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…
On the effects of UV photons/X-rays on the chemistry of the Sgr B2 cloud
J. Armijos-Abendaño, J. MartÃn-Pintado, E. López +7
The lines of HOC, HCO and CO are considered good tracers of photon-dominated regions (PDRs) and X-ray dominated regions. We study these tracers towards regions of the Sgr B…
Complex Organic Molecules towards the central molecular zone of NGC 253
M. Bouvier, S. Viti, J. G. Mangum +9
Interstellar complex organic molecules (iCOMs) may have a link to prebiotic species, key building blocks for life. In Galactic star-forming (SF) regions, spatial variations of iCOM…
ALCHEMI: an ALMA Comprehensive High-resolution Extragalactic Molecular Inventory. Survey presentation and first results from the ACA array
S. MartÃn, J. G. Mangum, N. Harada +32
We used the Atacama Large Millimeter/submillimeter Array (ALMA), covering a nearly contiguous 289 GHz frequency range between 84.2 and 373.2 GHz, to image the continuum and spectra…
The Distribution and Origin of CH in NGC 253 from ALCHEMI
J. Holdship, S. Viti, S. MartÃn +18
Observations of chemical species can provide an insight into the physical conditions of the emitting gas but it is important to understand how their abundances and excitation vary…
Exploring the molecular chemistry and excitation in obscured luminous infrared galaxies: An ALMA mm-wave spectral scan of NGC 4418
F. Costagliola, K. Sakamoto, S. Muller +7
We obtained an ALMA Cycle 0 spectral scan of the dusty LIRG NGC 4418, spanning a total of 70.7 GHz in bands 3, 6, and 7. We use a combined local thermal equilibrium (LTE) and non-L…
