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…
Disentangling Multiple Emitting Components in Molecular Observations with Non-negative Matrix Factorization
Damien de Mijolla, Jonathan Holdship, Serena Viti +1
Molecular emission from the galactic and extragalactic interstellar medium (ISM) is often used to determine the physical conditions of the dense gas. However, even from spatially r…
GMC Collisions As Triggers of Star Formation. IX. Chemical Evolution
Chia-Jung Hsu, Jonathan C. Tan, Jonathan Holdship +5
Collisions between giant molecular clouds (GMCs) have been proposed as a mechanism to trigger massive star and star cluster formation. To investigate the astrochemical signatures o…
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…
Reconstructing the shock history in the CMZ of NGC 253 with ALCHEMI
K. -Y. Huang, S. Viti, J. Holdship +19
HNCO and SiO are well known shock tracers and have been observed in nearby galaxies, including the nearby (D=3.5 Mpc) starburst galaxy NGC 253. The simultaneous detection of these…
Investigating the impact of reactions of C and CH with molecular hydrogen on a glycine gas-grain network
Johannes Heyl, Thanja Lamberts, Serena Viti +1
The impact of including the reactions of C and CH with molecular hydrogen in a gas-grain network is assessed via a sensitivity analysis. To this end, we vary 3 parameters, namely,…
