Broadband Analysis of TMC-1: Composition and Astrochemical Variety Explored

Abstract

The study of interstellar chemistry delves into the very origins of molecules in the universe. The modern methodology of detecting molecules through rotational spectroscopy commenced more than half a century ago, driven by a profound question: How well do we truly comprehend the chemistry unfolding in conditions beyond our planet? The GBT is a world leading facility in the field of astrochemistry and the results of the GOTHAM large program have uncovered a rich molecular inventory toward the cold core TMC-1. These discoveries range from 7-ring polycyclic aromatic hydrocarbons (PAHs) to very long, unsaturated C-chains. Despite all the success, there is still untapped discovery space as our observations are signal-to-noise limited. This study will continue our efforts of GOTHAM with a Broadband Analysis of TMC-1: Composition and Astrochemical Variety Explored (BATCAVE) to accumulate the deepest, spectral line survey of TMC-1 every attempted at X-band with the ultimate goal of continuing to push the boundaries of molecular detection and gain deeper insights into the intriguing molecular complexities contained in TMC-1.
