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…

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…

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…

Tracing the chemical footprint of shocks in AGN-host and starburst galaxies with ALMA multi-line molecular studies

Ko-Yun Huang, Serena Viti

Multi-line molecular observations are an ideal tool for a systematic study of the physico-chemical processes in the Interstellar Medium (ISM), given the wide range of critical dens…

Hydrodynamic simulations of the Disk of Gas Around Supermassive black holes (HDGAS) -I; Molecular Gas Dynamics

Mojtaba Raouf, Serena Viti, S. García-Burillo +9

We present hydrodynamic simulations of the interstellar medium (ISM) within the circumnuclear disk (CND) of a typical AGN-dominated galaxy influenced by mechanical feedback from an…

Tracing Interstellar Heating: An ALCHEMI Measurement of the HCN Isomers in NGC 253

Erica Behrens, Jeffrey G. Mangum, Jonathan Holdship +17

We analyze HCN and HNC emission in the nearby starburst galaxy NGC 253 to investigate its effectiveness in tracing heating processes associated with star formation. This study uses…
