A new hot core in the outer Galaxy: Impact of metallicity on the formation of complex organic molecules
Youxin Wang, Arnaud Belloche, Robin T. Garrod
Many complex organic molecules (COMs) in star-forming regions are believed to form on dust grains. We thus expect both the reduced metallicity and dust-to-gas ratio in the outer Ga…

Reexploring Molecular Complexity with ALMA: Insights into chemical differentiation from the molecular composition of hot cores in Sgr B2(N2)
A. Belloche, R. T. Garrod, H. S. P. Müller +3
We used ALMA to perform a line survey of the high-mass star forming region Sgr B2(N), called ReMoCA. We modeled under the assumption of LTE the spectra obtained toward the sources…

The salty emission of the intermediate-mass AGB star OH 30.1 -0.7
T. Danilovich, A. M. S. Richards, M. Van de Sande +17
We analyse continuum and molecular emission, observed with ALMA, from the dust-enshrouded intermediate-mass AGB star OH 30.1 -0.7. We find a secondary peak in the continuum maps, "…
