An ALCHEMI inspection of sulphur-bearing species towards the central molecular zone of NGC 253
M. Bouvier, S. Viti, E. Behrens +19
Sulphur-bearing species are detected in various environments within Galactic star-forming regions and are particularly abundant in the gas phase of outflows and shocks, and photo-d…

Molecular isotopologue measurements toward super star clusters and the relation to their ages in NGC253 with ALCHEMI
J. Butterworth, S. Viti, P. P. Van der Werf +18
Determining the evolution of the CNO isotopes in the interstellar medium (ISM) of starburst galaxies can yield important constraints on the ages of superstar clusters (SSCs), or on…

Reconstructing the shock history in the CMZ of NGC 253 with ALCHEMI
K. -Y. Huang, S. Viti, J. Holdship +19
HNCO and SiO are well known shock tracers and have been observed in nearby galaxies, including the nearby (D=3.5 Mpc) starburst galaxy NGC 253. The simultaneous detection of these…
