Components of star formation in NGC 253 : Non-negative Matrix Factorization Analysis with the ALCHEMI integrated intensity images
Ryo Kishikawa, Nanase Harada, Toshiki Saito +12
It is essential to examine the physical or chemical properties of molecular gas in starburst galaxies to reveal the underlying mechanisms characterizing starbursts. We used non-neg…
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…
First detection of the 1) methanol maser transitions at and
Pedro K. Humire, Gisela N. Ortiz-León, Antonio Hernández-Gómez +3
Class\,I methanol masers provide sensitive information about the shocked environment around star-forming regions. Among the brightest Class~I methanol masers, we have those in the…
The fountain of the luminous infrared galaxy Zw049.057 as traced by its OH megamaser
Boy Lankhaar, Susanne Aalto, Clare Wethers +15
High resolution (0."037-0."13 [10-35 pc]) e-MERLIN ( cm) and (0."024 [6.5 pc]) ALMA ( mm) observations have been used to image OH (hydroxyl) and HCO (formald…
Physical Properties of the Southwest Outflow Streamer in the Starburst Galaxy NGC 253 with ALCHEMI
Min Bao, Nanase Harada, Kotaro Kohno +19
The physical properties of galactic molecular outflows are important as they could constrain outflow formation mechanisms. We study the properties of the southwest (SW) outflow str…
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…
The ALCHEMI atlas: principal component analysis reveals starburst evolution in NGC 253
Nanase Harada, David S. Meier, Sergio Martín +24
Molecular lines are powerful diagnostics of the physical and chemical properties of the interstellar medium (ISM). These ISM properties, which affect future star formation, are exp…
