Investigating the Molecular Inventory of the Extended Green Object: G14.33–0.64

Extended Green Objects are important signposts of the early stages of massive star formation, providing valuable insights into the physical and chemical conditions of embedded protostellar environments. As part of an on going study, we have obtained broadband spectral observations of five EGOs with the Yebes 40m telescope to investigate their molecular inventories. Here, we present an analysis of archival ALMA Band 6 observations of the nearest source in our sample, G14.33–0.64, which serves as a benchmark for interpreting the complementary single-dish data. We perform spectral line identification and present the 1.3mm continuum emission, highlighting the locations of previously reported cm-continuum emission and maser spots. The ALMA spectra reveal a chemically rich environment containing numerous complex organic molecules. A rotational diagram analysis of multiple CH 3 OH and CH 3 CN transitions yields an estimate of the emitting gas’s excitation temperature. These results demonstrate the chemical richness and embedded protostellar activity within G14.33-0.64 and provide the foundation for a comprehensive investigation of its molecular inventory, chemistry, and kinematics. A detailed analysis combining the ALMA and Yebes 40m observations will be presented in [7].
