GBT25A-218

A Deep Targeted Line Survey of TMC-1 at X-band - Continuing Our Pilot Study

Abstract

In semester 24A, we were afforded an opportunity to perform a deep study of TMC-1 at X-band to search for some of the most complex molecules every discovered by radio astronomy. The modern methodology of detecting molecules through rotational spectroscopy is 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, and now from the original pilot observations, have uncovered a rich molecular inventory toward TMC-1 and opened up new discovery space that we are using to understand of the chemistry under the most extreme conditions in the interstellar medium. We are asking to continue the study into the lower frequency regime of X-band. Our observing team has used the previous time wisely to refine our data processing pipeline and observing techniques based on the results of the first study. In this study we will continue 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.
