentadiene (cC 5 H 5 CCH), namely 1-
and 2-ethynyl-1, 3-cyclopentadiene, in the direction of TMC-1. We derive column densities of …
