Distributions of the Density and Kinetic Temperature of the Molecular Gas in the Central Region of NGC 613 using Hierarchical Bayesian Inference
Hiroyuki Kaneko, Tomoka Tosaki, Kunihiko Tanaka +1
We present position-position-velocity (PPV) cubes of the physical and chemical properties of the molecular medium in the central 1.2 kpc region of the active galaxy NGC 613 at a PP…
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…
ALCHEMI finds a "shocking" carbon footprint in the starburst galaxy NGC~253
Nanase Harada, Sergio Martin, Jeff Mangum +15
Centers of starburst galaxies may be characterized by a specific gas and ice chemistry due to their gas dynamics and the presence of various ice desorption mechanisms. This may res…
Energizing Star Formation: The Cosmic Ray Ionization Rate in NGC 253 Derived From ALCHEMI Measurements of HO and SO
Jonathan Holdship, Jeffrey G. Mangum, Serena Viti +16
The cosmic ray ionization rate (CRIR) is a key parameter in understanding the physical and chemical processes in the interstellar medium. Cosmic rays are a significant source of en…
Starburst Energy Feedback Seen Through HCO/HOC Emission in NGC 253 from ALCHEMI
Nanase Harada, Sergio Martín, Jeffrey G. Mangum +19
Molecular abundances are sensitive to UV-photon flux and cosmic-ray ionization rate. In starburst environments, the effects of high-energy photons and particles are expected to be…
Atomic Carbon in the Central Molecular Zone of the Milky Way : Possible Cosmic-ray Induced Chemistry or Time-Dependent Chemistry Associated with SNR Sagittarius A East
Kunihiko Tanaka, Makoto Nagai, Kazuhisa Kamegai
Being one of the most abundant atomic/molecular species observed in dense molecular gas, atomic carbon () is a potential good tracer of molecular gas mass in many che…
