Detections of interstellar 2-cyanopyrene and 4-cyanopyrene in TMC-1

Gabi Wenzel, Thomas H. Speak, P. Bryan Changala +19

Polycyclic aromatic hydrocarbons (PAHs) are among the most ubiquitous compounds in the universe, accounting for up to ~25% of all interstellar carbon. Since most unsubstituted PAHs…

Discovery of interstellar 1-cyanopyrene: a four-ring polycyclic aromatic hydrocarbon in TMC-1

Gabi Wenzel, Ilsa R. Cooke, P. Bryan Changala +22

Polycyclic aromatic hydrocarbons (PAHs) are expected to be the most abundant class of organic molecules in space. Their interstellar lifecycle is not well understood, and progress…

High Spectral Resolution Observations of Propynal (HCCCHO) towards TMC-1 from the GOTHAM Large Program on the Green Bank Telescope

Anthony J. Remijan, Zachary T. P. Fried, Ilsa R. Cooke +7

We used new high spectral resolution observations of propynal (HCCCHO) towards TMC-1 and in the laboratory to update the spectral line catalog available for transitions of HCCCHO -…

On the origin of infrared bands attributed to tryptophan in Spitzer observations of IC 348

Aditya Dhariwal, Thomas H. Speak, Linshan Zeng +12

Infrared emission features toward interstellar gas of the IC 348 star cluster in Perseus have been recently proposed to originate from the amino acid tryptophan. The assignment was…

A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk

Olivier Berné, Emilie Habart, Els Peeters +143

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
