Subarcsecond Imaging of the Complex Organic Chemistry in Massive Star-forming Region G10.6-0.4

Massive star-forming regions exhibit an extremely rich and diverse chemistry, which in principle provides a wealth of molecular probes, as well laboratories for interstellar prebiotic chemistry. Since the chemical structure these sources displays substantial spatial variation among species on small scales (${\lesssim}10^4$ au), high angular resolution observations are needed to connect structures local environments inform astrochemical models massive star formation. To address this, we present ALMA 1.3 mm toward OB cluster-forming region G10.6-0.4 (hereafter "G10.6") at 0.14$^{\prime\prime}$ (700 au). We find highly-structured emission from complex organic molecules (COMs) throughout central 20,000 au, including two hot cores several shells or filaments. spatially-resolved rotational temperature column density maps large sample COMs warm gas tracers. These reveal range substructure both O- N-bearing species. identify correlations that can be explained by existing COM formation, NH$_2$CHO/HNCO CH$_3$OCHO/CH$_3$OCH$_3$, but also observe unexpected distributions suggest our current understanding formation is far complete. Importantly, chemistry observed G10.6, rather than being confined cores. The composition appears different compared more extended structures, illustrates importance elucidating physical processes associated with
