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…
A temperature or FUV tracer? The HNC/HCN ratio in M83 on the GMC scale
Nanase Harada, Toshiki Saito, Yuri Nishimura +2
The HNC/HCN ratio is observationally known as a thermometer in Galactic interstellar molecular clouds. A recent study has alternatively suggested that the HNC/HCN ratio is affected…
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…
Volume density structure of the NGC253 CMZ through ALCHEMI excitation analysis
Kunihiko Tanaka, Jeffrey G. Mangum, Serena Viti +21
We present a spatially-resolved excitation analysis for the central molecular zone (CMZ) of the starburst galaxy NGC 253 using the data from the ALMA Large program ALCHEMI, whereby…
Molecular Abundance of the Circumnuclear Region Surrounding an Active Galactic Nucleus in NGC 1068 based on Imaging Line Survey in the 3-mm Band with ALMA
Taku Nakajima, Shuro Takano, Tomoka Tosaki +9
We present an imaging molecular line survey in the 3-mm band (85-114 GHz) focused on one of the nearest galaxies with an active galactic nucleus (AGN), NGC 1068, based on observati…
