Title: New Simulations and Observations of Highly-complex Molecules in Star-forming Regions

Abstract: Interstellar space is replete with molecules; however, certain high-mass star-forming cores (i.e. "hot cores") in particular demonstrate some of the richest chemistry observed outside the solar system. Our recent 3-mm ALMA line survey (EMoCA) of the chemically-rich Galactic Center high-mass star-forming source Sagittarius B2(N) has identified a selection of new complex organic molecules, whose formation mechanisms are just beginning to be fully explored. These include a new class of molecule for interstellar chemistry: branched aliphatic species, here represented by iso-propyl cyanide (i-C3H7CN), whose straight-chain form (n-C3H7CN) was also detected. The production of many such molecules seems to be strongly dependent on diffusive chemistry on cold dust-grain surfaces, followed by the energetic processing and heating of the resultant ice mantles. Here, I will outline the chemical and physical processes that take place in interstellar/star-forming cores, and will discuss new astronomical detections of organic molecules. I will show how new gas- and solid-phase chemical kinetics simulations, combined with astrophysical spectral-emission models, can help us understand both the chemistry of star formation, and laboratory ice experiments that aim to reproduce that chemistry. I will also discuss prospects for the identification of as-yet undetected complex organic molecules.
