GOTHAM Data
GOTHAM is a broadband spectral line survey of the cold core Taurus Molecular Cloud-1 (TMC-1) Cyanopolyyne Peak with the Green Bank Telescope. Its primary goal is to investigate the chemical conditions of this region, characterized by dark cloud chemistry rich in unsaturated long-carbon-chain and aromatic molecules. Acknowledgement For publications that make use of these data…
