Chemistry here and there: Comparison between the CMZ of the Milky Way and NGC 253
Sergio Martín, Álvaro López-Gallifa, David San Andrés +2
For decades, chemical studies in external galaxies have been limited by sensitivity, resolution, bandwidth or a combination of them. A decade of ALMA operations, made the detailed…
Neural Network Constraints on the Cosmic-Ray Ionization Rate and Other Physical Conditions in NGC 253 with ALCHEMI Measurements of HCN and HNC
Erica Behrens, Jeffrey G. Mangum, Serena Viti +15
We use a neural network model and ALMA observations of HCN and HNC to constrain the physical conditions, most notably the cosmic-ray ionization rate (CRIR, zeta), in the Central Mo…
Discovery of MgS and NaS in the Interstellar Medium and tentative detection of CaO
M. Rey-Montejo, I. Jimenez-Serra, J. Martin-Pintado +12
We report the first detection of the metal-bearing molecules sodium sulfide (NaS) and magnesium sulfide (MgS) and the tentative detection of calcium monoxide (CaO) in the interstel…
MagMar III -- Resisting the Pressure, Is the Magnetic Field Overwhelmed in NGC6334I?
Paulo C. Cortes, Josep M. Girart, Patricio Sanhueza +23
We report on ALMA observations of polarized dust emission at 1.2 mm from NGC6334I, a source known for its significant flux outbursts. Between five months, our data show no substant…
