Physical and Chemical Conditions of Molecular Gas in NGC 1068: The nuclear feedback in the circumnuclear disk and starburst ring
Bin Jia, Serena Viti, Erica Behrens +1
Molecular gas in galaxies is shaped by both star formation and active galactic nuclei. In NGC 1068, the circumnuclear disk and the starburst ring offer a nearby case to study these…
Testing the Physical Parameter Constraining Power of HCN and HNC with Neural Networks
Erica Behrens, Jeffrey G. Mangum, Mathilde Bouvier +2
We quantify the utility of HCN and HNC to characterize gas conditions in the nearby starburst galaxy NGC 253. We use measurements from the Atacama Large Millimeter/Submillimeter Ar…
Probing the Kinematics of Multiple- and Single-Protostar Systems in Perseus with N2H+
Erica Behrens, Adele Plunkett, Zhi-Yun Li
We analyze the dense gas kinematics in two Class 0/I protostellar cores, Per 30 and NGC 1333 IRAS 7, in the Perseus molecular cloud to determine whether their velocity structures a…
Shock-induced HCNH+ abundance enhancement in the heart of the starburst galaxy NGC 253 unveiled by ALCHEMI
Y. Gong, C. Henkel, C. T. Bop +15
Understanding the chemistry of molecular clouds is pivotal to elucidate star formation and galaxy evolution. As one of the important molecular ions, HCNH+ plays an important role i…
